|This article is about a/an rider in Kamen Rider Build.|
Gentoku Himuro (氷室 幻徳 Himuro Gentoku) was the former head of the Touto Institute of Advanced Matter Physics and briefly took over the role of Prime Minister of Touto from his then-hospitalized father, a position overshadowed by his late-superior, Juzaburo Namba.. Gentoku was also the co-founder and former leader of Faust, and the true identity of Night Rogue, a mysterious masked figure present during Faust's experiments that turn victims into Smash, including the one from Sento Kiryu's memories. . After falling out with Build and being exiled from Touto by his own father, he aligned himself with Seito and underwent grueling training in order to earn the right to be their Rider representative, Kamen Rider Rogue (仮面ライダーローグ Kamen Raidā Rōgu). Shortly after the proxy battle however, he betrayed Namba and formed an alliance with Sento to fight against Evolto until his death.
Gentoku was friends with Koji Hotei from way back in elementary school. Back then before the Skywall tragedy, the two had expressed their interests in politics and wanted to change Japan. After Soichi Isurugi returned to Earth with the Pandora Box, Gentoku, in place of his father, was in the audience alongside Hokuto's and Seito's Prime Ministers Yoshiko Tajimi and Masakuni Mido during the INSET return ceremony until Isurugi, whom was unknowningly possessed by Evolto, activated the Pandora Box, triggering the Skywall to raise in Japan, dividing it into three regions, and exposing Gentoku, Tajimi and Mido with a blinding light.
Night Rogue Rises
- "My name is...Night Rogue."
- ―Gentoku reintroducing himself as Night Rogue to the newly found Faust members.[src]
In the seven years following the Skywall Disaster, Gentoku, with a changed personality and now the Director of the Touto Institute of Advanced Matter Physics, confronted his friend Hotei, whom is now the aide to Touto Prime Minister Taizan Himuro, at the Touto capital. Gentoku attempted to use his friendship with Hotei to convince him to change Prime Minister Taizan's mind about building a military force. Hotei, in a calm manner, told Gentoku to calm down and address Hotei by his title. Ignoring his friend's request, Gentoku pointed out that both Seito and Hokuto are building their military forces, which Hotei replied that Touto must maintain their peaceful negotiations through diplomatic efforts and added that a large purchase of Touto's budget was used in purchasing of Namba Heavy Industries' Guardian robots. Gentoku scoffed at the news and pointed out about rumors of a few Guardians disobeying their commanding officers, to which Hotei stated he has no knowledge of those rumors, and then told Gentoku adamantly that Touto will never enter the arms race, angering Gentoku to the point where he seized his friend by the collar and insulted him for making Touto as submissive as him. Preparing to punch Hotei, two Touto security officers barged in the room after heaing Gentoku's raised voice and escorted him out of the capital, with Gentoku yelling at Hotei for ignoring him.
That night at the Karaoke Lounge Maneki Neko, Gentoku's place of refuge whenever he feels overwhelmed, he paid for one hour alone in a room, but changed his mind to three hours with unlimited drinks and the bill sent to the Touto Institute as research expenses. The cashier broadcast it out loud, which Gentoku told him not to do that, and asked the cashier politely for a strawberry parfait. For a while, Gentoku looked over the list of songs with a maraca near his head until he stopped, placing the musical instrument down and leaned back against the chair thinking aloud how Touto should deal with Hokuto and Seito. He then received a call from a worker at the Touto Institute that Takumi Katsuragi was performing in illegal human experimentation. Remembering being confronted by Katsuragi with a proposal to inject the mysterious Nebula gas into humans, Gentoku had an epiphany, but told to worker he'll be right there and finished his parfait before leaving the room.
Before Katsuragi could begin his illegal experiment, Gentoku lead a squad of Touto security officers into Katsuragi's lab and arrested all the researchers whom were part of the unauthorized experiment, and he watched two officers drag Katsuragi out of the lab, hearing Katsuragi pleading to start the experiment. After Katsuragi and the researchers were fired, Gentoku was heading home for the night until he received a call from Hotei. Hotei asked about the incident, and Gentoku assured him it's been resolved until Gentoku asked Hotei if he thought Gentoku had a part in Katsuragi's ceased illegal experiment. Hotei assured Gentoku he doesn't believe he had a part in it, and Gentoku asked him if he remembered Gentoku's plan to become leader of Japan before the Skywall Tragedy, to which Hotei told Gentoku he has become a different person since his exposure to the light from the Pandora Box before hanging up. Cursing Hotei's claim, Gentoku stated to himself it is Japan that has changed, and decided he can't entrust Touto to his father or Hotei.
A couple of days later, Gentoku confronted Katsuragi at a grocery store, telling the former employee he's come to scout for him. Katsuragi doesn't believe Gentoku as he was the one to fire him, but Gentoku told Katsuragi he did it to keep him out of jail. As Katsuragi accepted his offer, Gentoku brought Katsuragi to the Namba Heavy Industries Integrated Technology Development Institute, revealing to Katsuragi of an underground organization sponsored by the president of Namba Heavy Industries Ltd. Juzaburo Namba, and offer him to join it and allow him to continue his human experimentations, so he can help Gentoku and the organization to create the ultimate defense system to protect Touto and bring peace to all of Japan as he lead Katsuragi down to a lab with a vat container and equipment for administering the Nebula gas. Gentoku then reminded Katsuragi of his claim that science can create the future, offering Katsuragi the chance to show him before introducing Katsuragi to his new assistants Takahasi and Matsui. Brushing them aside to head toward a computer with his Nebula gas data, Katsuragi asked Gentoku if he can being the research now, to which Gentoku said yes.
In several months well into Katsuragi's research on the Nebula gas' effect on humans, Gentoku watched as Katsuragi administered a dosage of the gas to a human subject, but resulted in the human turning into a strange creature and breaking out of the vat, attacking the researchers as Katsuragi told them to run. Gentoku headed upstairs in an attempt to utilize a strange gun, until a man stopped him and took the gun himself, firing at the creature with one shot, causing the creature to revert back to normal. The man shouted "Bravo!" as Gentoku realized he was Soichi Isurugi, the astronaut whom found the Pandora Box and retrieved it to Earth. Evolto, utilizing Soichi's identity, introduced himself to Gentoku as he placed the gun on top of its container and headed down, telling Katsuragi that adjusting the dosage for the Nebula gas administration isn't easy before adding his own calculations to make the dosage safe for administration. After ordering Katsuragi to follow the newly inputted numbers, Gentoku asked him why he was here, which Evolto revealed he worked for Namba, and said he was told by Namba to offer his assistance to Gentoku, Katsuragi and the researchers with their impending experiments. Evolto also mentioned he's the only one who knows full well about the Pandora Box, but Gentoku assured him this research has nothing to do with the box, so Evolto cut to the chase, revealing that he knows what Katsuragi was building isn't a defense system, but the ultimate biological weapon, and that he has plans to use the box to rule all of Japan, which shocked Gentoku. Evolto proposed he could become his right-hand man, but Gentoku doesn't trust him, which lead to Evolto's second proposal: offering Gentoku the power he seeks, and compared Gentoku to Dr. Faust, a scholar whom made a deal with the devil to obtain power. Gentoku asked Evolto that he wants him to sell his soul and retorted by comparing Evolto as Mephistopheles, a demon whom wanted ultimate power. Evolto told Gentoku he'll see soon before exiting the lab, leaving Gentoku conflicted and angered.
At sunset, Gentoku stood on a rooftop where he and Hotei used to hang out, viewing the Skywall and its red light. He remembered a pact he made with Hotei to change Japan into a better country before they left to sing, joking around about Gentoku's tone-deaf voice. Gentoku then proceeded to the Karaoke Lounge Maneki Neko, sitting alone in a room still conflicted in his thoughts until Hotei arrived, whom was also conflicted, and expected Gentoku would come to the lounge and sing whenever he was struggling with something. Gentoku asked Hotei why he was there, to which Hotei revealed he wanted to sing as well. Soon, both friends were singing for hours until moonlight shined over the city. As they were finished, Hotei asked Gentoku what he wanted Japan to become now, to which Gentoku stated he wants Japan to become a strong and independent country that's fearless. Upset, Hotei told Gentoku he's still the same altered person after the SKywall tragedy, and Gentoku pointed out that Hotei wanted the same thing as well, but Hotei told Gentoku he's different from before, that he wants Touto to steer clear of Hokuto and Seito's quarrel over the Pandora Box, and that Gentoku's ambitions will lead to despair and destruction for Touto. Angered, Gentoku pointed out that their peaceful debates won't work with any other governments, but Hotei remains adamant it will and revealed to Gentoku that his father appointed Hotei as his successor, petrifying Gentoku as Hotei announced his clarity before leaving the lounge and announced he will change Japan.
Returning to the Namba Heavy Industries' Institute the following day, Gentoku's confliction has risen, asking himself why Hotei was appointed his father's successor while walking toward the basement until a body fell in front of him. Stopping dead in his tracks, Gentoku saw it was Hotei, forcing him to rush to his friend and try to wake him, but Evolto appeared, announcing to Gentoku Hotei's been dead for a while. Realizing Evolto killed Hotei, Gentoku seized him and demanded to know why he killed him, but Evolto punched him hard in the gut, forcing Gentoku to fall on his knees. Evolto deemed it was Gentoku's wish as he brushed his jacket. Shaking with horror, Gentoku then found clarity and looked up at Evolto with a malicious smile, deciding it's time to make a deal with the devil. Gentoku rose up and walked over his former friend's body and proceeded to the lab while Evolto stood back laughing at Gentoku's newfound resolve.
Approaching before the scientists and Katsuragi, Gentoku announced that from this day on their organization shall be called Faust, deeming despite that the people may view them as devils with their hands in blood, it will be them who will steer Japan into the country it should be. All the researchers and Katsuragi moved closer toward Gentoku, whom asked them to lend him their power as the researchers began to chant "Faust". Turning his gaze to the Transteam Gun's container, Gentoku smashed the glass with his fist, cutting it in the process and pulled out the gun and Bat Fullbottle. As he shook the bottle and inserted it into the gun, Gentoku told the Faust researchers that his blood now flows freely with his new ambitions and announced he has been reborn before transforming with the Transteam System into a bat-themed being, naming himself Night Rogue.
Within three years following Faust's founding, he was promoted to Hotei's position as aide to the Prime Minister of Touto, overseeing research of the Pandora Box. In his time as Night Rogue, he oversaw the human experimentations, including the one that appeared in Sento Kiryu's mostly forgotten memories from before his escape, sitting atop a throne. According to Gentoku himself, the reason behind these experiments is to accomplish one of Faust's objectives: to create the "Ultimate Lifeform."
Prelude to Build & Ryuga's escape
In the present day, Gentoku and his assistant Nariaki Utsumi were being interviewed by journalist Sawa Takigawa. In the interview, he recalls the Skywall Tragedy, and stated the Institute's objective is to deciphering the Pandora Box before foreign countries attempt to seize any of the current three regions. He then spots Sento approaching the vault containing the Pandora Box. Nariaki told Gentoku about Sento being a research applicant and his high test results, which impressed Gentoku. Sawa regains his attention by asking about multiple incident reports of people being attacked by creatures called Smash and the mysterious hero called Kamen Rider. He attempts to seduce her, which she didn't notice until he was leading her towards the lobby exit.
The next day, Gentoku accepts Sento into the Institute, with the task of analyzing the Pandora Box, which he believes is capable of producing energy that dwarfs nuclear energy itself. He then asks Sento about his knowledge of the Skywall tragedy, who then stated it was caused by the Pandora Box when it emitted a bright light, and Gentoku stated that same light also exposed people, changing their behaviors which lead into Japan divided into three countries. He was directed to the news where he and Sento learned of the criminal Ryuga Banjo escaped from prison. Gentoku told Sento he was responsible for the murder of one of Institute's researchers, Takumi Katsuragi. He was amazed as how Ryuga was able to escape a group of Guardian robots.
After Sento's battle with the Strong Smash, Gentoku, with Utsumi and several Touto military forces with Guardians, arrived and demand Sento, as Build, to turn Ryuga over to them. As the forces advance of Ryuga, Sento activates his Machine Builder and escapes with Ryuga, which forces Gentoku to capture them dead or alive. Utsumi attempts to reason with him, but Gentoku silences him and deem them unnecessary for the current stage of their plan. During the chase, Gentoku turns into Night Rogue and spies on Sento and Ryuga driving by the Skywall, stating the war has begun.
The Burn Smash incident
In order to flush out Ryuga, Night Rogue took his fiance Kasumi Ogura and brought her to Faust's lair, planning to turn her into a Smash. He found her phone ringing, with Ryuga on the other line, and answered it, letting Ryuga listen in horror as Faust scientists prepped Kasumi for the Nebula gas injection. He heads back to his chair and tells an infuriated Ryuga he will let him meet her once the infusion is complete and hangs up.
Back at the Institute, Gentoku and few researchers watch the news as the government declared Sento's alter ego Kamen Rider Build as a wanted man and displayed footage of Build attacking Guardians, which was a trap set by Faust. He told Sento the dangers of becoming a fugitive by opposing the government. After Sento left, Gentoku heads out and turns to Night Rogue, letting Kasumi, now the Burn Smash, loose back at her apartment complex. As Ryuga reaches the building, Kasumi attacks, and Rogue, in a mist form as a spectator, told Ryuga he kept his word, reintroducing his fiance, now a Smash, to her love. He watches as Kasumi attacks Ryuga until Sento appears and prepares to fight until Ryuga told him the Smash is his fiance. Solidifying himself, Rogue introduces himself to Sento, who turns into his HarinezumiTank Form while enraged and attacks, but Rogue has the upper hand as he told Sento he can't win with a random FullBottle.
As the Burn Smash attacks, Ryuga pleads with Sento to not attack her, but Sento assures him she will return to normal once the Smash element's been extracted from her body. Rejoining the battle, Rogue unveiled a horrifying truth: Kasumi's body was too weak to support the element, and removing it will cause to body to disintegrate. While Sento continues to attack and Ryuga shields Kasumi, Rogue noticed how Kasumi attacked herself rather than attack Ryuga from behind, realizing her conscious hasn't fully disappear. Sensing this, he watches as Sento turns into RabbitSoujiki Form to force her to use up all her fire power and turn into GorillaMond Form to use its Vortex Finish to separate Kasumi from the Burn Smash long enough for Ryuga to say goodbye before she disintegrated. He then leaves, having seen enough.
Blood Stalk Reemerges
At the Touto Government capital, Gentoku watched his father, Taizan, also the Prime Minister, in his monthly meeting with Hokuto's Prime Minister Tajimi and Seito's Mido. Taizan asks how both countries are since the Skywall tragedy: Yoshiko presents progress for Hokuto's growth in parental support and agricultural resources, and Masakuni stats his country is sending out their young in order to restore their fragile economy, which lead Taizan to believe both Prime Ministers have no interest in reuniting with Touto to make Japan whole again. Masakuni told him it would be difficult as the Skywall cut off their resources and Yoshiko stated it will remain so until they find a way to deal with the wall. Taizan agrees and concludes the meeting. Gentoku doesn't believe them, as he told his father Hokuto's militia is increasing to match Touto's and proposes expanding their militia, but his father disagrees, stating what they have now is only for self-defense. Referring him as "father" also angers Taizan and repeats himself to refer to him as Prime Minister; he then demands to know the progress on locating Kamen Rider Build, which Gentoku told him they were unsuccessful. Taizan tells Gentoku to find the Kamen Rider quickly, and in doing so would soothe the fear that's been cast over Touto.
At the Institute, Sento asks Gentoku and Utsumi about a man named Masahiro Nabeshima and him being possibly connected to Katsumi's murder, to which Gentoku lied about not knowing him. Sento then switches topic and asked what kind of person Katsumi was, and Gentoku told him Katsumi was a genius and in charge of the research on the Pandora Box. He also told Sento Katsumi was called the "Demon Scientist". After Sento left, Gentoku turned into Night Rogue and approached Nabeshima, telling him he has his wife and daughter hostage in Seito. In cooperation, he forced Nabeshima to answer his cell phone, with Ryuga on the other line and to tell him about his involvement with the organization Faust and his family being hostage in the sixth District of Seito. After hanging up, he pleads with Rogue to release his family, but Rogue drags him back to Faust's lair and have him prepared for the Nebula gas infusion, praising Nabeshima's work as a covert operative before he became the Mirage Smash. Later that night, Gentoku sits in a car while examining the Rocket Fullbottle, sensing that Blood Stalk has finally made his move.
Brought back by Stalk, Gentoku had the Faust scientists administer the Nebula gas into Nabeshima again, but he broke free and turns into an incomplete Square Smash. Gentoku theorizes a second dose of the Smash element increases the subject's destructive power before the incomplete Smash attacked him. However, Gentoku overpowers it and and brings it down with his Transteam gun while adhering himself to the lair's roof and jumping down to deliver a finishing punch. He told the Smash that Faust's main objective was to create the ultimate life form and ponders the possibility of administering another dosage to an already experimented Smash.
The next day at the Institute, Sento presents a recording of the Skywall tragedy to Gentoku and Utsumi. Utsumi demands to know where Sento retrieved the footage, but Gentoku assures him it's fine before vacating the main hall to leave him, Utsumi and Sento alone. Sento shows a modified footage by removing the light cast after the astronaut responsible for the Skywall tragedy, revealing that the Pandora Box had six, colored matching panels, two red, two blue and two green, that gave it a dual structure before they were separated. Sento surmises that the two green panels should be somewhere in Touto, but Gentoku told him there are no panels. Sento demands there are two green panels before Gentoku becomes enraged and ceases talking to him, but Sento surmises the possibility of the panels being stolen by an underground organization named Faust.
Ustumi seizes Sento, but Gentoku stays his hand and asks Sento where he heard the name Faust, then concedes to the panels actually exist but were stolen three years ago, and that by concealing the truth would prevent mass hysteria to the public and that both Seito and Hokuto are after the Pandora Box for their own nefarious purposes. Sento asks how Faust got past Touto's security and Gentouk mentions the possibility of a traitor and shows Sento the astronaut running towards the box. Returning to the lair, Gentoku places the Rocket Fullbottle in one of the green panels attatched to a frame beside his chair, asking Stalk as he returned why he didn't kill Sento. Stalk assures him his strategy-making habit always appear beneficial and that their plan is going according, even by sparing Sento. Tatsuya Kishida, a person who from Sento's past, and placed him in the containment chamber, ready to administer the Nebula gas into him. Rogue asks Stalk what he needs Tatsuya for, and Stalk replies to see if he will be a worthy opponent for Build. By daylight, Tatsuya, now a Press Hazard, approaches the Institute, but Gentoku was prepared with Touto officers and Guardians. Watching the conflict from a bridge with Utsumi, Gentoku orders them to keep the Smash away from the building before tossing the radio to Utsumi. When Build enter the scene, Gentoku became intrigued and found Build's timing convenient, telling Utsumi to give the order to kill Build and the Smash. Before it could be carried out, Ryuga arrives and diverts the Touto officers and Guardians. Seeing Ryuga distracting the Institute's Gentoku demands he want Ryuga to be captured and brought to him alive. His plan, however, failed as Ryuga Build flee the scene with the Smash, and Gentoku walks away in irritation.Back at Faust's lair the following night, Night Rogue was puzzled as Stalk return with,
At night, Gentoku returns to the Faust lair as Rogue, observing over the Press Hazard's second dose of Nebula gas. He tells Stalk all his plan did was raise Build's Hazard Level and demands to know his true motives, to which Stalk replies he hungers for strength, and to allow Build to learn more about himself before proceeding to the next stage. The next, Gentoku finds Sento at the Institute and acted amazed by his current research on the Skywall. He tells him of a property the wall possesses: the ability to emit a gas not native to Earth, which Katsuragi coined it "Nebula Gas". He tells Utsumi to bring up Katsuragi's research on the extraterrestrial gas to show it to Sento, which was part of Gentoku's current scheme as he gaze Sento with satisfaction. Later that night at the Touto Government building, Gentoku calls Stalk and assures him Sento's acquisition of the Nebula Gas file. He states Sento can even surpass Stalk in scientific endeavors.
Clash with Stalk
Reaching the Skyroad to Hokuto, Rogue dispatched several Faust Guardians to subdue Hokuto refuges and the contractor to the passageway. He demand Build to show himself or he'll have the refugees and criminal killed on the spot. Sento turns into Build and engages Rogue while Ryuga, dressed in a clown attire, dealt with the Guardians. Rogue gained the upper hand with his bat-like abilities and his Steam Blade's Ice and Elec Steam attacks, backing Build into a corner. He turned to Ryuga, who has defeated the Guardians, and prepared to attack him until Build sneak attacked him and drove away with Ryuga on the Machine Builder. Gaining distance, Rogue ordered Stalk to stop them, whom obliges by placing the Rocket FullBottle, which was given to him by Rogue, and performed a Steam Attack. However, to Rogue's surprise, the attack rebounded and almost hit him instead. When the smoke clears, Rogue knew Build and Ryuga have disappeared in the passageway and cursed Stalk who pursued them on his own.That night, Gentoku returned to the Touto government building, watching a meeting between his father, Taijimi and Mido. Taijimi demanded to know why Build and the Smash were spotted in Hokuto, which she believed would cause massive hysteria to the Hokuto denizens. She also made a claim that Touto was responsible for their appearance, followed by Mido claiming Touto harnessed them as weapons. Taizan stated their claims as nonsense, and as Taijimi ignores him, Gentoku intervened, assured her the matter will be dealt with, and told her he won't let her seek any reason for Hokuto to go to war with Touto, and cuts off their transmissions as Taijimi attempted to lie about not wanting war. Taizan questioned Gentoku's reason to end the meeting, which lead to Gentoku being fed up to his father's naivety, claiming Taijimi and Mido want to invade Touto and they need an army, to which Taizan finds it surprising to hear his son's claim for an army once more. Gentoku also stated the reason for his father's naivety was due to the fact that he wasn't bathed by the Pandora Box's light during the Skywall tragedy and that people who were changed. Taizan told his son he's the one who has changed and they should focus on stabilizing their economy rather than focus on war.
Returning to Faust's backup lair, Gentoku questioned Stalk for his methods regarding Build's fight with a Smash in Hokuto. Stalk passes off the claim and reminds him of the data Katsuragi hidden in Hokuto, data that can be utilize to not only upgrade the Rider System, but to militarize it as well. The next day, he learns of Sento and Ryuga's plan to return to Touto with Katsuragi's mother, Kyoka, who they believe knows where her son's hidden data was located. As Night Rogue, he intercepted Kyoka's car and knocks her out, carrying her over his shoulder and walking away as Build dispatches the Faust Guardians. At Faust's lair, he cancels his transformation and interrogates Kyoka, assuring her of her son's involvement with creating Faust. He demands the location of her son's hidden data, and if she cooperates he would give her the last letter Takumi wrote to her but never sent. She agrees, hand him a badge and key, telling him the data's in a safe deposit box at the Touto Bank with its number. To her shock she found out she was deceived as the letter was just a blank paper, and Gentoku told her her son wasn't the type of person to show gratitude to their own parents, provoking her to hit him, but Utsumi grabbed her arm. Gentoku orders the Faust technicians to administer the Smash element and send her back to Hokuto, as well as wiping her memory of him.
While Build and Ryuga learned of Kyoka's transformation into a Strong Smash Hazard, Gentoku and Utusmi head to the Touto Bank and open the deposit box. To their surprise, they find a letter by Takumi in it, stating whomever opened it is untrustworthy. Gentoku realized Kyoka was suspicious of him from the get-go. Utsumi received a call from Stalk and hands it to Gentoku, learning Sento and Ryuga have found the location of the hidden data: the abandoned Namba Heavy Industries Integrated Sciences Laboratory. After heading there and seeing Build and Ryuga engage Stalk for the flash drive containing the data, Gentoku turns into Night Rogue and attacks Build. He orders Stalk to leave with the data, but Ryuga engages Stalk as Rogue fights Build. Rogue and Build are on par until Build turns into GorrilaRocket form and pushes Rogue back. Rogue claims Build can't with like that and forms his Steam Rifle while Build turns into his RocketPanda Best Mach and beats him with a Vortex Finish. Intrigued, Rogue reengages with Build until he saw Stalk toss the drive to Ryuga. Shocked, he attempted to attack Ryuga until Stalk intervened, holding him at bay and allowing Build and Ryuga to leave. Pointing his Transteam Gun at Stalk, Rogue demanded to know his scheme, to which Stalk assured him they don't need the drive, just the tools the data can create as he believes both Sento and Ryuga can do it. However, Rogue became suspicious of Stalk, wondering what kind of scheme he has in store.
Faust Invades Touto Institute
While taking a hot bath at one of Touto's bathing facilities, Gentoku is approached by Juzaburo Namba, the president of Namba Heavy Industries, and also the benefactor of Faust. Namba praised the bathing facility as he bathes himself in the refreshing hot water, telling Gentoku he used to look forward to this place as a child. He then asked Gentoku if he was able to convince his father of amassing an army, to which Gentoku tells him not yet. Namba has doubts of Gentoku's assurance, reminding him of all the money he's placed in Faust and believing the Rider System will revolutionize the world as a weapon, and asks him if he should turn to either Hokuto or Seito. Gentoku tells him not to, but Namba stated he will if Gentoku doesn't give him the Rider System. Showing his fear of Namba, Gentoku conceded.
Later on, Gentoku learned that Misora Isurugi and Ryuga are exploring the streets in disguise. He sent several Faust Guardians to retrieve them, but Ryuga takes them on while Misora heads to safety and informs Sento of their location. Gentoku, as Rogue, appears and takes her phone. Rogue informs her he's let her free up until this point, intending to bring her back to Faust. He advances to Misora, backing her to a wall and made her faint due to his fearful quality. As she falls to the floor, Ryuga appears and attempts to fight Rogue, but becomes overpowered. Before he could continue, Blood Stalk appears between Ryuga and Rogue, telling Rogue to not act behind his back and allowing Ryuga to leave with Misora. As Rogue attempted to pursue, Stalk gestured him not to, and both Faust members stare at each other with annoyance. In secret, Rogue dispatch a few more Faust Guardians to intercept Ryuga and an unconscious Misora, but are quickly destroyed by Build NinninComic.
Returning to their backup lair, Stalk learns of Namba's deadline for the Rider System. Cancelling his transformation, Gentoku vowed to make sure the Rider System will never be distributed to other countries. Stalk asked him how plans to do that, and Gentoku told him with no hesitation: steal the Pandora Box from the Touto Institute to ignite a war between the three countries. He also believed in doing so will finally push his father into action, and turns to the stairs to see Shingo Kuwata, one of the Institute's researchers. His plan involves Kuwata to infiltrate the Institute and lure Sento out, so Eita Kawai, another researcher, could deactivate the security lock for the Touto Institute. Kawai calls Gentoku, whom's still in the backup lair, and confirms him of his completed objective. Delighted, Gentoku gives the word to carry out the plan.
The next phase of the plan involves Stalk entering the building and as he approaches the floor where the three Prime Ministers and the Pandora Box are, he signals Kawai to trap them, Utsumi and the box in an energy barrier on the eleventh floor, while Gentoku remains outside in charge of a response team and observing the Institute's camera system. Hearing the Institute's security being dismantled by both the Faust and Touto turned Faust Guardians, Gentoku orders them to protect his father no matter what over the radio. To his surprise, he saw Stalk shoot the cameras as he made it to the eleventh floor. He wonders if Stalk plans to steal the box for himself and sneaks his way to the Institute's roof. Holding out his Transteam Gun, he finds Stalk and told him this isn't the escape route they had planned. Stalk attempts to lie about getting lost, but Gentoku sees through it as he notes Stalk's scheme to shoot out the security cameras to cover his tracks. He places his Bat FullBottle in the gun and transforms into Night Rogue, asking him to handover the box, to which Stalk asks if he refuses.
Annoyed, Rogue engages Stalk, stating he won't forgive traitors until Ryuga, with a few cuts and bruises, interrupted their fight. Stalk asks him what happened to Press Smash Hazard, which was Kawai transformed by Stalk, and Ryuga stated he beat it but couldn't extract the Smash element without an empty Bottle. Rogue was shocked Ryuga managed to defeat a Smash without a Rider System, while Stalk became amazed. He gazes on as Ryuga engages Stalk, only to be quickly defeated as Ryuga's fight with the Smash left him scathed until Build HawkGatling arrives to assist him, forcing Rogue to assist Stalk. Rogue fights Build while Stalk engages Ryuga once again. Rogue is pushed by Build's LionCleaner and FireHedgehog forms, but catches Build off-guard as Build stops his attack on Rogue as he spots Stalk gaining the upper hand on Ryuga and attack him. While Rogue attacks Build, Stalk inserts his Cobra Fullbottle in his Steam Rifle and executes a Steam Shot at both Rogue and Build, knocking Rogue to a wall and not only cancelling Build's transformation but force him to drop the majority of his Fullbottle collection as well. As Rogue recovers, Stalk took the Pandora Box and leaves, angering Rogue. He spots Sento's Fullbottles exposed and plans to take them, knocking Sento aside as he attempts to stop him. He places the Ninja, Comic, Hawk, Gatling, Harinezumi, Shoubousha, Panda and Rocket Fullbottles on the panel from Faust's compromised lair near the Skywall. As he retrieves the Gorilla and Diamond bottles, Rogue made a jab and laugh as how Build used them to kill Ryuga's late girlfriend Kasumi. Sento rises and tackles Rogue as he takes the Lock, Kaizoku and Soujiki bottles, allowing Ryuga enough time to place the Dragon Fullbottle in the Cross-Z Dragon, telling it to give it to Sento.
Empowered, the Cross-Z Dragon attacks Rogue and retrieves the Lock bottle, giving it and the Dragon bottle to Sento, utilizing them to turn into Build KeyDragon. Build engages and overpowers Rogue, whom wonders what kind of power Build now possesses. Build tells Rogue he can't lose as Ryuga entrusts him the Dragon bottle and performs a Vortex Finish, forcing Rogue to retreat after vowing to make Build pay. However, he reemerges after Build intercepts Stalk and attack him from behind. Rogue asks Stalk where he plans to take the Pandora Box as a dozen Faust Guardians surround them, their rifles pointing at Stalk. Stalk tells him to their lair as he offers the box. Rogue takes the box, whom accepts it and takes the Rabbit, Tank and Lion bottle from an unconscious Sento. As he leaves, Sento wakes up and grabs his leg, demanding his bottle back before Rogue kicks him in the face, then proceeded to walk away laughing. Cancelling his transformation, he returns to the Institute with a smile on his face until he spotted an ambulance and his father, who has just had a heart attack, being carried out on a gurney by Utsumi and paramedics. He runs over and asks what happened, but Taizan places him as the acting Prime Minister until he recovers. Upon hearing his new position, Gentoku smiles maliciously after all the events that has transpired up to this moment.
Rise of Cross-Z
At the Touto Government capital, Gentoku calls a meeting with Tajimi and Mido. Mido asks Gentoku of his father, who tells him he must rest for now, leaving him as acting Prime Minister of Touto. Tajimi demands to know if he has any relations with Faust, but Gentoku's one step ahead, claiming if she suspects if Touto has an alliance with Faust and retort if Hokuto allied with Faust, offending Tajimi. Mido tells them both there's no point in pointing fingers at one another as they leave the Faust investigation and retrieval of the Pandora Box to Touto, but he claims both Seito and Hokuto won't wait forever. Gentoku assures them they will do their best before they cut off transmission. Stalk appears, questioning Gentoku's facade. Utsumi, who watched the meeting from afar, approached Stalk and demands to know why he's in the capital before Stalk shoved him aside. Gentoku tells him to leave, forcing Stalk to joke lightly about his current position making him a cold person. As he sat down, Stalk demands to know why Gentoku has placed the Pandora Box in a secure location without Stalk's knowledge, and Gentoku claims to share the location if Stalk acts more loyal to him. To their surprise, two Touto security officers enter the room, preparing to accost Stalk, but Stalk kills them both. Stalk tells Gentoku Faust doesn't belong to him.
The next day, Gentoku decides to flush out Sento and Ryuga, placing a false eyewitness of a Smash at an abandoned factory. Sento and Ryuga take the bait, allowing Gentoku, as Night Rogue, and four Faust Guardians to corner them. Rogue demands Sento to hand over the last two Fullbottles they have, but they refuse as Sento turns into Build KeyDragon, much to Ryuga's annoyance as he wanted to try transforming into a Kamen Rider for the first time. Build engages Rogue as Ryuga deals with the Faust Guardians with little effort without his bottle, forcing him to take one of the Guardian's rifle. As Build overwhelms Rogue, the Dragon bottle begins to overwhelm Build, encasing him in blue fire until it cancels his transformation. Rogue rises and states to hand him the bottles as Ryuga rushes to Sento's side, but Stalk appears, commending Rogue for his deception. As Sento and Ryuga argue over allowing Ryuga to try and transform, Stalk states he's there to help them, but Ryuga doesn't buy it as he believes Stalk is Katsuragi and attempts to place the Dragon bottle in the Cross-Z Dragon in its Adaptor mode, but fails. As both Stalk and Sento became embarrassed, Stalk tells them to leave and throws a chair at Rogue, who attempts to shoot them. Angered, Rogue asks Stalk what's he doing, but Stalk leaves, with Rogue departing in a different direction in anger.
At night, Gentoku met up with Namba at a fishing village, praising Gentoku for both his position at the Prime Minister's chair and obtaining the Pandora Box. Gentoku assures him every Faust scheme will go on unnoticed, and Namba asks him they need three more Fullbottles for the Pandora Box, to which Gentoku states they need and assures him he will retrieve them before leaving. Later on, he receives word from Namba that Sawa, whom was a spy for Faust, has been compromised. They decided to cast her aside and abducted her into Faust's backup lair, administered the Nebula gas and turned her into an Octopus Smash, catching her transformation on her camera video for Sento. As Rogue, he tells Sento he plans to set the Octopus Smash loose on the city and he'll be waiting for him. At daylight, Rogue watches from afar as Build, in his KeyDragon Best Mach, take on the Octopus Smash, waiting for the Dragon bottle to overwhelm him once more. After Sento falls down from the cancelled transformation, Rogue made his move and tells the Smash to stop. He grabs Sento and demands him to hand over the bottles, until Ryuga arrives. Sento breaks free and throws the Dragon and Lock bottles at Ryuga, angering Rogue, who backhands Sento and orders the Smash to attack Ryuga. Rogue commends Ryuga for taking on the Smash as he prepares his Steam Rifle, but Sento gets in the way. Fed up, Rogue takes the Build Driver and knocks him aside, stating he's done utilizing him for Faust's purposes. As he advances toward Sento with his rifle pointing at him, Ryuga takes the driver from him and places it on, now in complete sync with the Cross-Z Dragon and finally succeeds transforming into Kamen Rider Cross-Z, angering Rogue. After defeating the Octopus Smash, Cross-Z summons his weapon and engages Rogue, overpowering him before forcing him to retreat after unleashing a Lock Million Slash Finisher.
After learning Sawa's involvement with Faust and discovering the Pandora Box has been placed in a secure location from a recording of a conversation between Gentoku and Namba she made during her abduction, Sento and Ryuga head back to the Namba Heavy Industries Integrated Sciences Laboratory, after learning the laboratory has a hidden third basement, to investigate if the Pandora Box is there. Gentoku, as Night Rogue, stumble upon Sento and Ryuga in the third basement, and asks them to leave as he and four Faust Guardians walked down the stairs. Not obliging, Ryuga turns into Cross-Z and engages Rogue while the Guardians attempt to accost Sento, whom easily destroys them with the Drill Crusher. However, Rogue was prepared as he held is own and overpowers Cross-Z, stating his Hazard Level's still higher than Cross-Z, meaning he was previously defeated due to underestimating Cross-Z's power. He tells Cross-Z to not underestimate him as he knocks him to the ground with an Elec Steam attack, and the fallout knocks Sento down as well. Preparing to continue the fight, Stalk appears, asking Rogue if this is the place where the box is hidden. Rogue demands to know why Stalk came, to which Stalk replies, to Rogue's surprise, to fight him. As they fought, Stalk spots a newly paved wall and thrusts his Steam Blade in it to create a hole, exposing not only the Pandora Box, but the Fullbottles Rogue stole from Sento and the new Densya bottle. Rogue pushes Stalk away from the box and bottles, allowing Sento enough time to retrieve his bottles and transform with an additional Build Driver into Build KaizokuRessya. As Build intervenes in their fight, Cross-Z forces Stalk down the hall as Rogue and Build engage one another. Both fighters were on par until Rogue spots Stalk teleporting away with the Pandora Box, providing an opening for Build to strike him down with a Vortex Break, forcing Rogue to retreat and allowing Build to take Faust's panel as well.
At Faust's backup lair, Gentoku curses Stalk for his betrayal as Utsumi tends to his wounds. Namba appears, dissatisfied that Gentoku let Stalk steal the box. Gentoku apologizes, and to his surprise Namba let bygones be bygones, but addresses that actions must be taken since it was stolen from their abandoned lab, turning to Utsumi. Gentoku learns of Naba's countermeasure: have the Touto government to destroy Faust once and for all. The next day, Touto's operation to eradicate Faust places it at a dam, with Gentoku in charge, to keep his cover intact. Few minutes later after a Touto squad enter the dam, an imposter Night Rogue, which was Utsumi, emerged from the entrance, claiming he's the creator of Faust. To keep the ruse up, Gentoku orders a squad of Touto Guardians to open fire at Utsumi, but their weapons made no dent as Utsumi shoots the Guardians down before heading up the dam. As Utsumi lands at the top, he engages Build KaizokuRessya and is quickly defeated, cancelling his transformation for the news to see Utsumi as the creator of Faust, unaware he's a scapegoat. Gentoku notices the news media bought the con, and notices Build stopping Utsumi from exposing himself with a Fullbottle in a suicide attempt, forcing Utsumi to run. Gentoku pursues with two Touto officers beside him until they caught up with Utsumi and Build. As Utsumi attempts to tell Build something, Gentoku shoots Utsumi's shoulder, causing him to fall off the bridge and into the running waters. He hands the rifle to one of the officers and leaves. Later on, Gentoku made an address on the news of Utsumi's betrayal as an act of fear and the defeat of Faust all to keep the ruse up and states he will protect Touto, completely unaware that Blood Stalk saved Utsumi.
Blood Stalk Exposed & Gentoku's Cover Blown
- "Isurugi told me..."Takumi Katsuragi is alive...in a different form." It's you, Sento Kiryu. You're the demon scientist...Takumi Katsuragi!"
- ―Gentoku reveals Sento's identity.[src]
The following day at Touto Institutes, Gentoku calls Sento in a room, telling him that Pandora Box is in one of Namba Heavy Industries' storage facilities, but they can't act without concrete proof and asks Sento for his wisdom, so he can have Sento and Ryuga retrieve the box for him.Having himself been exposed as Blood Stalk, Soichi Isurugi revealed to Sento that the true Night Rogue was Gentoku Himuro.
During the Enigma crisis which saw the World of Build briefly docked with the World of Ex-Aid, Gentoku met with Sento at the Touto Institute of Advanced Matter Physics, where he revealed to him the history of the calamity's instigator, Kaisei Mogami. Soon after, Mogami's plot to combine the two worlds was thwarted by Build.
Knowing Sento and Ryuga were successful in retrieving the Pandora Box, Gentoku sent a Touto squad to break into nascita days after the Enigma crisis, informing the squad it was an anonymous tip. Inside the cafe, however, he found no trace of the box or both Kamen Riders, as he was unaware of Sento and Misora watching him from afar after establishing a hiding place in an abandoned warehouse. Gentoku opened the refrigerator door, knowing there's a secret path to a basement, yet was shocked to see it was an ordinary fridge, agitating him. Receiving a call from Sento, Gentoku headed down to the Touto Institute's parking lot to see Sento with the concealed Pandora Box. Asking him what they needed to talk about, Sento told Gentoku to drop the act as he unveils the box and calls Gentoku Night Rogue. No longer able to keep the ruse, Gentoku stated he'd wished to keep his identity as Rogue a until Sento completed some form of project, which is what Isurugi wanted as well. Sento asked him what they meant, but Gentoku told him he'll know once he looks up the word "Sclash" in Katsuragi's research data, and added that Faust main objective was to utilize the Rider System for militaristic endeavors, all to win the inevitable war between the three regions. Watch from aside, Ryuga loses his temper and engages Gentoku, forcing to transform into Rogue and gain the upper hand. As he held Ryuga in an arm lock, he spots a fallen recorder from Ryuga's jacket. Surprised, Rogue orders Sento to toss his recorder aside as well. Ryuga breaks loose, transforms into Cross-Z and reengages Rogue. Noticing Cross-Z's new growth in strength, Rogue decided to cut loose and show his full power, generating a pair of bat wings and easily defeats Cross-Z. As Rogue approaches the defeated Ryuga, Sento turns into Build LionComic Trial Form and uses his Nipontou's Disappearing Technique for him and Ryuga to leave. Satisfied he now has the box, Rogue turns toward it but finds out it was a hologram, a trap to confirm his identity as Rogue. Angered, Rogue curses the Riders and kicks the trolley before turning around to see an amused Isurugi approaching him.
At Isurugi's request, Gentoku informs his father of the Pandora Box's current location, the person who has it and having him arrange a meeting with Sento to return the box to the Touto government, all part of a scheme to retrieve the box. After his father arranged their plan, Gentoku walks out of his father's hospital room and bumps into Isrurgi, whom asks Gentoku if he can trust him again. Cautious, Gentoku would consider trusting him if he doesn't have any hidden schemes in store. However, as their plan failed the next day, Gentoku heads to the Touto government and scowls Isurugi, demanding to know why he didn't take the box from Sento and Ryuga at the hospital. Isurugi, being funny, stated he had to do something important as he presents a cache of coffee beans to Gentoku, while in reality he snuck into nascita and made a copy of the Katsuragi's incomplete Sclash Driver and Sclashjelly blueprints. Furious, Gentoku knocks the cache from Isurugi's hand and grabs him by the collar, demanding to know if the whole thing was a trick, but Isurugi panicked as he doesn't like to have his jacket wrinkled. After Gentoku released his grip, Isurugi assures him they will retrieve the box and as compensation, he tells Gentoku a secret he only knows about Sento.
After learning of their hiding place, Gentoku arrived at the warehouse with two Touto officers and a over a dozen Guardians, finding Sento, Misora and Ryuga with the Pandora Box. As the Guardians advance, Sento turns into Build KaizokuRessya and Ryuga into Cross-Z, easily dispatching them, amusing Gentoku as he now knows the truth of Sento's origins. Gentoku turns into Night Rogue, shocking the two officers before he turned them into a Strong Smash Hazard and an Octopus Smash Hazard with his Steam Rifle's Devil Steam. As Cross-Z deals with the two Smash Hazards, Rogue told Build he doesn't belong on side against Faust. Confused, Build made the first move, telling Rogue he won't let him have the Pandora Box. They head outside to continue the fight, until Build spotted the Octopus Smash Hazard attacking Misora and kicked Rogue aside to launch a Kaizoku Densha with Cross-Z's Million Hits slash to destroy the Octopus Smash Hazard. Spotting an opening, Rogue attacks Build with his Steam Blade and disarms him, stating he's Build's opponent. Turing into LionCleaner, Build unleashes a Vortex Finish to gain the upper hand against Rogue, until he shoots Build with his Transteam Gun, claiming he will obtain the Pandora Box's power and rule Japan, and told Build that was what he used to want as well, confusing the rider before he turned into his RabbitTank Best Mach. Fed up, Rogue tells Build to reawaken and remember everything as he parried Build's Drill Crusher with his Steam Blade. Build told him to stop with his nonsense and uses a Vortex Break with the Rocket bottle, pushing rogue back. Unsatisfied with Sento's disregards of his words, Rogue unleashed his wings and took to the sky, attacking Build with aerial assaults. To his surprise, Build turns into a new form: RabbitTank Sparkling and destroyed Rogue's wings, and attacked him with a barrage assaults with his Drill Crusher blade mode and Nipontou, followed by shots from his Drill Crusher gun mode and HawkGatlinger. Build unleashes a Sparking Finish as Rogue created a new pair of wings and flew in to intercept, but became overpowerd by Build, sending him threw the warehouse with an explosion, forcing him out of his transformation.
As night fell, Sento and Ryuga, carrying an unconscious Misora, approached the injured Gentoku. Gentoku commended Sento's genius as he struggled to rise, until he heard his father's voice from behind. Gentoku turned to see Taizan being rolled in a wheelchair with Touto agents, shocked to find out Gentoku was part of Faust. Taizan scolded Gentoku for having no notions of his consequences, leaving Gentoku ashamed in front of his father. Taizan apologized to Sento and Ryuga for not knowing of his son's involvement with Faust, begging for their forgiveness. Moments later, Sento and Ryuga gave the Pandora Box back to Taizan, who assured them he will place it back in where it belonged and told Gentoku he will be dealt with later before leaving. As Gentoku was being escorted with two agents, Sento demanded to know what he meant by his claims. Gentoku told him he was informed by Isurugi that Katsuragi is indeed alive, but with a different face. As he approached Sento, Gentoku gave him a shocking revelation as he laughed maniacally: Sento is the demon scientist Takumi Katsuragi. Taro Satou, whom came for a job offer, unaware that it was a trap. As he saw Stalk, he got scared and attempted to leave, but Stalk threw a dagger in his back, killing him instantly. He then walked over to Taro's corpse and changed his face to Katsuragi's and headed over to Katsuragi to turn his face to Taro's. He switched Katsuragi's and Taro's clothes, dragged Katsuragi outside and into a car. As he waited for Ryuga to show up in response for a job, he called the local authorities and stated he saw a neighbor get stabbed and named Ryuga as the murderer.Ryuga refused to believe it, and Sento demanded proof. Gentoku reminded Sento of Isurugi's ability to alter a person's face to make that person look like an entirely different person, a power Isurugi obtained on Mars. He then recalled what Isurugi told him of the secret he mentioned a day ago to Sento and Ryuga: last year, Isurugi, as Blood Stalk, met with Katsuragi at his apartment, telling him he's quitting Faust. With no alternative, Stalk had a contingency in play as he knocked out Katsuragi:
After listening, Sento still found hard to believe he was Katsuragi, the person who co-created Faust and conducted human experiments to create the Smash. Gentoku added that Sento's amnesia was also Isurugi's doing. Sento remembered being administered the Nebula gas as Rogue and Stalk watched, but he stated to Gentoku he would've asked him for help if he really was Katsuragi, but Gentoku told him his mind was wiped before being injected with the Smash element. Sento asked how, and Gentoku told them a test subject only loses their memory up to a few hours before being injected, while telling Sento that Isurugi also possessed the power to wipe his mind completely before bringing him to the lab. Ryuga believed Gentoku as he surmised that Nabeshima's complete memory loss was also Isurugi's doing. Gentoku laughed and told Sento as he was Katsuragi his personality was the exact opposite of whom he is now: a person who scoffed at things like justice and would go to the extreme for his scientific ambitions. As he leaves, Gentoku promised he will return and when he does, Sento will be by his side once again.
Hokuto Invading Touto & Exile
The next day as he clears his stuff from the Prime Minister's office at the Touto government capital, Gentoku was told by a co-worker that his father has collapsed once more, unaware that Taizan was poisoned by Stalk. At night, Gentoku, still placed as acting Prime Minister, informed Tajimi and Mido that Touto has retrieved the Pandora Box. Mido applauds Gentoku, but Gentoku told both him and Tajimi that it's time to drop the facade and that the three of them each want the box's energy for their own selfish desires and control the world. Tajimi pretended not to acknowledge his claim, but Gentoku stated Hokuto's meager budget has sunken in military development, angering Tajimi. Gentoku proceeded to say that their ambitions that caused Japan to split into three region, and proposed a challenge to see whom should rule all of Japan before Mido and Tajimi cut off their transmissions, each of them pleased.
The next day, Gentoku learns of two Smash Hazards and a squad of Hokuto Guardians running amok in Touto and arrived, with a Touto security personal, just in time to see Sento and Ryuga having already taken care of them, but left puzzled as to why there are Hokuto Guardians and two Hokuto residents whom have been turned into Smash. Gentoku told Sento and Ryuga, whom were both shocked to see Gentoku still in power as the acting Prime Minister, that this is an invasion. When Sento asked what invasion, Gentoku told him that Hokuto has invaded Touto, an act of war.
Days into the war and a majority of Touto taken by Hokuto, Gentoku decided the war would be the perfect opportunity to utilized the Kamen Rider System as a weapon by having Touto forces storm into Nascita and take Sento and Ryuga. Having the forces bring both riders into the war room at the Touto Capital building where he saw Touto forces being decimated by Hokuto's, Gentoku readdressed the region's current dilemma with Hokuto claiming vast sectors and with Hokuto-produced Smash appearing in different areas as he brought the riders into the main office where the Pandora Box is. Gentoku then told Sento and Ryuga more about the box: that it had six panels with ten bottles each, making a total of sixty bottles, before Isurugi opened it during the Skywall Tragedy. Gentoku also believed that all the bottles, along with the six panels, can open the box. Ryuga was surprised to hear this, but Gentoku pointed out that the 40 not purified in Touto were somehow purified and those bottles and the four remaining panels were divided between Hokuto and Seito, and Sento surmised the the regions can't open the box until they've cooperated. Gentoku agreed but pointed out to Hokuto's declaration of war as a sign of conquest, and Seito will follow soon after.
As he sat down, Gentoku told the riders to protect the box from the two regions, meaning he wants them to serve Touto and participate in the war. Sento declined and was heading for the door, but Gentoku reminded him he set this in motion when he experimented with the Nebula gas on human subjects as Katsuragi, but Ryuga, in anger, told Gentoku he was the one to use it for evil. Gentoku then told them if they served and repel Hokuto's invasion, he will grant full pardons, meaning Ryuga can finally have his name cleared. Despite this, Sento still declined, forcing Gentoku to have Guardians and Touto officers pointing their rifles at them, stating they have no choice as he slapped a wrist band with GPS and transmitter onto Sento's and Ryuga's wrists. After failing to contact Sento hours after their departure, Gentoku contacted Ryuga, asking him where Sento was. Ryuga asked him why, and Gentoku stated he wanted to see if the Sclash Driver was finished. Surprised, Ryuga told him Sento built it, but he also said they can't use it. Remembering what Stalk said about Sento and Ryuga after they retrieved Katsuragi's data, Gentoku decided to make Ryuga use the dirver by telling him it's the only way they can fare against Hokuto's Hard Smash.
The next day at the Touto capital, Sento agreed to work with Gentoku, following his and Ryuga's encounter with Hokuto's Kamen Rider, but strongly stated that his only intention is to protect Touto, not be a weapon. Gentoku told him he doesn't care what his intentions are and asked Sento how Hokuto managed to build their own Sclash Driver, and he wasn't surprised to learn it was Isurugi and scientist from Namba Heavy Industries. Gentoku then stated they need to figure out their plans until a Touto worker informed him that Hokuto's Kamen Rider, Kazumi Sawatari, has seized a news station and made a live broadcast. Turning on the TV, Gentoku, Sento and Ryuga watched as Kazumi demonstrated Hokuto's only weapon, the Rider System and demanded the Pandora Box and Touto's 20 Fullbottles. He also stated if Touto refuse, Hokuto will take them by force and won't be responsible for anyone whom takes part in the war. Enraged, Gentoku ordered the workers to send a Guardian squad to the TV station, and turned to Sento and Ryuga, telling them to depart as he's counting on them as well before heading to the war room. At night, Gentoku headed for Namba Heavy Industries building, waiting for President Namba to meet with him. As he rose from the couch assuming the person who entered the room was Namba, Gentoku was shocked to see Utsumi standing before him.
After hearing Utsumi recall the tale of his survival, Gentoku sat back down, telling Utsumi he had no choice in shooting him. Showing no sign of remorse, Utsumi told Gentoku he is now the representor of Namba Heavy Industries. Accepting Utsumi's new role, Gentoku demande to know how Faust is still active as it's only organization with the technology to create Smash, surmising it's been relocated in Hokuto. As Utsumi deemed himself incapable of confirming it, Gentoku became enraged as he stated Faust with his and Katsuragi's dream, vowing he won't let anyone else use it for their own pleasures. To Gentoku's confusion, Utsumi told him to leave as two Touto Guardians arrived to escort him out of the building, angering Gentoku.
The next day, Gentoku informed Sento and Ryuga that Utsumi's alive, leaving Sento shocked and Ryuga unfazed as he swung a Touto flag like a baseball bat. Gentoku believed that Utsumi was responsible for building Kazumi's Sclash Driver due to his talent in science. He then told Sento they need to come up with a counter measure against Grease and the Hard Smash, which lead to Sento asking him about the password for the hidden file in Katsuragi's data. Gentoku then remembered Katsuragi once built a device he coined the forbidden item, and as Ryuga asked him if he knew what it was, the capital came under attack by Grease and the Hard Smash. After Build and Cross-Z Charge countered the attack, Sento and the Touto government decided to place most of the Touto Fullbottles in secure locations as they find a way to deal with Hokuto: four at the Prime Minister's building, two at the Touto Institute, another two at the archaeological museum, another two at the garbage plant and the remaining ten stay with Sento. The next day, however, Gentoku received word that Grease has infiltrated the garage plant and took the two bottles hidden in there, he contacted Sento to head there at once. He stepped aside from the table, wondering how the location was leaked.
Later on, Gentoku received word that Grease has broken in the archaeological museum, and sent Sento and Ryuga to intercept them. Ending the call, Gentoku told Masuzawa, a Touto govenment aide, that Hokuto has learned the locations of all the Touto Fullbottles, and pondered how the information was leaked. The following day, Gentoku called Sento and Ryuga to the abandoned Namba Heavy Industries Integrated Sciences Laboratory, informing them of placing the Pandora Box in the abandoned building as leaving the box in the Touto capital is dangerous. Sento agreed while Ryuga demanded to know what else Gentoku wanted to tell them. Obliging both riders, Gentoku told them a Faust branch exists in Hokuto, surmising they will create more Hard Smash like the Three Crows. He then said he wanted them to invade Hokuto and destroy their branch, but Sento declined as he knew what Gentoku proposed would aggrevate the war further and stormed out the building with Ryuga behind him as Gentoku preached that defending Touto won't be enough to end the war unless they invade and hit Hokuto hard. Outside, he heard Sento and Ryuga argue over their role in this war and proceeded towards them, telling Sento he wants to speak to Ryuga alone before leaving with him.
After returning to the Touto capital after learning of Ryuga's reason for participating in the war, Sento asked Gentoku where Ryuga was, but Gentoku showed him a live recording of Grease and the Hard Smash, now the Hazard Smash, entering the abandoned Namba Heavy Industries Integrated Science Laboratory, which was revealed to be a trap set by Gentoku as poisonous gas is emitted, filling up the room. Gentoku took pride in his trap as he stated they would only get in the way of Touto's victory over Hokuto. As Sento asked what he meant, Gentoku revealed he sent Ryuga with their own army of Touto officers and Touto Guardians toward the Skyroad connecting Touto and Hokuto. Sento became upset, but Gentoku assured the only way to stop Hokuto is to destroy their Faust branch or Touto will descend to crisis. Even Masuzawa and the other aides saw Gentoku's motives as invasion and question him why he would go to the extreme without council, but Gentoku, enraged, silenced him and told all in the room he is the leader of Touto until he saw his father, fully recovered, entering the room with Sawa and two Touto officers. As Gentoku asked his father how he recovered so fast, Taizan rushed toward him and demanded Gentoku to call off the invasion. As Gentoku attempted to reason with his father, Taizan silenced him, renounced Gentoku as his son and sentenced him to exile. Shocked and furious, Gentoku obliged to his father's wishes, but transformed into Night Rogue as the Touto officers opened fire at him but the bullets deflected back at them. Taizan, Masuzawa and the remaining aides were shocked to see that Gentoku was the true Night Rogue as he blasted the Pandora Box's container and took it, claiming it as his own as he busted out of the building.
Flying over the city, Rogue was intercepted by Build HawkGatling and shot down. After landing in a decomissioned water fountain and dropping the box, Rogue told Build it's time to settle their rivalry. Turing into RabbitTank Sparkling, Build overpowers Rogue's blows and counters with his own, forcing Rogue to go all out as he claimed he won't be beaten here and formed his wings and performed a drill-spinning kick. To his horror, Build stopped the kick with his hands and tossed him aside before performing a Sparkling Finish kick, defeating Rogue and forcing him out of his transformation as he rolled down the stairs. Wounded, Gentoku complimented the power of the Rider System and told Build it's not over as Build retrieved the Pandora Box. As he rose to his knee, Gentoku promised Build he will return with an even greater power before firing a few shots at Build with his Transteam Gun and left via typhoportation.
Dark Night Fall
- "I won't be finished here!"
- ―Gentoku reclaiming his resolve after his near-death experience and time in anguish.[src]
A few days later, Gentoku was marveling at the newly constructed Sclash Driver in Utsumi's lab, until the scientist walked in. Turning to him, he demanded Utsumi to perform the experiment quickly as possible, and surmised he needs to be administered with enough Nebula gas to increase his Hazard Level, allowing him to transform into a Kamen Rider. To his shock, Utsumi revealed that a candidate for Seito's Kamen Rider has already been chosen by Stalk as the selected candidate walked in the room. Infuriated, Gentoku seized the scientist and demanded to know why he made him kneel, which Utsumi wanted to see if he was being serious. His anger rising, Gentoku attempted to punch Utsumi, but the candidate caught his fist and shoved him aside. As Utsumi backed away, Gentoku attacked the candidate, but saw his hits didn't faze the man, who retaliated with a shot to the gut and a right cross to Gentoku's face. Gentoku did his best to fight, but the candidate's attacks were stronger as he continued to whale on Gentoku, sending him down to the floor bloodied and bruised. As the candidate attempted to continue, Utsumi told him to stop before exiting the room, with the candidate behind him as he grabbed the Sclash Driver, leaving the disoriented Gentoku gazing at their exit before passing out.
Coming to, Gentoku found himself in a prison attire, and being dragged by two Seito Guardians down the cells in the industries lower levels, still dazed and disoriented from his beating. At night, Gentoku was passed out until one of the inmates poured water on his face, waking him. Slowly rising, Gentoku turned to see four inmates, one of which rose from the toilet and noticed who Gentoku was. As the inmate who poured the water on Gentoku asked why he was here, Gentoku turned to the cell door and asked where he was, which the inmate told him he's in the dentention facility in the industries' lower levels for the candidates that have low Hazard Levels. As Gentoku asked them if they underwent the experiment, the lead inmate, already displaying his hatred for Gentoku, told him he's now like the rest of them, a stray dog, but Gentoku told him not to compare him with the rest. As the lead inmate addressed Gentoku's lack of manners, he gestured the two other inmates to grab Gentoku and forced him to his knees. The lead inmate then shoved the screaming Gentoku's head on the floor and squeezed it hard, telling him to scream more, which Gentoku refused as he groaned. By morning, Gentoku refused to give the lead inmate his bread, forcing him and the two inmates to attack Gentoku, which ended with Gentoku coughing up blood. Lying in pain on the floor as the lead inmate took his bread, Gentoku looked at the strange porridge left on his tray and ate it, but found it tasted awful. The inmate, who refused to participate in Gentoku's assault, kneeled by his side and told him the porridge may be bad food, but he needs to eat to survive. The inmate then expressed his envy on Gentoku's wealth before expressing his foolery in believing his only way out was to become Seito's Kamen Rider as Gentoku crawled to the wall and kneeled against it.
Hearing this, Gentoku asked the inmate if he wanted to be a Kamen Rider that badly, which the inmate assured him he did and his lust for a proper life, which Gentoku pondered on while he was unaware that he was being watched by Blood Stalk and Utsumi via security camera. That night, the lead inmate and his two underlings continued their assault on Gentoku as he refused to comply to the lead inmate. Gentoku pleaded for them to stop, but the lead inmate continued to hit him before preparing to perform a cruel act, but only for him to be stopped by the kind inmate's request to stop. As the lead inmate seized the kind one, he told his two underlings to let Gentoku go before he fell to floor. Refusing to comply with the lead inmate's request to attack the kind one, Gentoku remained on the floor shaking as the lead inmate shoved the kind inmate next to Gentoku, telling him to hit him. As he turned to see the kind inmate agreed to the lead inmae's demand, Gentoku stated they both lost the lottery as he rose up and complied to the lead inmate's demand, punching the kind one multiple times before he fell down. Pumped by adrenaline, Gentoku continued to punch the kind inmate, even when the lead inmate told him to stop. Turning his attention to his oppressor, Gentoku attacked him, which lead to the lead inmate and his underlings to begin their attack on Gentoku once more until he lost consciousness, all of which was being watched by Utsumi from the camera.
Gentoku was lost deep in his subconsciousness, which to everyone believed he was dead and tossed to the morgue, which was ran by Norio Matsui and Yoshikazu Takahashi, the two assistants Takumi Katsuragi was assigned to in the begging of Faust three years earlier. Gentoku came to as both Takahashi and Matsui unzipped his body back and pulled him out, telling him he's in the morgue as they found his body and asked for assistance after they found he was still alive. Realizing both Matsui and Takahashi saved him, Gentoku did something he hasn't done in a decade: express gratitude by hugging them and stating he's in their debt. Gentoku then asked them why they're here, to which the duo revealed them moved to Namba Heavy Industries after the Touto division of Faust fell apart, and they expressed their willingness to return to Faust at anytime as they reminded Gentoku of their pledge from the creation of Faust. Regaining his conviction and will, a bandaged Gentoku rose up, with Matsui and Takahashi assisting him as he stumbled, and demande to know where the Kamen Rider candidate was, which they revealed he was in the iindustries' research lab. Heading out the door, Gentoku told them he won't allow himself to perish here before existing.
Reaching the lab, Gentoku knocked out a lab assistant and attacked the candidate with enough ferocity that left the candidate cut up in a pool of his own blood and moaning in pain as Gentoku sat on a computer with the candidate's blood all over him, and the Sclash Driver by his side. He looked up to see Stalk and a shocked Utsumi staring at his transgression, then asked him what he plans to do with the candidate no longer qualified to become Seito's Kamen Rider. Stalk, however, expressed his excitement and addressed to Gentoku that he has passed, meaning he will now become the Kamen Rider. After dragging the former candidate for medical treatment and mopping away his spilled blood, Gentoku stood by the vat as the lab assistants prepared for the procedure, then proceeded to climb in the vat, placing the face mask on as he laid down, and awaited to breathe in the Nebula gas. As the gas was administered in his body, Gentoku writhed in pain, forcing Stalk to hold him down while Gentoku muffle-screamed in pain.
ROGUE: The Final Chapter
With the experiments leveling him up to Hazard Level 3.5, Gentoku was pitted against several other candidates in a locked and closed cage match where he was asked to kill by both Utsumi and Stalk. Gentoku then told Utsumi that he was sorry for what he had done to him before and went off to fight the other candidates.
Kamen Rider Rogue
Once Kamen Rider Build and Grease's proxy battle to settle the war between Touto and Hokuto ended with Build's victory, Gentoku, as Kamen Rider Rogue, led a group of Seito Guardians to apprehend Hokuto's prime minister, Yoshiko Tajimi. He was the last to show up as the Seito Guardians surrounded and apprehended Taijimi, dragging the upper body of a Hokuto Guardian by its head. After dropping the body, Blood Stalk introduces him to Taijimi as Seito's Kamen Rider.
After viewing a conversation between Blood Stalk and Kazumi Sawatari over the phone, Gentoku, in human form, proceeded to Touto through Hokuto, leaving damage in his wake as he proceeded to a tunnel, and transformed into Kamen Rider Rogue as he exited the tunnel. He arrived in time to see Build RabbitTank Sparkling and Cross-Z Charge gaining the upper hand on the Washio Brothers. As all combatants, Kazumi and Akaba spotted Rogue, Fu introduced Rogue as Seito's Kamen Rider before he and Rai vanished. Rogue, being silent, gestured Build and Cross-Z Charge to come at him, with Cross-Z Charge making the first move, followed by Build. However, their punches made no dent, but Rogue's punches drove them back. As Cross-Z Charge attempted to attack Rogue again, Rogue punched him the gut, forcing him on his kness as he placed his Crocodile Crack Fullbottle in his own Nebulasteam Gun, firing a Funky Break at Cross-Z Charge, sending him flying into a hillside before cancelling his transformation. Seeing Ryuga injured, Build mustered enough strength to drive Rogue back, but his punch did no damage as he dragged him along the ground. As they stopped, Rogue performed a Crocodile Finish Rider Kick, forcing Build back along the ground with enough energy before he was caught in a large explosion, cancelling Sento's transformation before he fell down to the dirt. Struggling, Sento demanded Rogue his name, to which Rogue stated his title and Ryuga noticed his voice sounded familiar. Pulling the Crocodile Crack bottle out of his Sclash Driver, Gentoku revealed himself, stating they've met again but addressed Sento as Katsuragi as Sento looked at him with shock.
Seizing the Pandora Box
- "Vengeance...vengeance...I abandoned thoughts of that long ago. I became a Rider to defeat Touto. This time, I'll reunite the country with my own hands. That is all I want."
- ―Rogue's new resolve as he overpowers Build.[src]
Later on, Gentoku, the Washio brothers and a squad of Seito Guardians marched onto the Touto Prime Minister's residence, viciously attacking the Touto officers in their wake, while Gentoku proceeded inside. Heading into the war briefing room, Gentoku raised his Nebulasteam Gun at his father and four coworkers. Surprised to see what has become of his son, Taizan ordered the four workers to leave now, leaving him alone with Gentoku. As Taizan pressed the code to release the Pandora Box, he attempted to remind Gentoku of the kind of person he was before being bathed by the Pandora Box's light: a kind man, and expressed his remorse for having his son go to the ceremony. However, Gentoku raised his gun at his father, stating he's not interested in old stories as Taizan finished putting in the code and the Pandora Box emerged from the floor. He then lowered his weapon and headed for the box until Sento, in Build RabbitTank form, appeared. Build stated he won't let Gentoku take the box as he transformed into Kamen Rider Rogue. Rogue told Build the residence is no place for their fight as he placed the Phoenix Fullbottle in the Nebulasteam Gun and coated himself in a phoenix-shaped fire as he grabbed the box and burst out of the building, picking up the Washio brothers, in their Bro's forms, and headed for the Skywall with Build, in HawkGatling form, Grease, Castle Hazard Smash, and Cross-Z Charge in pursuit.
Rogue and the Bro's Kaisers stopped at Faust's first lair, waiting for the Kamen Riders and Castle Hazard Smash to catch up to them. Rogue then unveiled the Skywall will be the perfect spot for their fight, as it's the instrument that made each of them what they are now. As he dropped the Pandora Box and placed his foot on it, he claimed he will gather all the Fullbottles and open the box to end everything and begin anew. He advances toward Build, who changes into RabbitTank Sparkling, and engaged him as Cross-Z Charge engaged Remocon Bro's and Grease, with Castle Hazard Smash, take on Engine Bro's. During the fight, Build proclaimed his resolve to fight for love and peace and pointed out that Rogue became a Kamen Rider for vengeance, deeming them different from one another. Rogue gains the upper hand due to his new power, and told Build he abandoned thoughts like vengeance as he knocked Build to the ground. Rogue then said his reason for becoming a rider was to destroy Touto and reunite all of Japan with his own hands. As Rogue continued to overpower Build, he pulled out the Hazard Trigger and transformed into Build RabbitTank Hazard, and was able to deal more effective blows as he addressed to Rogue the difference between reuniting a country and taking it over by force. Rogue, however, brushed off the punches and overpowers Build once more, telling him his dreams are rubbish as neither him nor any of Build's comrades can comprehend the burden of governing a country. Deeming his determination as adamant, Rogue performs a Crack Up Finisher and sent Build into the Skywall, causing an explosion and cancelling Sento's transformation, leaving Cross-Z Charge and Grease shocked at Rogue's power exceeding the Hazard Trigger's before they were bested by the Bro's Kaisers as well. As Rogue prepares to deliver the killing blow, he spotted Misora approaching with her eyes closed and stopped close to Rouge and Sento. All the riders gazed at Misora as she opened her eyes, which are glowing green.
After she opened her eyes, Misora raised her arm with her bangle and generated a vortex of energy, ensnaring Rogue and the Washio brothers. Lifting them in the air, Misora's bracelet reacted to the Skywall, causing a section of it to collapse, exposing an opening and allowing her to toss Rouge and the Washio Brothers out of Touto and back into Seito without the Pandora Box. The nxet day in Seito, Gentoku stood beside Utsumi and Namba as they watched the Washio brothers train, hearing Namba's claim to become the ultimate defense contractor by utilizing both the Pandora Box's power and the weapons developed by Namba Heavy Industries. After Utsumi received a call from their spy about the Pandora Box being moved to a new location, Namba told the Washio brothers to retrieve it while Utsumi gave a new mission to Gentoku.
After the Washio brothers were deceived and Seito's spy had been compromised, Gentoku made his way to the box's true location: an abandoned warehouse guarded by Akaba. After declining to hand over the box, Akaba turned into Castle Hazard Smash, forcing Gentoku to transform into Rogue and overpower the Hazard Smash. Despite Rogue's power, he was kept at bay from the box, forcing him to rip off Akaba's right Ground Rampart and land vital blows, sending the Smash backwards. Rogue was surprised Akaba was able to hold on beyond his limit, and decided to end it with a Crack Up Rider punch as Akaba lunged forward, sending him flying once more with more force as Sento, Kazumi and Ryuga entered the warehouse and witnessed the devastating blow. Rogue watched as Akaba disintegrated and Kazumi mourning the loss of his friend before approaching Rogue with Sento and Ryuga by his side. All three riders transformed into Build RabbitTank Sparkling, Grease and Cross-Z Charge and rushed Rogue, whom managed to overpower all three riders and kicked Grease to Build and Cross-Z Charge. He formed his Nebulasteam Rifle and inserted the Crocodile Crack bottle in it, blasting a Crocodile Funky Shot at them, and the blast's shockwave freed the Pandora Box from its container.
Before he could apprehend the box, Misora appeared and attempted to summon her power against Rogue. Claiming the same trick won't work again, Rogue separated his Nebulasteam Gun from his Steam Blade and fired at Misora, but Cross-Z Charge shielded her. Having enough, Build turned into RabbitTank Hazard and rushed toward Rogue, both riders trading blows until Build succumbed to the Hazard Trigger, losing consciousness and activated the trigger's Overflow. Rushing toward Rogue with superspeed, the out-of-control Build performed a Hazard Finish kick, knocking Rogue back with enough force, right near the Pandora Box. Rogue admit he's been damaged, but Build won't win in his berserk state as he dodged Build and pulled Grease in front of him, allowing the berserk rider to attack him while Rogue took the chance to grab the box. Cross-Z Charge, however, reentered the fight and performed a Scrap Break kick, but Rogue overpowered him with a Crack Up Finish kick and forced him out of his transformation. With no one left to challenge him, Rogue took the Pandora Box and left the warehouse with the Phoenix bottle in his Nebulasteam Gun, bursting through the front on his way out.
Touto-Seito Proxy Fight
Proposed by Midou, Gentoku, along with the Washio brothers, became involved in a proxy fight between Touto and Seito for the Pandora Box and the Fullbottles. He sat by himself in the locker room of the proxy fight's location, waiting for his turn to fight Sento.After Hell Bro's defeated Cross-Z Charge, Utsumi approached Gentoku with his Sclash Driver, uploading data on Sento's new power-up into the driver, giving Gentoku a countermeasure against it. After the upload was finished, Utsumi told Gentoku that the final match's outcome will be based on his skills as he handed the driver back to him. Ustumi reminded him of his vengeance, but Gentoku stated he doesn't care about vengeance, and only fights any opponent before him for the greater cause as he took his driver and proceeded to the arena.
With both riders awaiting for the announcer to start the fight, Sento and Gentoku decided it's time to settle their score with one another. Sento told Gentoku he won't allow Seito to win the proxy fight and gain control of all of Japan as he placed his Build Driver on. As Gentoku placed his Sclash Driver on, he called Sento by his true name as he told Sento back when he was Katsuragi that he wanted weapons clashing with one another for the top spot. Sento told Gentoku once more the Rider System isn't a weapon for war before transforming into Build RabbitTank Sparkling, then Gentoku transfored into Kamen Rider Rogue before the announcer gave the word to fight. Raising his Nebulasteam Gun, Rogue made the first move by firing at Build, whom blocked his shots with his Drill Crusher and 4Koma Ninpoutou while running at him. Grabbing both of Build's arms as they fought, Rogue asked him if he was sure the Rider System wasn't a weapon, distracting Build momentarily to get a shot at him with his gun, but Build dodged it. With Build's attacks not connecting, Rogue seized his Ninpoutou and told him as Katsuragi, he did believe the system was a weapon before tossing Build's arm up, providing an opening for his Nebulasteam Gun. As he fired, Rogue remembered a conversation he had with Katsuragi, years during Faust's creation, where he told Katsuragi they've reached the point of no return with the Rider System. Katsuragi told Gentoku that it's because of science humanity has evolved constantly, and that he would sell his soul to the devil and allow his system to partake in bloodthirsty wars if it means science will show the path to the future.
Shifting his focus back to the fight, Rogue summoned his Steam Blade and forced Build back, telling him human history underwent countless conflicts to create the present humanity resides in. Countering Build's weapons with his own, Rogue told Build that he, as Katsuragi, knew science would contribute to war as he shot Build to the ground, and added that knowing this he still went forward with the Rider System. Rising back up, Build told Rogue there were no scientists whom wanted war as he lunged forward, stating that scientists like him use science for peace and give people happiness as he threw a series of punches at Rogue before Rogue kicked him. Rogue then pointed that Build's usage of the Hazard Trigger makes him a hypocrite, pointing the folly in turning into a rampaging weapon of destruction to bring peace, but Build told him he shouldn't have built it as he labelled it as a forbidden item. Cutting Build off, Rogue told him as he still built it, he should have known how many people would've been hurt as a result before firing a Funky Shot from his Nebulasteam Rifle, sending Build flying into the energy nets. As Build fell to the floor, Rogue told him he should've known everything that has happened to their current place in time happened exactly the it would end up. Build told Rogue as he rose, war brings only sorrow and if Katsuragi was in fact the person who started it, it was his job to end it as he placed the Rose bottle in his Drill Crusher gun mode and fired a Vortex Break alongside his Hawk Gatlinger, but Rogue jumped over him and countered with a Crack Up Finish Rider punch, forcing Build to drop the Rose, Turtle, Gorilla and Light Fullbottles as he flew to the other side of the arena. Grabbing the dropped bottles, Rogue told Build his Sparkling form and whatever form he has is no match for him. Slowly rising up, Build stated that it's because of his friends he's the person who utilized the Rider System for justice, pulling out the Hazard Trigger and setting it in his driver as he vows to surpass Katsuragi in his own way.
Rogue scoffed at Build's words, seeing it pointless as Build still employed Katsuragi's inventions until he saw Build pull out a new device, creating a new transformation with the Hazard Trigger: Build RabbitRabbit Form. Before his eyes, Rogue realized Build's attacks were connecting, allowing Build to overpower him with greater speed. Rogue compared Build's new power with the Hazard Trigger's berserk effect, yet Build is still conscious. Build stated he won't ever lose control of himself again, that his current power is his own as continue his quick assaults on Rogue, sending him rolling across the floor. Backed in a corner, Rogue wonder how strong Build can get as Build stated his power is the power of justice and his own before summoning his newest weapon: the Fullbottle Buster. After converting it into Buster Cannon Mode, Build placed the Rabbit bottle in it and executed a Fullbottle Break, damaging Rogue's right hand. Build then added the Panda bottle and performed a Just Match Break, causing more damage to Rogue. Build then added the Taka bottle, executing a Miracle Match Break, overpowering Rogue's Funky Shot, sending him flying to a corner in the arena. Placing away his new weapon, Build executed a RabbitRabbit Finish Rider kick, sending Rogue straight through the wall and outside the building and colliding into a concrete wall, covering him in rubble. With the match continuing until either Rogue or Build is knocked out of their transformation or in incapacitated, Rogue burst through the rubble as the contingency system in his Sclash Driver kicked in, waiting to overpower the approaching Build once more.
As Build approached the wreckage, Rogue emerged from the smoke and pulled out the Diamond bottle, which made Build realized that Seito had the Fullbottles that Hokuto stole from Touto. Stating the counterattack will begin, Rogue inserted the Diamond bottle in his Sclash Driver and executed a Discharge Crush Rider punch, launching energy diamonds at Build, whom dodged and countered with his stretching ability, but to his surprise, Rogue countered his attacks with Diamond shields. Build then summoned his Fullbottle Buster and shot at Rogue, but he created small diamonds to reflect the blast back at Build, forcing him down. As Build rose and used his speed to try and attack Rogue, Rogue created diamond shields to deflect Build's attacks before punching him to a fence. Struggling to rise, Build realized Rogue was reading his moves as he continued his fight with Rogue.
Rogue continued to overpower Build's attacks with his own, slashing at Build viciously with his Steam Blade. As he pressed his attacks with more ferocity, Rogue told Build he will defeat him and obtain greater power to restrengthen Japan. Recollecting on a memory of argument between himself and his father Taizan over military force, Rogue realized that trusting his ambitions alone won't change anything and referred to himself as trash that can't do anything. To change in order to see his ambitions come to fruition, Rogue took his pride and vanity and cast them away to be reborn as Kamen Rider Rogue, executing a Crack Up Finish Rider kick, dealing great damage to Build as he told him his ifghting for love and peace are nothing more than illusions and they can't help create a country before continuing his assaults.
As the sun rose, Rogue delivered a blow hard enough to make Build fall to the floor. Prepared to finish off Build, Rogue lunged forward, but to his surprise, Build rose back up quickly and punched him back after he saw Sawa giving him a sign, unaware that Sawa had Kazumi rescued Nabeshima and his family as Namba had them hostage in exchange for the data on Build's RabbitRabbit form. Rogue became confused as Build removed the FullFull bottle and shook it, hearing it say Tank and saw Build reinsert it in his driver, transforming into another new form: Build TankTank. Rogue attempted to punch Build, but he stopped it with the treads on one of his Fight Might Gauntlet, sending him flying with shots from his BLD TankTank Shoulders and punching him aside with greater strength. Rising, Rogue attempted to use the contingency for a counterattack, but the system malfunctioned as it doesn't account data for the TankTank form, and attempted to rush Build, whom brushed Rogue aside, then counter Rogue's attacks with stronger ones. Being driver into a corner from Build's tremendous assaults, Rogue asked how he got stronger, but Build asked what's wrong with promoting ideals as he attacked Rogue with his Fullbottle Buster in Buster Blade mode.
Continuing his attacks on Rogue, Build stated he knew fighting for love and peace isn't realistic, and that he fights not to bring it by himself, but to reveal it in everyone's heart before converting his weapon in Buster Cannon mode and inserted the Tank, Jet, Gatling and Rocket bottles for a Ultimate Match Break shot, destroying Rogue's diamond shield and dealing him even greater damage. Build then placed the FullFull RabbitTank bottle in the Fullbuttle Buster, performing a FullFull Match Break as Rogue attempted to counter with diamond energy punches, but failed and the attack connected, sending Rogue flying to the stairs and cancelling his transformation as he rolled down, a similar predicament to his losing to Build RabbitTank Sparkling before he was exiled from Touto. Gentoku knew that he lost, meaning Touto wins the proxy match 2-1, and he turned to see his father arriving with two Touto security personal. After Taizan congratulated Sento for his efforts, Gentoku was shocked to hear his father tell him to return to Touto, but he rejected his father's offer and left.
Road of Redemption & Pain of Loss
- "Shut up and listen to me. The Prime Minister of Seito is no longer Mido. Namba just stole his face. I planned on using the Pandora Box as a deterrent force in order to reunite the country. But Namba has other plans. He wants to use that power to rule the world. Take it before they open it!"
- ―Rogue revealing to Build the reason behind Seito's invasion into Touto.[src]
The next day, Gentoku spied on Utsumi and Mido at a golf range, whom Gentoku learned was Namba in disguise due to Stalk's face alteration ability, and learned of Namba's true motives to conquer the world with the Pandora Box. new weapon, engaged him first, planning to avenge Kasumi. Intrigued by Cross-Z's increased strength, Rogue told him why Stalk wanted him from the beginning as he drew out his Nebula Steam Gun and fired. As Cross-Z dodged his blasts, Rogue admit to him that Stalk chose to inject Kasumi with the Nebula gas so she could die and in exchange, raise Cross-Z's Hazard Level through his emotions. Not wanting to waste any more time, Rogue told Cross-Z his growth as a Kamen Rider was one of Stalk's goal from the get-go, infuriating Cross-Z enough to get him to rush at Rogue in anger, allowing Rogue to perform a Crack Up Rider punch, striking a heavy blow to Cross-Z before his Draconic Rider punch could connect.Realizing this new danger, Gentoku decided to take action as he left for the Pandora Tower and arrived in time to see Kamen Riders Build TankTank, Cross-Z Dragon, and Grease fight Hell Bro's and two Hard Guardians. After transforming into Kamen Rider Rogue, he attempted to engage Build until Cross-Z, wielding a
After Ryuga fell to his knees from this revelation after his transformation cancelled, Build defeated Hell Bro's and transformed into RabbitRabbit before engaging Rogue. As Build inserted his FullFull RabbitTank Bottle into the Fullbottle Buster blade mode, Rogue saw his opening and instead of punching, he pulled Build closer to him, telling him to listen as he revealed that Namba has taken Mido's identity before he noticed Fu Wahsio struggling to rise. Rogue kept up the ruse that they were fighting as he dragged Build to the sand, and told Build that Rogue's original plan for the Pandora Box was as a deterrent to reunite Japan, but Namba wants to use the martian relic to rule the Earth. After telling Build to take the box from them before it could be opened, Build asked him why he's telling him, and as Rogue rolled over with Build's weapon over his chest, he revealed to Rogue that he has a chip in his body that's capable of killing him in the event he betrays Namba and Stalk. After revealing this revelation to Build, Rogue told him to finish him off as he pushed him off and rose, attempting to perform a Crack Up Rider punch, allowing Build to finish him with a FullFull Match Break, cancelling Rogue's transformation as he fell on his back. As Sento, Ryuga and Kazumi left to confront Stalk, Gentoku clenched a fist full of sand in anger before slamming his palm down on the ground.
After Sento, Kazumi, and Ryuga retrieved the Pandora Box from the tower, Gentoku traveled to Hokuto to see Utsumi, with two Hard Guardians, having taken Kazumi's friends and family hostage in an attempted exchange for the Pandora Box and all sixty Fullbottles. Waiting until night, Gentoku stood behind Utsumi as he surmised that Kazumi isn't coming, and then one of the hostages stated the obvious that Kazumi refused to oblige the ransom because he's risking his own life to protect the rest, and two more stated that they'd risk dying than let Kazumi accept Utsumi's terms. Obliging their wish, Utsumi ordered Gentoku to kill them, but as he transformed into Kamen Rider Rogue, he cut them free with his Steam Blade, telling Utsumi there's no point in killing them as he approached his former assistant. Even as Utsumi threatened him with the kill chip in his body, Rogue knocked the switch from Utsumi's hand and engaged the Hard Guardians, allowing the farmers to escape. After Rogue destroyed the Guardians, he turned his sight on Utsumi, who managed to retrieve the switch and activated the chip, shocking Rogue and cancelling his transformation. Falling to the ground in pain, Gentoku received a kick in the face from a furious Utsumi, causing him to roll on his stomach as he looked at Utsumi with anger and pain.
To make up for his defiance, Gentoku, as Rogue, attacked the Touto capital with Blood Stalk to take Taizan Himuro hostage, while Engine Bro's and Remocon Bro's attacked at a different location as a distraction for Kamen Riders Build and Grease. As Rogue and Stalk easily defeated the Touto Guardians, Kamen Rider Cross-Z, who didn't assist his fellow riders due to learning his alien origins, arrived and engaged Stalk, who told Rogue to proceed ahead while he deals with Cross-Z. Destroying the Touto Guardians as he made his way in the main office, Rogue turned to his father, who told him the box has been moved to a new location, but Rogue assured the prime minister he's here for him. As Sento and Ryuga, who just defeated Stalk with his new Cross-Z Magma form, entered the office, Rogue seized Taizan and typhoported himself and his father out of Touto.
Placing Taizan in a cell at an abandoned factory, Gentoku and Utsumi stood outside as the prime minister asked his son what he's done, which Gentoku, keeping up his act, told him Seito's closer to reunifying Japan, which will bring him closer to his own goal. Seeing the disappoint in his father's face as he told them they can't reunite the country until they've seen the faces of the people suffering in this war, Gentoku stood still while Utsumi banged his fist on the cell door and told Taizan to be silent. As Utsumi walked away from the cell, Gentoku kept his eyes on his father until Utsumi called him. Approaching Utsumi's side, Gentoku turned his head as Utsumi told him to kill his father once Sento retrieved the device Stalk wants in return for Taizan, and pointed out that it's a good thing for Gentoku to punish the one responsible for his exile. As Utsumi left, Gentoku turned back to his father, now seeing things have gone too far.
That night, Gentoku decided he can't keep up his villain role any longer and approached his father's cell, his Nebulasteam Gun raised at him until he shot the lock, freeing the door. As Taizan looked confused, Gentoku told him they're leaving and revealed to his father that he wanted to reunite Japan to create a new society with happy denizens and no borders, which is what Gentoku attempted to do with Faust, but the Pandora Box's light warped him and turned him into the fiendish person he once was. Gentoku told his father as he got out of the cell to leave right now, which Taizan accepted. Heading outside, Gentoku took the lead to make sure it's safe until Utsumi and a Strong Clone Smash appeared them. As Utsumi boasted his suspicion of this event, Gentoku told him he's the foolish one for being on the wrong side and for not breaking free of Namba's grasp, which angered Utsumi as he pulled out the switch and triggered Gentoku's chip. As he fell to the ground, Gentoku moaned in pain before screaming from Utsumi grinding his back with his shoe, forcing Taizan to shove the scientist, which caused him to drop the switch. Seeing the switch on the floor, Gentoku grabbed it and tossed it far from Utsumi's reach before transforming into Kamen Rider Rogue.
Approaching Utsumi, who instructed the Clone Smash to attack him, Rogue dodged the creature's attacks and countered with his own before destroy it with a Crack Up Rider punch. Turning back to Utsumi, Rogue began to walk towards him again until he felt the chip activate and shocked him, cancelling his transformation as he fell to the ground. Gentoku turned to see Blood Stalk, sitting on a nearby vat, with a second remote in his hand. Gentoku remained silent as Stalk told Taizan that the Pandora Box's light in Gentoku is now gone due to his increased Hazard Level to become a Kamen Rider. Jumping down, Stalk also pointed out to Taizan that Gentoku put up this facade to keep his father in power to reunite Japan after he realized he can't do it himself, which touched Taizan until Utsumi seized him at gunpoint. Seeing his father in the enemy's thrall once more, Gentoku turned his head to the ground as Stalk told him his fate is in his hands as he kicked Gentoku in the face before leaving with Utsumi and Taizan. Spotting the first switch, Gentoku grabbed it and positioned himself up, pulling out his cellphone and called Sento Kiryu. As Sento answered his call, Gentoku told him to find a way to deactivate it before begging for Sento's help to save his father.
After Sento agreed and altered the chip's signal to deactivate it, Gentoku, as Rogue, sneaked in the wharf, where Stalk told Sento and Ryuga to meet him to exchange the Evol-Driver for Taizan, and remained in the dark. Seeing Stalk demanding the driver now, Rogue jumped to his father and kicking a Faust Guardian away before forcing Stalk back with his Nebulasteam Gun raised at him. Stalk admitted his disappointment for Rogue's betrayal after letting him live before activating the switch, which Rogue felt nothing due to the chip being deactivated. Sento revealed that he and Rogue formed an alliance to save Taizan and that he changed the chip's signal to deactivate it, which Stalk anticipated as he tossed the remote aside. Rogue watched his father trying to leave with the driver, but another Hard Guardian and Faust Guardians blocked his path until Kamen Rider Grease arrived, knocking the robots away from Taizan.
After Sento and Ryuga transformed into Kamen Riders Build RabbitRabbit and Cross-Z Magma, Stalk ordered the Guardians to not let any of them to escape as all Kamen Riders engaged the robots, but Cross-Z Magma engaged Stalk. While the fight went on, Rogue protected his father from the Faust Guardians, easily overpowering them. Spotting Stalk lying on the ground, Rogue told his father to leave, but Stalk spotted him and became infuriated. Rogue saw Stalk fly up in a cobra energy projection after projecting an explosive energy wave to force Cross-Z away, forcing him to follow by the Phoenix Fullbottle Charge Crush.
Following through the openings left by Stalk, Rogue spotted Stalk approaching Misora, who had the Evol-Driver in her hands, and attacked him, forcing him away from her. Landing on his knee after Stalk rolled over, Rogue told him he's his opponent, which Stalk berated him for being stubborn before both engaged in combat. As Misora, Sawa, and Taizan watched the fight, Rogue overpowers Stalk and defeats him with a Crack Up Rider kick, cancelling Stalk's transformation. Rogue watched as Misora walked toward Isurugi's body until Utsumi seized her and confiscated the driver from her. After Utsumi shoved her aside, Rogue watched in horror as Utsumi tossed the device to Isurugi, who placed it on with joy, inserting a crimson cobra bottle and a black bottle, and transformed into a Kamen Rider: Kamen Rider Evol Cobra, which he dubbed Evol Phase 1. As Misora, Taizan, Sawa and Utusmi marveled at the new rider, Evol began walking toward Rogue, forcing him to engage him with a punch, but Evol caught it and told Rogue he's the warm-up. Rogue was shocked as Evol tossed his fist aside with such strength and dodged Rogue's attack with greater speed untl Evol countered with devastating assaults, doing critical damage to Rogue before unleashing an Evoltic Cobra Rider kick, sending Rogue bouncing off a beam and landing hard on the ground, cancelling his transformation.
- "Gentoku...Atone for your crimes...and rebuild...the country. You can do it."
"I'm counting on you...my foolish son."
- ―Taizan's final words to Gentoku.[src]
In immense pain, Gentoku watched as Evol approached him, generating spatial energy in his hand and telling him he has outlived his usefulness before firing the energy blast. As Gentoku watched the energy blast approached him, he spotted his father taking the attack from behind before falling to the ground. Being petrified for a few moments, Gentoku snapped out of it and grabbed his dying father frantically, who told Gentoku to atone for his crimes and assures him he can reunite Japan before taking his final breath and passed. With his father's body lying in his arms, Gentoku called out to him before screaming in agony.As Sento, Ryuga, and Kazumi arrived out to see what has occured, Gentoku remained motionless as he held his father's body. During the fight between Kamen Riders, Build, Cross-Z, Grease, and Evol, who emerged the victor, Gentoku took his father's handkerchief and left, leaving the body for the authorities to claim. Two days later as Seito's forces dominates Touto, Gentoku, sitting in rubble with his father's handkerchief in hand, shifted his gaze to a broadcast detailing the death of his father, and his successor Mayuzumi is attempting to open negotiations of peace while the citizens panic.
Joining the Kamen Riders
- "I can't bring the country together. But I can lay the foundation for it. For love and peace..."
- ―Rogue's new resolve as he joins the Kamen Riders in the fight against Evolto.[src]
As Evolto told them he'll be taking the Phoenix bottle before inserting the Cobra and Rider Evolbottles in the belt and transformed into Kamen Rider Evol Cobra, Gentoku, Sento, and Kazumi placed their respective Build and Sclash Drives on, transforming into Kamen Riders Rogue, Build RabbitRabbit, and Grease. As all three riders rushed Evol, Rogue, Build, and Grease executed combo attacks, but found that Evol was holding his own. After deflecting Grease's Scrap Finish Rider kick with an energy burst, Rogue gave Build the Phoenix bottle as he told him he'll act as a decoy to allow Build to take the remaining Fullbotttles. Summoning his Nebulasteam Gun, Rogue told Build he's counting on him before firing at Evol, who dodged the shots and disarmed Rogue. Unwavering, Rogue executed a Crack-Up Finish Rider kick as he vowed to avenge his father, kicking Evol with the attack, which forced him to drop the panel. Rogue watched as Build ran to the panel, and Grease grabbed Evol as the alien fired at Build, and then Evol shot Grease in the face before firing a combustive energy at the Hokuto rider, sending him flying out of the tower.
Spotting Evol heading to the panel, Rogue intercepted it and tossed it to Build before knocking the gun from Evol's hand and executed a series of punches, but Evol brushed them off and seized Rogue and scolded him for his involvement in this war and the crimes he's committed before executing an Evoltic Finish Rider punch, sending Rogue flying out of the tower. Forced out of his transformation, Gentoku approached an injured Kazumi, who stated he's counting on the genius physicist. However, Build's efforts failed as Evol placed the last three panels on the Pandora Box, completing the tower as a black cyclone generated around it with rubble and purple lighting coursing around it.
After the Maritan Queen Vernage teleported both Sento and the depleted Pandora Box back to nascita, Gentoku and Kazumi met up with Sento in the underground lab to learn that the true power of the box was Evolto's true power. Gentoku stood by Sento's right as Vernage explained the Pandora Tower will open a portal to destroy the Earth, just as it did to Mars, and explained Evolto's origins and how she defeated him. After hearing the queen's words, Gentoku surmised that the energy in the box was Evolto's all along, which she confirmed and stated Evolto must not regain his complete form. As Sento stated they can't do anything with the Fullbottles emptied, Gentoku saw Vernage raised her arm and refilled all sixty bottles with their elements. Vernage explained that when she first possessed Misora 10 years ago, she tried to deplete all of the bottles with her powers, but didn't finished in time as both her and Msiora slipped into a coma. Vernage pleaded with Sento, Kazumi, and Gentoku to stop Evolto before she lost consciousness fell. Gentoku saw Sento try to grab her, but was pushed by Kazumi, who caught Misora. Gentoku looked at Sento as Kazumi was talking aloud about his feelings for holding his idol until Sento snapped Kazumi out of his trance. As both Sento and Kazumi carried Misora to bed, Sawa walked in and saw Gentoku, which shocked her. Gentoku began to walk towards the stairs as Kazumi asked him where he's going, which Gentoku replied his role's finished as they lost the Phoenix bottle to Evolto. Gentoku closed the refrigerator door behind him until he sensed something coming from the door and investigated, but only to be surprised to see Kazumi's head pop out of the freezer section, who then told Gentoku to follow him.
Heading to the Hokuto-Touto Sky road where the graves of Akaba, Aoba, and Kiba rests, Kazumi told Gentoku he hasn't forgiven him for killing Masaru, forcing Gentoku to remember slaying the Castle Hazard Smash as Evolto's words echo in his mind. Turning to Kazumi, Gentoku asked him if killing him will make the Hokuto rider feel better, but Kazumi told Gentoku it won't be good for him as he placed the Robot Sclashjelly in his Sclash Driver and offered a proposal: if he wins, Gentoku has to do what he asks. After transforming into Kamen Rider Grease, Gentoku dodged Grease's attacks as he placed his own Sclash Driver on and inserted his Crocodile Crack bottle, transforming into Kamen Rider Rogue. Engaging Grease, Rogue found himself outmatched as he blocked Grease's assaults and saw his own attacks are not fazing Grease like before. As Grease stated his experience helped him raise his strength, Rogue became overwhelmed from Grease's assaults until both riders kicked each other aside, allowing Rogue to execute a Crack Up Rider kick, but Grease deflected it and asked if Rogue can raise his own Hazard Level after Grease stated he can raise his own level by thinking of his home in Hokuto. Remembering his father's sacrifice, Rogue saw Grease executing a Scrap Rider kick, sending Rogue flying backwards and cancelling his transformation. Gentoku writhed in pain as Kazumi cancelled his transformation and walked by him, reminding him of the proposal, which Gentoku obliged and asked Kazumi what he wants. Kazumi told Gentoku to join himself and Sento as he stood aside to reveal the graves of Kiba, Akaba, and Aoba, and quote that the Three Crows would scold Kazumi for getting irritated over Akaba's death. Gentoku became shocked as Kazumi told him to take time before making a decision, leaving Gentoku alone to stare at the Three Crows' graves.
Later on, Gentoku received a call from Kazumi and Ryuga, who was freed from Evolto after the alien possessed Sento's body, to meet at the vacated Faust backup lair, which made Gentoku reflect on his deceased father's words to atone until Kazumi and Ryuga arrived late. Ryuga and Kazumi got side-tracked and went-off topic as both stated the other got lost, until Gentoku asked them what they want, which Ryuga revealed he lost the ability to transform into a Kamen Rider due to Evolto absorbing his essence from Ryuga's body and asked to undergo the Nebula gas procedure again. Gentoku revealed he can't because he lacked the knowledge to perform the procedure, and when Ryuga reminded him of his former position as head of the Touto Institute, Gentoku also revealed he was placed there at his father's request, which left Ryuga and Kazumi shocked. Gentoku them told Ryuga the other way to become a Kamen Rider without the Nebula gas procedure is through gene manipulation, which Evolto possesses, leaving Ryuga to ask Gentoku to assist Kazumi and begged him to fight with them. Shocked, Gentoku reminded Ryuga he's the reason Ryuga's fiance is dead, and Ryuga said he knows and that's why he doesn't want to lose anyone close to him again. Gentoku declines as he said he lacks the determination to utilize his Sclash Driver's full potential now that his father's gone. As Ryuga received a call from Evolto, he informed Gentoku and Kazumi that Evolto wants them to hand over the Pandora Box and Fullbottles if they want to see Sento again, which Kazumi stated he'll do it, and reminded the protesting Ryuga of how Sento fought to protect others even when the odds were against him. As Kazumi and Ryuga left, Gentoku pondered on Kazumi's parting words of how Gentoku's father isn't the only person who can reunite Japan, allowing him to gain a new resolve to fight.
Arriving at the meeting place to see Engine Bro's and Remocon Bro's overpower Kamen Rider Grease, Gentoku transformed into Kamen Rider Rogue and deflected the Washio brothers' energy gears back at them. Rogue turned to Grease and apologized for arriving late before engaging the Washio brothers, overpowering them before he performed a Crack Up Rider punch on Engine Bro's, easily defeating the white Kaiser. Even when Remocon Bro's transformed into Hell Bro's, Rogue was able to block his attacks and counter before executing a Crack Up Rider kick, sending Hell Bro's flying off the second floor and forcing both Washio brothers to retreat. As Evolto commended him for joining Grease and Ryuga before transforming into Kamen Rider Evol Cobra, Rogue engaged the alien rider, telling Evol he won't allow him to take over Japan. As Evol asked him if he's attempting to take his late father's place, Rogue admit he's not capable of taking his fathers' role, but he admit he can help build up for those who are and vow to fight for love and peace before calling Grease to assist him, which the Hokuto rider obliged. Both Rogue and Grease had the upper hand until Evol transformed into Evol Rabbit and turned the table against Rogue and Grease, using Grease as a shield to block Rogue's attacks until he kicked Grease off the upper floor. Rogue then found himself overwhelmed as he wondered how Evol acquired his new power until he spotted Ryuga attempt to assist, but Evol tossed him aside, unaware that Ryuga took the Dragon Evolbottle, before continuing his assault on Rouge and held him in place with his energy while he executed an Evoltic Rider punch, sending Rogue flying to Grease on the lower floor.
Recovering, Rogue and Grease saw Ryuga, who managed to amplify the small traces of Evolto's genes in his body, readminister Nebula gas in his body with the newly Great Dragon Evolbottle and transform into Kamen Rider Great Cross-Z, forcing himself and Evol to the lower as they traded blows with one another. Rogue and Grease watched the fight, even with Cross-Z's new form, Evol overpowered him until Cross-Z transformed into Cross-Z Magma, turning the tables. As Cross-Z Magma overpowered Evol with his new strength and executed a series of Volcanic Rider punches, Rogue and Grease joined the fight as all three riders executed their Rider kick attacks and flew at Evol, who placed the rusted Evol-Trigger in the kicks' path, which then absorbed the energy from the attacks to restore itself and turn to its original black and white color scheme before casting an energy wave to send the three riders back. Rogue watched as Evol activated the black trigger, which generated a black cyclone that sent Rogue flying away with Grease and cancelling their transformations. Rising back tot their feet, Gentoku and Kazumi saw the cyclone disappear to reveal Evol's true form: Kamen Rider Evol Black Hole.
During the Build Annihilation Plan, Rogue attempted to protect Sento Kiryu from the amassed populace of Japan, who had been compelled to eliminate him, only to be overwhelmed by the angry mob. Along with Kazumi, Gentoku was stripped of his Sclash Driver and kept in confinement before being set free by Utsumi, who made them beg him to return their Drivers. Making their return, Grease and Rogue defeated both the Scissors and Zebra Lost Smash while the leader of the Blood Tribe was defeated by Cross-ZBuild.
Final Battle and Death
Evolto shows up to the Nascita members while using Soichi persona. He bid them farewell and announce the end of the earth before transforming into his Black Hole Form. Although still badly injured after the battle with Clone Hell Bro's, Gentoku nevertheless decided to keep fighting with Sento and Banjo as they transformed into Rogue, Build Genius & Cross-Z Magma respectively. However, Evol is still too strong to handle as he finally gained all 10 Lost Fullbottles and used it to become Monster form once more. Evol used his power to first destroy the moon and perform the Black Hole Break on Earth, thus enhancing his power even further. Things goes from bad to worse as Gentoku's body is also reaching his limits, and starts disintegrating.
After Sento and Banjo are knocked out from their respective transformations, Rogue decides to Fight Evol all by himself. Rogue keeps aiming for Evolto's Evol Trigger despite their huge gap in Hazard Level. Gentoku exclaimed that he had made a promise to Kazumi to wage their lives as Kamen Riders, and also asks him if he now becomes more like his dad. Kazumi states that he had forgiven Gentoku from his actions when he was still with Seito and exclaimed that Gentoku is doing fine with following Taizan's peaceful approach. Gentoku gallantly proclaimed that he'll protect the future of Japan, although he's having hard time in defeating Evol.
An annoyed Evol managed to break part of Rogue's helmet, reminding him that with Gentoku's current Hazard Level, he didn't have the slightest chance to defeat him. Just as before Rogue fell unconscious, he heard the cry of the citizens, begging for the Kamen Riders to save them. Gentoku's determination managed to rise his Hazard Level which surprised Evol.
In a final gambit, Gentoku attacks Evol with a desperate Rider Kick, but to no avail as Evol easily brushes the Rider aside into a nearby pillar. Having exhausted the last embers of strength he had left, Gentoku, in a surprising yet poignant plea, entrusts Sento with defeating Evolto as he begins disintegrate once more.
In his last moments, Gentoku ponders if he had lived up to the legacy of his dad before dissolving into a cloud of purple Nebula Gas.
Thanks to Gentoku's persistence, Evol became paralyzed as Rogue's last attack managed to break the Evol Trigger apart. This allowed Sento to extract the Black Pandora Panel and the 10 Lost FullBottles from Evolto, and fuse them with the White Pandora Panel, opening the path for the New World and completely ruining Evolto's End Game. A vision of Gentoku appears as Banjou encouraging Sento as he had his final battle against Evolto.
After Sento defeats Evolto for good, the new world had been successfully created. This world’s version of Gentoku is still working with his dad as an aide and briefing him about the schedule for that day. Gentoku then meets Sawa, now a Central Politics and Economics journalist and asks her if they could continue the interview in his office, which Sawa agrees.
Kamen Rider Heisei Generations FOREVER
- "One of our objectives is to create the ultimate life form. I wonder what would happen if someone who was injected with the Smash element underwent experimentation again. I'll have to run a test."
- ―Gentoku, as Night Rogue, shows his malicious nature[src]
- "I knew nothing...I survived by trusting only my ambitions. But alone, I was just a piece of trash that couldn't do anything. That's why I...took my great pride...took my vanity...and threw away everything to be reborn."
- ―Gentoku, as Kamen Rider Rogue, showing his soulless nature after being reborn.[src]
Gentoku is a composed and generally calm man, rarely changing his tone of voice unless agitated. Underneath his cool exterior, he is a man with questionable morals at best: he flirted with a journalist, and referred to Ryuga Banjo and Sento Kiryu as toys, as well as his fiery temper whenever he commands his soldiers. During a conversation with Gentoku, Blood Stalk reveals that Gentoku's goal is to mass produce Kamen Rider technology from his experiments for military use. Gentoku is determined to see this project succeed and will do everything he can to silence or stop anyone who will interfere with this plan. He also didn't hesitate to kill his decoy with his own hand to get press in his favor.
As Night Rogue, he is a malicious control freak. Seeing innocent people as mere guinea pigs, he doesn't hesitate to experiment on them, even when fully knowing that his subjects would be too weak to survive. Despite his cold and calculating personality, Gentoku has his own standards and shows little to no tolerance with insubordination. He is easily vexed each time Blood Stalk goes against his orders, which drives a wedge between their collaboration. He is also appalled when Stalk put his father to the hospital for the second time before Taizan was about to resume his duty as Prime Minister.
It is likely that his negative personality traits are a result of his exposure to Pandora Box during the Skywall disaster. This has caused his original ambitions to be perverted, believing that military force is the only way to unite the country. His father highlighted this as well, remembering how Gentoku used to be the kind person he was before the incident. Gentoku is susceptible to episodes of paranoia and aggression, urging his father that they need a military to crush Seito and Hokuto before they crush Touto, believing they are out to get the capital and superior military might can stop their advance. Eventually, his father disowned him due of his plan to invade Hokuto.
Ultimately, his actions of taking over Taizan's place as Touto Prime Minister led to his father exiling him from Touto. Following his exile and affiliation with Seito as Kamen Rider Rogue, Gentoku's malicious personality takes a nihilistic turn. He gave up everything else for the sake of strength, to the point he would go into further heights to be subjected with cruel experimentation. Having experienced 'Hell', where he was looked down and tortured, Gentoku become somewhat emotionless, no longer the hotheaded control freak that he was once. His ambition now is to destroy Touto and 'bring order' on Japan as whole. While he's shown to understand the burden of it, he has also proven to be more cruel and ruthless by killing Akaba without compassion.
Before becoming Kamen Rider Rogue, Gentoku had a habit of rubbing his beard with his fingers. After becoming Kamen Rider Rogue, he has become a brutal fighter such as using sure-kill attacks and grabbing Build by the eyepiece of his helmet.
Gentoku, despite his nihilistic disposition, remained skeptical towards Namba Heavy Industries' plan with the Pandora Box. Juzaburo Namba's (under the guise of the late Mido) intentions to use the box to create an immortal Namba Empire contradicts Gentoku's own ambitions with the box, to the point he warned Sento about Namba masquerading as Mido. At the same time, Gentoku was being kept under Namba's leash and they would not hesitate to kill him if he acted behind Namba's back. He is quick to detest Namba's underhanded tactics, such as holding Kazumi Sawatari's farmers hostage to blackmail him into betraying the Touto government. Gentoku placed himself in mortal danger to free the captives, resulting in Utsumi activating the killswitch device to punish Gentoku for his defiance.
Eventually, Evolto revealed that due to Gentoku's increased Hazard Level, Gentoku's aggressiveness and power-hungry nature is nullified, returning him to the man he was before the Sky Wall incident. Gentoku planned to play the villain in order to solidify Japan under Taizan's peaceful approach and rebuild Japan as whole, without concern for internal borders. Despite the strained relationship between father and son, Gentoku shows to care for his own father in spite of focusing on his own ambitions. It comes to a full circle when he attempted to free Taizan from Evolto's clutches. His father, in return sacrificed himself to ensure Gentoku's survival.
Outside of political business, Gentoku seems to take a liking towards the retro. As seen from his karaoke sessions, he has a preference for songs from the past (somewhere around the 1980s). nascita, a far cry from his villainous get-up, has attracted the shock of everyone, as well as the disgust of Misora. Eventually, he toned down his gaudiness after he get himself a Leather Jacket, but he would occasionally convey messages via the shirt he wears within his jacket, which he seems to be able to change at will. Apparently, Gentoku also hates Bell Pepper and can't afford a Train Ticket on his own, thus he usually go to a far place on foot.Also, his odd, retro-inspired casual clothes during his stay with
Powers and Abilities
- Hazard Level 4+: According to Gentoku as Night Rogue, his level was stated to be above Hazard Level 3, but due to the Transteam Gun's limitations, his Hazard Level becomes capped and does not reflect his actual level. Sometime after being exiled from Touto, Gentoku underwent cruel experimentation in order to raise his Hazard Level to above 4 in order to utilize the Sclash Driver.
- Nebula Gas Shockwaves: Prior his debut as a Kamen Rider, Gentoku was able to unleash shockwaves which can reduce Guardians into nothing. The principle of it is currently unknown.
- Hand-to-Hand Combat: Though briefly, he was seen to easily block and counter Ryuga Banjo's punches, who himself was a professional fighter.
- Kill Switch (Formerly): Due to his alliance with Seito, he has a chip inside of his chest that could detonate if he showed any signs of betrayal. The chip is also capable of emitting a a painful electric shock, triggered by Utsumi's device that can force Rogue out of his transformation. It seems Utsumi's device is able capable of setting the level of electric shock that Gentoku receives, and if Utsumi switch is broken, Evolto had a spare switch. With Sento's help, this chip was deactivated.

In addition, the white crack-like segments are actually durable reinforced frame pieces. Rogue is also armed with the Fanguard Shoulder (ファンガードショルダー Fangādo Shorudā) armor pieces.
His helmet's most distinct feature is the two crocodile jaw Cell Face Crusher ( セルフェイスクラッシャー Seru Feisu Kurasshā). During transformation, the Cell Face Crusher cracks the helmet open, revealing the Hard Jelly Eyes (ハードゼリーアイ Hādo Zerī Ai).

- Sento Kiryu/Takumi Katsuragi: Gentoku knew Sento back then as Katsuragi. When Takumi returned as Sento, he didn't recognize him only just another stranger who he hired to research on Pandora's Box. Eventually, learning the truth from Stalk that Sento was Takumi, he immediately called him by his true name. Becoming from Night Rogue to a Kamen Rider, the Nebula Gas changed him back to his normal self from Pandora's Box's light.

After the birth of Evol on Earth, Kazumi fought with Gentoku to make him fight alongside Team Build and to pay him back for not only Akaba's death, but also for his former compatriots killing Kiba and waging war on Hokuto during his time in Touto. Defeated, Gentoku fights alongside them when freeing Sento from Evolto's control. Kazumi is annoyed with Gentoku's retro fashion.

Utsumi desired revenge on him for all the life of hell he's been put through. Hearing Gentoku banished from Touto, gave him the opportunity for payback, when Gentoku demanded him and Nanba to make him a rider for Seito. When Nanba was killed by Evolto, choosing to serve him, Utsumi's vengeance on Gentoku grew when becoming Mad Rogue. He revealed himself to be getting revenge for Nanba's death along with being reborn a cyborg due to Gentoku's actions in his final days.
- Juzaburo Namba: Once served under him before joining Seito, during his time in Touto. Now later enemies after realizing the situation he's in after Nanba replaced Mido as him.
Behind the Scenes
Gentoku is portrayed by Kensei Mikami (水上 剣星 Mikami Kensei). As Night Rogue and Kamen Rider Rogue, his suit actor is Jun Watanabe (渡辺淳 Watanabe Jun), who played Secondary Riders since Kamen Rider Drive.
Night Rogue's name is formed from the English words “Night” and “Rogue.” The name as a whole seems to be a pun of the word “Nitro”, possibly referencing Night Rogue’s Steam Engine Motif.
His Rider name, Rogue, while borrowing part of his previous Form's name, is appropriate to his current status as a defector from Touto, as well as defining his behavior up to his introduction as a Rider.
- Gentoku is similar to Kuroto Dan from the previous season as both were first introduced as allies were later revealed to be the identities of prominent antagonists (Kamen Rider Genm for Kuroto and Night Rogue for Gentoku). Also, while in their alter-egos they fight the Kamen Riders, in their true identities they pretend to aid them to secretly study them for their purposes (Kuroto studied the evolution of his first four Kamen Riders for the completion of Kamen Rider Chronicle while Gentoku is not truly interested in studying any evolution of Build, he does it under Blood Stalk's influence to create Kamen Riders for military purposes). Additionally, to fool the main rider, both of them used a decoy to prevent their own identity from being exposed (Parado as "Genm" (though not transformed), and Nariaki Utsumi as Night Rogue).
- Coincidentally, both were characters that were revealed to be the true identities of antagonists, who do not transform in their respective Heisei Generations movie (VS Dr. Pac-Man for Kuroto and FINAL for Gentoku).
- Later, both former 'decoy' took revenge to their former 'boss' (Parado by killing Kuroto using Bugvisor loaded with Dangerous Zombie gashat and Utsumi by trampling Gentoku hand as he kneel, laughing sadistically while doing so).
- Unlike Kuroto, however, Gentoku embodies a "knight templar"-type of lawful evil because of his fears of the neighboring rivals trying to attack Touto, and hence his aforementioned goals of using the Rider systems for war.
- They both have black and violet Rider form.
- They both joined the fellow Riders which they are in shades of yellow (Kamen Rider Lazer/Turbo (yellow) and Kamen Rider Grease (gold).
- As series go on, their personality would change to be more comical character of main Rider's side. e.g. Kuroto calls himself "God" while Gentoku usually answers other with his shirt by unzip his jacket.
- Gentoku also shares a few similarities to Chase in that they both started out as Rider-like generals that transformed with a gun before becoming proper Riders by using their respective series' second transformation belt.
- Though Chase redeemed himself after becoming Kamen Rider Chaser, Gentoku initially remained malicious after becoming Kamen Rider Rogue. However, he also eventually joins forces with his series' main Rider as well.
- Gentoku's personality after becoming Kamen Rider Rogue is much more like Kaito Kumon during the Forbidden Fruit Saga of Kamen Rider Gaim, especially after becoming Lord Baron. Both will go in desperate heights in obtaining a greater power - Kaito desires to claim the Forbidden Fruit and remake the world where the weak will never be trampled by the strong, Gentoku plans to seize the Pandora Box so he will reunify Japan with his own hands.
- Gentoku is also similar to Alain when both are being protected by their dying fathers in order for them to live, and in turn they eventually redeemed into heroes.
- He is a Kamen Rider-like villain and the main Rider's arch-enemy similar to Shadow Moon and Chase (when the latter was still Mashin Chaser).
- Night Rogue's bat motif, along with Blood Stalk's cobra motif, is part of the recurring bat/cobra/spider trio in the Kamen Rider franchise, a tribute to the first two Shocker monsters as well as the first monster to be upgraded.
- Night Rogue's outfit design is similar to Kamen Rider Kiva, and his color scheme is similar to Kamen Rider Arc's color scheme.
- Night Rogue's undersuit inexplicably changes from black to brown in later episodes, especially during fighting scenes. In episode 19, the undersuit briefly turns back to black in one scene.
- As Night Rogue, his kick with his wings is similar to Kamen Rider Knight's Final Vent.
- As a slightly humorous nod to his "crack" motif, Kamen Rider Rogue has a fragile warning label pasted onto the back of his helmet.
- Incidentally, his helmet does literally crack in episode 48, as Rogue's left eyepiece breaks.
- Nariaki Utsumi - The second Night Rogue and Kamen Rider MadRogue
