|This article is about a rider in Kamen Rider Kiva.|
Wataru Kurenai (紅 渡, Kurenai Wataru) is the main protagonist of Kamen Rider Kiva. He is the half-human/half-Fangire child of Otoya Kurenai and previous Fangire Queen Maya, inheriting the mantle of Kamen Rider Kiva (仮面ライダーキバ, Kamen Raidā Kiba, Masked Rider Kiva) to protect humanity while uncovering the mysteries that surround his family legacy.
Left by Maya as a child to protect him from the retribution she would face, Wataru lives in a European-style manor owned by Otoya, having inherited the building. With Kivat-Bat the 3rd as his sole companion, Wataru lived a lonely childhood, being regularly bullied by others.
One day, an older boy named Taiga helped Wataru from his tormentors, leading to their friendship. Since then, the two regularly played at a park, until Taiga mysteriously disappeared at some point.
By his early twenties, Wataru has become Kamen Rider Kiva, fighting any Fangire menaces detected by the Bloody Rose. Like his father, Wataru also showed superb skills with a violin, in both craftsmanship and musical performance. Earning money with these talents, Wataru gained a disciple in Shizuka, the latter growing affectionate of him.
Still reeling from his hardships however, Wataru spent most of his time as a shut-in, donning a mask and glasses to protect him from the "world's allergies" and using a notebook to express himself without talking. Combining these strange mannerisms with rumors of his family, most of Wataru's neighbors referred to him as Obaketaro (お化け太郎, Obaketarō, literally "Ghost Boy"), disliking Wataru entirely.
The Wonderful Blue Sky Organization
In 2008, while gathering fish bones in a third attempt to create the ultimate varnish for the ultimate violin like his father, Wataru comes across Megumi Aso, who manages to show him that his "allergies" are all in his head. He later saves her from the Horse Fangire as Kiva, countering her attempt to kill him soon after before leaving her stupefied and later saving her a second time from the Octopus Fangire.
During the events of Climax Deka, Wataru helped Ryotaro Nogami during his fight against Nega Den-O and the Nega DenLiner.
When a female lawyer named Aya Natsukawa arrives at Wataru's home with a list of the various people that Otoya had victimized with his antics, Wataru is devastated to know a side of his father his mother never told him. After meeting Keisuke Nago and getting his advice, Wataru performs acts of moral obligation for his father's sins, until he learns that Natsukawa is the Moth Fangire and Otoya's most wounded victim. Unable to fight her, Kivat is forced to summon Garulu to supplant Wataru with his feral rage in Garulu Form so Kiva can kill the Fangire.
When Nago requests that Wataru keep an eye on Megumi in his stead, he meets a young man named Noboru, who is obsessed with Megumi himself. When Noboru reveals himself to be the Sheep Fangire, Wataru learns of Nago's hatred towards Kiva. Saddened but undaunted, Wataru manages to rescue Megumi when she is captured by the Sheep Fangire, destroying him in Basshaa Form. Since the incident, Wataru took to heart what Megumi learned from her mother: the same ideology Otoya follows: "All humans are music". Eventually, Wataru is forced to lose all of Nago's respect for him when he tries to protect the Frog Fangire, Takeo Ōmura. However, Wataru did learn from Ōmura that he needs to make a violin to call his own.
It was later that Wataru meets Kengo, whose rock and roll helps him in becoming more confident in himself. Though Wataru and Kengo have separate dreams, the two promise to help the other out so that both their dreams come true. Wataru ensures his part by protecting Kengo from the Rhinoceros Fangire, accessing Dogga Form. However, Wataru's world is turned upside again when he encounters the Lion Fangire Rook, whom he met when he was suffering amnesia. However, by meeting Mami Kurasawa, a former student under his father (of which he is unaware), Wataru learns to cope with the recent Fangire events of who's evil and not by "listening to the voice in his heart."
After begrudgingly following Kengo to a fortune teller to find out who Kiva really is, Wataru loses consciousness. When he awakens, he is more confident in his abilities but has a very sarcastic attitude. It is revealed that he is possessed, albeit unknowingly, by his father Otoya as a result of the fortune teller's ritual. While using Wataru's body, although unable to maintain possession at times, Otoya teaches Megumi how to overcome her fears of using the Ixa Knuckle and she is able to help Ixa defeat the Ladybug Fangire. When Otoya finally leaves, Wataru has no recollection of what has happened under the influence of his father's spirit.
Soon after this, at a mixer that Kengo set up, Nago has a waitress named Mio fired for accidentally spilling ice cream on his shirt. Feeling sorry for her, Wataru runs after her and finds out that they have a lot in common and they start dating Megumi's help. However, when a berserk Grizzly Fangire tries to kill Mio, a rage awakens within Wataru that releases Tatsulot from Castle Doran who unleashes Kiva's full power, changing Kiva into his Emperor Form to mortally wound the Fangire. Before Mio took her leave, due to personal issues, Wataru promises Mio that he would get stronger for her. While the Fangire Hunters were being arrested, Wataru remembers Taiga and decides to help them out by him and Kengo joining the Fangire Hunters to battle the Crab Fangire until Nago altered history so that the Cicada Fangire's survival negated the Fangire Hunters' crisis. But in the aftermath of the fight against both Fangires, Nago learns that the button he gave to Maya ended up in Wataru's possession, explaining it to be an heirloom from his mother, setting up the events where Nago learns that Wataru is Kiva.
The fight's aftermath also caused a falling out between Wataru and Kengo when the latter's hand was injured to the point he could never play again and Wataru was trying to keep the truth from him out of not wanting him to worry. Later, Wataru is face to face with a fully grown Taiga, only to be devastated after learning that he and Mio are engaged. This stress, augmented by Kengo's return as the new Ixa user, causes the Bloody Rose to crack. Though he finishes repairing the violin, he realizes something is missing from the Bloody Rose. Then, Jiro appears to him, revealing to Wataru that his father's desires dwell within the violin. When ambushed by a Kukulkan while fighting the Horsefly Fangire, Kivat holds the monster at bay as Wataru plays the Bloody Rose, realizing his father's desires to protect all music. Infusing the violin with his own desire to find his own music, Kiva finally awakens into Flight Style to destroy the Kukulkan. However, this event causes the evoking of a weapon within Castle Doran, the Zanvat Sword of the previous King of the Checkmate Four.
Eventually, Jiro brings Wataru into Castle Doran to pull out the sword. When he discovers that he can't pull it out, he finds Mio running towards him until she is knocked out by the Rat Fangire. After destroying one, he is ambushed by two others before having to fight Kamen Rider Saga. Escaping, he finds Mio, who tells him that she loves him, not Taiga. Wataru becomes happy after this event until he receives an invitation to Taiga and Mio's wedding. He then appears before Mio and Taiga, defending them from more Rat Fangires, while admitting his feelings to Mio. Found by Jiro, he tries to pull out the blade again, succeeding, though the Zanvat is created to limit the sword's power when it causes his Fangire blood to surface. After a brief fight with Saga, Wataru is exposed by Mio as she is revealed as the Pearlshell Fangire with Saga reverting to Taiga. Wataru runs off in confusion and hysterics before being spirited by Jiro who helps him cope with the revelations. The next day, as he and Mio discuss this, Taiga takes them to meet Maya as Wataru recognizes her. While demanding why she left him to fend for himself, Wataru learns that he is Taiga's younger half-brother.
Although confused as to why Maya never told him about any of this, Wataru slowly accepts his true identity. Wanting to share the truth, he informs Nago that he will tell everyone in the organization that he is Kiva. When Nago arranges a gathering at a restaurant, Wataru also reveals that he is half-Fangire, shocking everyone. Despite this, Shima falsely promises to help him build a world where both Fangires and humans can coexist peacefully.
Later, Wataru is approached by Taiga, who asks him to join the Fangires, and Mio, who asks him to destroy Taiga so he can be the new King. Wataru declines both of these requests, perplexed as to why both sides cannot get along. However, Taiga is persistent in getting his friend to understand his ideology that he asks the Bishop to awaken Wataru's true Fangire powers. This causes Wataru to go berserk and attack his friends, even to the extent of nearly killing Megumi. When he finally returns to normal, he becomes so traumatized from the ordeal that he completely relapses back into a recluse and completely isolates himself within his house, refusing to fight as Kiva anymore.
Though being convinced by Kengo and Nago, it took Maya's intervention to convince Wataru to fight as Kiva again, not as a human or a Fangire but as himself, so that he'll find his own music. Taiga, enraged by Wataru's decision, gives him time to reconsider. When Shima was near-certain death, Taiga saved him by transplanting into him a bit of Fangire power. Wataru is appointed as Shima's bodyguard when this is revealed, as Nago was unable to bring himself to kill Shima. Shima then dies in combat with Taiga, enraging Wataru. They battle, and just as Kiva was about to finish Saga off, Mio steps in the way and takes the Emperor Moon Break as she is destroyed. However, finding her after the Bishop fatally wounds her, Wataru is left to think that he killed her and goes into despair with an equally distraught Taiga intent on killing him under the same impression.
But Jiro's interference allows Wataru to go back into 1986, meeting his father face to face just before he dons the mantle of Kiva. Though he originally came to keep his parents apart to negate his existence, Wataru learns that it would be pointless if Mio had never met him and the only way he could honor her is to live a strong life for her sake. He would ultimately play a pivotal role in the death of the original King before returning to 2008 after receiving his father's final words. With a stronger resolve, he charges into battle against the revived Fangires unleashed by the Bishop, saving Shizuka, Megumi, and Nago before confronting Taiga to settle things. In spite of interference, the fight ends with Wataru the winner though he refused to kill Taiga as he take his brother's place as the new King of the Fangires to everyone's shock. Taiga later demands Wataru to fight him again, having claimed to kill their mother to acquire the powers of Dark Kiva.
After their fight is interrupted by the Bishop and his new army of revived Fangires, the two Kivas and the Arms Monsters quickly defeat the Fangires, as the Bishop is destroyed by Nago as Rising Ixa. Wataru reveals that he had taken the mantle of the King for his brother's sake, shielding him from his enemies. By then, the revived Bat Fangire attacks the two brothers, defeating them easily. Wataru is thrown off of a cliff and encounters the spirit of his father near the discarded gauntlet of the original Ixa Prototype, telling Wataru that he lives on inside him and not to lose hope. With his father's encouraging words, both he and Taiga are able to defeat the Bat Fangire with a Snaking Death-Break and Emperor Moon Break combo. When Maya appears, Wataru is put at ease knowing that she was not really killed by Taiga as the two brothers are now on the same page and resume their fight to determine the victor.
Days later, just as he is about to play the violin at Nago and Megumi's wedding, a young man resembling Otoya bursts into the reception claiming to be Wataru's son Masao Kurenai from 22 years in the future. He warns his father of a new threat to humanity and shows him, Taiga, Nago, the Arms Monsters, and the rest of the reception a portal in the sky. Immediately in response to the situation, Wataru transforms into Kamen Rider Kiva Emperor Form. With his son as Kamen Rider New Kiva, Nago as Kamen Rider Ixa Rising Form, Taiga as Kamen Rider Dark Kiva, and the Arms Monsters at his side, Wataru confronts this new foe.

Kamen Rider Kiva: King of the Castle in the Demon World
In the movie, the story begins in 2008 as the Antlion Fangire begins to feed at an exhibit room until Megumi intervened as Nago arrives to slay the monster. However, during their struggle, the Mummy Legendorga suddenly resurrects and feeds on the humans before using his power to turn the Antlion Fangire into his slave to aid him in overwhelming Nago with the Arms Monsters watching the fight. While this occurred, Wataru Kurenai starts attending a local high school at Shizuka's suggestion after a welfare officer visited him and quickly befriends Natsuki Tsukue, who tries to get Wataru to join several clubs where he fails in each one while trying to ask her if she would like to start a violin club after hearing her play, she refuses outright.
When Nago finds Sugimura, he chases the fugitive all the way to Wataru's high school and takes Natsuki hostage, but she is freed by the joint efforts of Wataru and Nago. However, the Medusa and Mummy Legendorgas appear to Sugimura's aid when he was being escorted back to jail, overpowering Ixa as Kiva arrives. They overpower the riders until another figure named Takato Shiramine appears, transforming into Kamen Rider Rey and driving the two Legendorgas off as they take Sugimura with them, waking him as their Lord.
Wataru asks the Arms Monsters permission to use Castle Doran's Time Door to go back in time to prevent Sugimura's actions. While trying to get Sakakibara to cancel her concert, he is stopped by Otoya who was convinced he was a Fangire and tries to beat him. After another attempt to talk to her, Wataru is attacked by Yuri after Otoya tells her about him as the police arrive to arrest Otoya on the impression he's the criminal. Forced to take Wataru in a stolen police car, Otoya is shocked when Wataru recognized him as his father. Wataru attempts to prove himself with his cellphone and money before he and his father are both sent to Kanto West Prison where Towa is to perform as Sugimura takes her hostage to escape. But Otoya knocks out a guard named Sanjou so he and Wataru can get out of their cell to save Towa and restrain Sugimura.
After Wataru returns to his time under the impression he succeeded, Sanjou turns out to be the Zebra Fangire that attacks Otoya before trying to kill Towa. When Wataru returns to his time, he is targeted by people under the control of the Mummy and Medusa Legendorgas, with the Gargoyle Legendorga overseeing their attack.
Otoya is enjoying the present and its perks after disguising Wataru so he wouldn't be attacked, meeting up with Shiramine before he is distracted by a young woman named Sayaka as Shiramine tells Wataru that Kiva's destruction will soon come as Sayaka reveals herself as the Medusa Legendorga.
Becoming Kiva to fight the Legendorgas, he summons Buroon Booster which he uses to destroys the Mandrake Legendorga as the Arms Monsters arrive to aid Kiva in fighting the remaining three in both their true forms and in their weapon forms. However, as his friends drive the monsters off, Kiva is attacked by Rey who reveals that he is on the Legendorgas' side as he then takes the Aso girls hostage, Rey-Kivat arrives with orders to take Wataru to the Legendorgas' castle. After knocking his father out, Wataru arrives at the castle and is brought before Sugimura, who reveals himself to be the vessel of the Legendorga Lord Arc who was defeated by the original Kiva and uses his power to force Wataru's Fangire blood to manifest into Kiva's Flight Style. Under Arc's control, Wataru is forced to have Otoya relinquish his Ixa Knuckle as Nago arrives to help, use their time-respective Ixa Knuckles to fight the Legendorgas with Otoya managing to snap his son out of Arc's spell.
Enraged, Sugimura decides to kill Wataru as they both assume their Rider Forms. While this occurred, Kiva is forced to assume Emperor Form to deal with the larger opponent, weakening him enough so he can be defeated by both of the Kurenai family Riders. However, Arc absorbs the power of the Legendorga race by sucking the eye on the moon into himself to become Legend Arc to kill them. Kiva then transforms into Emperor Form's Flight Style to fight Legend Arc in a battle across the city, until Castle Doran comes to Kiva's aid, finally allowing Kiva to perform a Rider Kick with enough force to slam Arc into the moon, leaving a gigantic crater and destroying him for good. After everything returns to normal, Otoya performs alongside his son on their violins at Wataru's school before he and Yuri return to their time. Once they left, Wataru is joined by Natsuki as the two perform a duet.

Kamen Rider: Battride War Genesis
Kamen Rider Kiva reappeared in Kamen Rider: Battride War Genesis.
Kamen Rider Kiva is a playable character alongside the other Kamen Riders.
In the novel reimagination of the TV series, Kiva is Wataru's Fangire form. With that, Kivat, Basshaa and Dogga do not exist in this story. Meanwhile, Jiro/Garulu, who is in turn, a Fangire Hunter. And Nago never befriends Wataru, who ends up as the final villain. He died after his Rider Kick collides with Wataru's kick.
Wataru Kurenai is a polite individual with a gentle soul. From the mystical powers inherited by his mother, Wataru has an exceptionally powerful sense of empathy, to which influences his overall perception of others.
Since childhood, Wataru showed himself to be quite timid and emotional, shedding tears in moments of distress. Growing up as an lonely orphan also significantly impacted Wataru in adulthood, leading to a lack of social skills in general. Being widely disliked by his rude neighbors, Wataru is shown to crave companionship, no matter how obnoxious the person may be. Combined with an inability to withstand peer pressure, he is subservient to the whims of others, an issue which Wataru himself is well aware of.
Despite his polite demeanor, Wataru is also quite unobservant towards people, earning their ire on several occasions. His attempts to ease the distress of others can unintentionally worsen the problem at times, further upsetting the person by accident. In such cases, Wataru often believes himself to be at fault completely, no matter how unreasonable the retribution he may receive.
In his everyday life and as Kamen Rider Kiva, Wataru's weak will can severely hamper his prowess at times, becoming unable to function properly in such states. Similarly, due to his primary motive for fighting being a form of instinct triggered by the Bloody Rose, Wataru's focus is easily broken when stressed, retreating from his battles in such situations.
Slowly though, as he continues to widen his social circle, Wataru starts to mature more as an individual, gradually losing his self-conscious nature. This would allow him to better socialize with others, calmly handling his neighbors' unkindness without trouble. Both Kivat-Bat the 3rd and Shizuka themselves have noted this, recognizing that Wataru no longer behaved as a shut-in like before.
However, though no longer as weak-willed as before, Wataru could still succumb to sorrow at times, initially attempting to avert his eyes from reality once learning of Mio and Taiga's identity as Fangires. Furthermore, when learning of his own heritage as a half-Fangire, Wataru became distraught with himself, questioning the reason for fighting as Kiva. When Bishop temporarily overtook his mind, Wataru's despair increased, leading to him becoming a complete shut-in.
From his friends' actions and Maya's encouragement though, Wataru grew to accept his hybrid nature, fully believing that humans and Fangires can co-exist with one another. Attaining the trust of the Wonderful Blue Sky Organization, Wataru found himself alone no more, having the companionship he craved since childhood. Even then, Wataru never stopped caring for Taiga, being unable to fully oppose him as opponents.
When it seemed Taiga had killed Shima though, Wataru was consumed with anger, to the point of nearly killing him in their duel. When Wataru's Rider Kick accidently struck Mio instead, Wataru's anger immediately turned into devastation. Blaming himself for Mio's death, Wataru became suicidal, with grief consuming him.
Once sent to the past by Jiro, Wataru immediately attempted to split his parents apart, in hopes of negating his existence entirely. After fighting alongside his father, however, Wataru recognized that Mio would never wish for his own death, and that he should honor her memories by continuing to live his life. After his victory against the Fangire King, Wataru significantly matured as a person, with his father's words and selfless sacrifice teaching him to be more confident in himself.
Adopting his father's ideology that "All humans are music", Wataru's stance as Kamen Rider Kiva changes substantially, with his newfound goal being to protect all those in need.
In Kamen Rider Decade though, Wataru is portrayed as a highly ruthless figure, a stark contrast to his original characterization. Showing no care what happened to the A.R. Riders or Tsukasa Kadoya/Kamen Rider Decade, Wataru voiced his intent on bringing forth their deaths, stating it to be necessary for restoring the Rider worlds. Even after seeing Natsumi Hikari and the others in distraught at losing Tsukasa, Wataru showed no sympathy whatsoever, opting to simply explain the situation to them in a cold and distant manner.
Powers and Abilities
- Hybrid Physiology: Due to his half-Fangire high-born heritage, Wataru has immense potential, possessing powers no full blooded Fangire has. However, his lack of confidence prevented Wataru from fighting to his fullest or even doing more than six push-ups. As Otoya showed though, Wataru's body is in perfect shape, capable of easily defeating three thugs with no trouble. Evidently, when controlled by the Zanvat Sword, Wataru proved powerful enough to overwhelm Jiro, Ramon, and Riki in human forms simultaneously.
- Psychic Powers: Similar to his mother, Wataru possesses a number of mystical abilities, such as extrasensory perception and aura manipulation.
- Reality Warping: In Kamen Rider Decade, Wataru somehow gained the power to warp reality itself, stopping time with a simple finger snap.

Kamen Rider Kiva is composed of the following parts:
- Kiva Persona (キバ・ペルソナ, Kiba Perusona) - The head.
- Demon Emperor Stone (Blue Stone) (魔皇石 (碧石), Ma Ō Seki (Ao Seki)) - The blue-green jewel on the forehead. It amplifies Kiva's Demon Emperor Power (魔皇力, Maou Ri~yoku) by several to tens of times. In this world, a blue Demon Emperor Stone is much more valuable than a crimson/red Demon Emperor Stone (such as those found in Kiva's Arms Weapons). It can accumulate and amplify demonic energy and serves as a restraint to prevent the demon energy from exploding.
- Guardian Crown (ガーディアンクラウン, Gādian Kuraun) - The red 'bat head'/guard plate section on the forehead that houses the Demon Emperor Stone. It serves to protect the Demon Emperor Stone. Its red coloration is due to the Demon Emperor Stone's influence.
- Crown Sonar (クラウンソナー, Kuraun Sonā) - The red sections on top of the Omni Lens. Its coloring is due to the influence of the Demon Emperor Stone. This crimson crown can emit ultrasonic waves to utilize echolocation to grasp surroundings if Kiva's view is obstructed. In can collect information such as enemy position up to 5000 meters away.
- Coolant Silver (クーラントシルヴァ, Kūranto Shiruvu~a) - Silver sections embedded behind the Crown Sonar. They are cooling boards that prevent the user's brain from being destroyed due to the vast amounts of demonic power amplified by the Demon Emperor Stone. It is made of Trysilvania Silver (トライシルバニア銀, Toraishirubania Gin), which has the power of silver (銀の力, gin no chikara) to suppress demonic power from exploding. It has five heat-dissipating ducts on each side of the head to cool down heat energy swirling within the hemet.
- Omni Lens (オムニレンズ, Omuni Renzu) - The eyes. They are visual amplification devices that can obtain visual information at a distance of 500 meters forward and at a 220° angle. It also has an X-ray function that allows Kiva to see through 10 meter-thick steel plating. A nanoscope function is also incorporated, allowing Kiva to detect extremely small objects such as bacteria.
- Wild Nose (ワイルドノーズ, Wairudo Nōzu) - An olfactory amplification device located between the eyes. It gives Kiva detection abilities equivalent to a dog's, allowing Kiva to obtain a sense of smell one million more times than a human. The Wild Nose can track a Fangire's location by sniffing out their odor and footprints.
- Omni Phone (オムニフォン, Omuni Fon) - Hearing amplifiers. Its sensitivity can be raised according to the wearer's will, and if sensitivity is raised to the maximum, Kiva can discern the sound of a needle falling up to 3km away.
- Gau Crusher (ガウ・クラッシャー, Gau Kurasshā) - The silver mouth plate. It is actually a set of metal tusks crafted out of sharpened Lucifer Metal (ルシファーメタル, Rushifā Metaru). It has a jaw force of 1.2t and can chew through a metal ball that is about 8cm in diameter. An air purifier is installed inside to decompose and purify toxins. It also takes in and purifies all substances necessary for breathing from the surrounding air; this function even works within a vacuum state.
- Darkness Choker (ダークネス・チョーカー, Dākunesu Chōkā) - The black choker device on the base of the neck area. Among monsters, a necklace that imitates a demon's face is a favorite decoration of those with power. Among lower monsters, it is said that they simply look at this ornament, meaning that it serves no real functional purpose and is just for decorative purposes.
- Bloody Lung (ブラッディラング, Buraddi Rangu) - The red chest segment. It is where Kiva's power is stored. its red coloring is due to the fact that this is where the most demonic power is accumulated. It sends power to the whole body via its black blood vessels that have been branched in layers.
- King Singlet (キングシングレット, Kingu Shinguretto) - The chest armor. It is a strong auxiliary armor that protects Kiva's body, and at the same time functions as a restraint to suppress potential explosion of demonic power. It is made out of Lucifer Metal and has been coated in Trysilvania Silver to further suppress demonic power.
- Ptera Plate (Shoulders) (プテラ・プレート (肩), Putera Purēto (Kata)) - The shoulder armor. They are restraints that suppress Kiva's power amplification. Kiva's power, which has been activated by Kivat and amplified by the Demon Emperor Stone, is immeasurable and could potentially cause Kiva to self-destruct. Hence the need for restraints.
- Catena (カテナ, Katena) - Chains wrapped around the shoulders and the right leg. It is crafted out of Lucifer Metal and is coated with Trysilvania Silver. Furthermore, a seal has been engraved on its surface to prevent an explosion from demonic power overload. (Note: 'Catena' is Italian for 'chain'.)
- Doran Mail (ドランメイル, Doran Meiru) - Kiva's bodysuit. It is a tough inner suit made from the leather of the Black Dragon Gaora Doran (ガオーラ・ドラン, Gaōra Doran), and has been processed by using the same dragon's fangs. It protects the wearer from extreme weather conditions, whether it be burning hot or freezing cold. It is extremely difficult to pierce with currently existing bullets and knives.
- King's Breath (キングブレス, Kingu Buresu) - Demonic power amplification bracelets located on the wrists. Red Demon Emperor Stones are embedded. The power of the stones amplifies Kiva's power several times giving Kiva superhuman strength. It has been coated with Trysilvania Silver for easier control.
- Blood Vessel (ブラッドベッセル, Buraddo Besseru) - An energy flow path used to distribute Kiva's power across the whole body. By using Kivat's body as the 'core', it has the function of efficiently circulating the power of the demon throughout the whole body.
- Sylvania Knee Guards (シルバニア・ニーガード, Shirubania nī Gādo) - The kneecaps. Not only do they protect Kiva's knees, but they also serve as a resistor to control the demonic power flowing into the feet.
- Hell's Gate (ヘルズゲート, Heruzu Gēto) - The metal right leg restrainer. It is forged out of Trysilvania (トライシルバニア, Toraishirubania). This restraint, dubbed the Gates of Hell (地獄の門, Jigoku no Mon), opens up when Kiva utilizes the Wake Up Fuestle, allowing the Catena chains to open up, fully opening Hell's Gate. When opened, it resembles bat wings, and serve to ensure that kicks from a high altitude land on targets. Its tip is made of Lucifer Metal and is as sharp as a diamond. Its insides have been dyed crimson due to the influence of the Demon Emperor Stones. It also plays the role of power release plates, diffusing and emitting any power that rebounds during impact.
- Demon's Mount (デモンズ・マウント, Demonzu Maunto) - The red parts encasing the right leg. They are fixtures that hold the demon stones in place while keeping the right leg from exploding. Originally, it had a silver coloration due to it being crafted out of Trysilvania, but has been dyed red due to the influence and power of the stones. it has been designed to invoke the face of the legendary Demon King's face, which has been handed down between monsters.
- Goldie Vessel (ゴルディ・ベッセル, Gorudi Besseru) - A golden Blood Vessel that flows demonic power through the Demon Emperor Stones of the air, sea, and land via bottleneck effect.
- Demon Emperor Stone of the Air (Blue Stone) (宙の魔皇石(碧石), Sora no Ma Ō Seki (Ao Seki)) - The top stone located on the upper right leg. It amplifies demonic power with the power of the cosmic spirit (宇宙の精霊, uchū no seirei). After passing through the Blood Vessel, the first area where demonic power is accumulated, demonic power is sent through the Demon Emperor Stones. From there onwards, power is amplified twice more than usual, allowing Kiva to utilize great power.
- Demon Emperor Stone of the Water (Blue Stone) (水の魔皇石(碧石), Mizu no Ma Ō Seki (Ao Seki)) - The middle stone located on the lower right leg. It receives demonic power from the Demon Emperor Stone of the Air and further amplifies it. It is said that the water spirit (水の精霊, mizu no seirei) resides in here, and with its power, the demonic energy is twice amplified. At this point, demonic energy has been amplified four times.
- Demon Emperor Stone of the Land (Blue Stone) (地の魔皇石(碧石), Chi no Ma Ō Seki (Ao Seki)) - The lowest stone located on the right foot. With the help of the land spirit (地の精霊, ji no seirei), amplified energy is amplified to the maximum. The reason for dividing the amplification process into three stages is a precaution against the possible destruction of Kiva during the process. At this point, demonic energy has been amplified by a factor of eight, giving Kiva enough energy to execute the Darkness Moon Break.
- Devil's Mouth (魔斬口, Mazankō) - The right foot. A red Demon Emperor Stone is fitted on the sole, where demonic energy flows out of during the Darkness Moon Break. By releasing energy amplified by all three Demon Emperor Stones at once, tremendous destructive power is unleashed.
- Balancer Anklets (バランサー・アンクレット, Baransā Ankuretto) - The ankle armor. The right leg's Balancer Anklet is hidden within Hell's Gate. The power contained within is far greater than ordinary people. While keeping the power balance with the right leg evenly, it can deliver an explosive destructive power of about 8 tons even with a regular kick in a restrained state.
Kamen Rider Kiva has the following finishers:
- Darkness Moon Break (ダークネスムーンブレイク, Dākunesu Mūn Bureiku) - By having Kivat blow the Wake Up Fuestle, the Catena chains binding the Hell's Gate (ヘルズゲート, Heruzu Gēto) on Kiva's right leg break open. Kiva then performs a powerful kick with an impact of 30,000 kg, enough to leave a crater in the shape of a bat's wings (Kiva's insignia) on any surface upon contact; the glass body of a Fangire shatters almost instantly. Kiva can also perform a stronger variation of the Darkness Moon Break when engulfed in Castle Doran's fire. When the Darkness Moon Break is performed, day turns into night and a crescent moon appears in the sky.

- Doran Mail (ドランメイル, Doran Meiru) - The undersuit that holds the power of Kiva Emperor Form is the same Doran Mail as Kiva Kiva Form, but in response to the final awakening, the blood vessel patterns fluctuate and changes into a pattern that is convenient for the flow of the amplified Demon Power.
- Goldie Shoulder (ゴルディショルダー, Gorudi Shorudā) - The shoulder armor made of Lucifer's Metal, the shoulder pad has a sharp tip and has a hardness that is strong enough to cause fatal injury to the opponent just by ramming them.

DoGaBaKi Emperor Form (ドガバキエンペラーフォーム, Dogabaki Enperā Fōmu) is Kiva's extra final form accessed by using Tatsulot while in DoGaBaKi Form. In this form, Kiva has access to all three Arms Monster weapons.
This form has the following finisher, accessed by pulling Tatsulot's Imperial Slot (インペリアルスロット, Inperiaru Surotto):
- DoGaBaKi Emperor Break (ドガバキエンペラーレイク, Dogabaki Enperā Bureiku) - An enhanced version of the Emperor Moon Break, augmented with the power of the three Arms Monsters.
In the Hyper Battle Video where this form debuts, Wataru is not the one to assume this form, rather it is assumed by the viewer (a young boy) who transforms into Kiva.This form is exclusive to Kamen Rider Kiva: You Can Also be Kiva.
- Punching Power: 10 t.
- Kicking Power: 18 t.
- Maximum Jump Height: ∞ m (Able to fly)
- Maximum Flight Speed: Mach 3.4
Resulting from infusing his own desire into the Bloody Rose, Wataru's Fangire nature is triggered as Kiva transforms from Emperor Form into Flight Style (飛翔態, Hishōtai), alternatively called Flight Mode or the Emperor Bat (エンペラーバット, Enperā Batto), a dragon-like form similar to a Six Pillars Sabbath.
In Kamen Rider Kiva: King of the Castle in the Demon World, Arc uses his Legendorga baptism to force Wataru to assume this form in an attempt to kill his father, Otoya Kurenai, though his father managed to bring him back. Wataru later re-accesses Flight Style to defeat the giant Rider. The Legendorga version of Flight Style has a darker color scheme as its golden accent turns brown and the red on his wing becomes maroon.
Flight Style has the following parts:
- Hell's Crown (ヘルズクラウン, Heruzu Kuraun) - The red armor on the head. The Demon's Plate moved from the Emperor Form's chest to Flight Style's head, holding the three Demon Emperor Stones: Air, Water, and Earth. By having three giant Demon Emperor Stones on its head that amplify and release the mighty emperor's power, it is directly connected to the brain and contributes to bringing out the full power of Wataru to the utmost.
- Bat Scope (バットスコープ, Batto Sukōpu) - The eyes. It has a super-vision that allows Kiva to see ants on the ground from 2000m in the air. It has a wide field of view of 160 degrees forward and works well in intense aerial combat.
- Big Jaw (ビッグジョー, Biggu Jō) - The jaws. It has sharp fangs that can bite through a 300mm diameter steel rod without resistance. In addition to emitting ultrasonic waves from the oral cavity, it is possible to determine Kiva's position and also to emit a flame generated from the power of the devil called Hell's Flame (ヘルズフレイム, Heruzu Fureimu).
- Goldie Heart (ゴルディハート, Gorudi Hāto) - The heart The cardiopulmonary is super-enhanced by the transformation into Flight Style enables Kiva to perform similarly as in the atmosphere in space.
- Lucifer's Claw (leg) (ルシファークロー (脚), Rushifā Kurō (Ashi)) - The legs that can lift anything that weighs more than Kiva's own weight up to 50 tons. The sharp claws on its toes have the power to instantly tear the enemy into shreds.
- Imperial Tail (インペリアルテール, Inperiaru Tēru) - The tail. It acts as a rudder during high-speed flight, but it also has strong hitting power and can reflect attacks or use its tail to make strong hits.
- Goldie Arm (ゴルディアーム, Gorudi Āmu) - The arms that form the frame of the Bloody Wing. The strength of Emperor Form's armor is inherited as it is, and it is a strong armor that cannot be hurt by normal weapons.
- Sonic Claws (Wing) (ソニッククロー (翼), Sonikku Kurō (Tsubasa)) - Huge claws on the wingtips that can divide even large passenger planes using only shock waves generated when shaken. It is made of polished Lucifer Metal, and it is possible to use the claws on both sides to strike out and perform the Demon Pliers (デモンプライヤー, Demon Puraiyā) attack.
- Flying Demon Emperor Stone (飛空魔皇石, Hi Sora Ma Ō Seki) - It is a Demon Emperor Stone that is an auxiliary buoyancy device that stabilizes the flight of Flight Style and soar to ultra-high altitudes.
- Bloody Wing (ブラッディウイング, Buraddi Uingu) - The cloak of Emperor Form is altered to become the wings. It enables ultra-high-speed flight at Mach 3.4, and can instantly generate strong gusts of wind with a range of 40m by flapping while hovering.
- Doran Mail (ドランメイル, Doran Meiru) - The undersuit of Kiva's armor is transformed to wrap the altered body, resulting in a tough black armor. The performance is almost the same as that of Emperor Form.
Flight Style has the following finisher:
- Bloody Strike (ブラッディストライク, Buraddi Sutoraiku) - Kiva Flight Style unleashes a blast of energy from his mouth, amplified by the Demon Emperor Stone on the forehead.
- "Final Form Ride: K-K-Kiva!"
- ―Transformation announcement[src]
Kamen Rider Decade's Final Form Ride allows Kiva to change into the Kiva Arrow (キバアロー, Kiba Arō). Once the Final Attack Ride Card is in, the bow can be pulled back, getting the Hell's Gate to open up for the Decade Fang attack.
A manifestation of him was summoned and used by Diend to perform Diend Fang attack back in the World of Faiz.Appearances: Decade Episode 11, All Riders vs. Dai-Shocker.
- Main article: Bloody Rose
A unique violin, the Bloody Rose (ブラッディ・ローズ, Buraddi Rōzu) was created by Otoya and Maya as the "ultimate violin", later rumored to be a product of Otoya selling his soul to the devil himself, which is not entirely false, in a sense. The Bloody Rose only sounds whenever a violent Fangire is detected in the area, its music only heard by Kivat and Wataru, who hears it as a voice commanding him to "Fight", as it pinpoints the exact location the Fangire could be found. When played, the Bloody Rose can also disrupt a Fangire's activity. However, the Bloody Rose is sympathetic to Wataru's mentality as it cracked when he fell into a deep depression. However, after repairing it, Wataru learns the Bloody Rose holds the desires of his father, placing in it his own desire which allowed him to assume Flight Style.

An unintentional possession of Wataru by Momotaros. U-Ryotaro and Kazuya locate the base of the Evil Organization after Wataru tips them off.
- Otoya Kurenai: Wataru's father and a person he looked up, Wataru was told by his mother that Otoya was a great man. When Wataru learned of Otoya's troublesome actions though, he became saddened at what his father had done. While saddened, Wataru still continued to love Otoya as his father. However, meeting the Frog Fangire later convinced Wataru that Otoya did have some good inside, regaining the respect he had previously lost. When meeting with Otoya, his father said that he should continue living on with his life. Witnessing Otoya sacrifice himself to stop the Bat Fangire had also left a profound effect on Wataru, giving him the strength to become a true Kamen Rider. In the final battle against the revived Bat Fangire, Otoya appeared in spirit to help Wataru, saving him from falling to his doom. Telling Wataru that he will always be there when needed, Otoya's words motivated Wataru to continue on.
- Maya: Wataru's mother. Wataru questioned her disappearance for years because she left him when he was still a child. Maya dearly loved Wataru as her son, and wished they would reunite. When they had finally reunited though, there were clear tensions between mother and son. Despite this, when Wataru had lost confidence in himself due to Bishop's actions, it was Maya that healed her son's emotional pain. Appearing in his dream, Maya told Wataru that he should forgive himself for what had happened, expressing her faith in him. By the time of the final battle, it is clear that Wataru and Maya have restored their relationship as mother and son.
- Taiga Nobori: Wataru's half-brother. Initially regarding Wataru as his best friend, Taiga greatly cared for him, despite having a strong hatred towards humans. Wataru also cherished his friendship with Taiga, though was shocked that he was engaged with Mio. While he cared for Wataru as a friend, Taiga also somewhat looked down on him, even referring to him as a low-class human being to Mio at one point. This may have partially been from the jealousy he felt. Nevertheless, Taiga adamantly chose not to kill Wataru when suggested to do so by Bishop. Once both had learned of each other's identity as Kamen Rider Kiva and Saga, Taiga deduces that Wataru is his half-brother, much to his joy. Telling Wataru that he had always felt alone, Taiga tried to convince him to join the Fangire's cause to enslave humanity. Wataru's refusal to do so, as well as the rivalry they had over Mio's affections, drove a wedge between the two. Things came to a head when Mio had died. Believing Wataru to have killed Mio, Taiga became bent on murdering his brother. Upon being defeated and stripped of his title as the King of Fangires, Taiga was consumed with jealousy. Challenging his brother to one final battle as Kamen Rider Dark Kiva, the two were ambushed by Bishop and his revived Fangire army. Defeating the army together, Wataru embraced Taiga and told him that he was not alone. Confused, Taiga questioned his true motive. Shima then appeared and told Taiga that Wataru was trying to protect him. The two brothers reconciling, they faced the revived Bat Fangire together. After defeating the Bat Fangire, Wataru and Taiga resumed the fight for the title as the King of Fangires, though without animosity. Later, Taiga proposed to his company of a new energy source to nourish the twelve Demon Races, showing that he has adopted Wataru's mindset about humans. Regardless of who the victor was in the final battle, Taiga will always be there for his little brother.
- Kivat-Bat the 3rd: Wataru's personal bodyguard, Kivat encourages Wataru to do what is right as Kamen Rider Kiva. Wataru is very close with Kivat, often talking with him on various subjects.
- Masao Kurenai: Wataru's son from the future, who became Kamen Rider Kiva. Masao seems to be fond of his father, calling him "papa" and asking for his help to deal with the Neo-Fangire.
- Castle Doran Residence
- Jiro: Promising Otoya to help Wataru in his time of need, Jiro solemnly upholds his vow, to the point of directly assisting Wataru when necessary. Acting almost like a godfather to him. When Wataru tried to deny the fact that he learned Mio and Taiga's identity as the Pearlshell Fangire and Kamen Rider Saga, Jiro slapped him out of his dilemma and sternly told him to not avert his eyes from reality. When Wataru became suicidal from Mio's death, Jiro was the one who saved him from Taiga's wrath, as well as being the one that sent him into the past to meet his father. Much later, when Wataru proclaimed that he would become the new King of Fangires, Jiro was shocked and initially tried to dissuade him from doing so. When Wataru fiercely showed his determination though, Jiro complied, bowing down towards him as a servant.
- Ramon: Before meeting Wataru personally, Ramon seemed to be rather aloof towards Otoya's son. At one point, he had even suggested to the other Arm Monsters that they eat Wataru to be released from service. When the two had met each other however, Ramon began affectionately referring to Wataru as "Onii-chan" and decided to help him. Alongside Jiro and Riki, Ramon became Wataru's servant when he proclaimed himself as the new King of Fangires, showing that he genuinely respects Wataru's power.
- Riki: Unlike Jiro, Riki does not seem to be particularly concerned with Wataru in general, even agreeing with Ramon's proposal to eat him. Since Jiro will not allow such an act though, Riki continues to assist him. Notably though, when Wataru proclaimed himself the new King of Fangires, Riki became an obedient servant, showing that he has come to respect Otoya's son.
- Tatsulot: Wataru's second personal bodyguard, Tatsulot acts as his supporter in a manner similar to Kivat-Bat the 3rd,
- Shizuka Nomura: Wataru's good friend, Shizuka is revealed to be slightly attracted towards him. Despite Wataru being perceived as odd by others, Shizuka knows the good he has inside and will support him in his time of need.
- Keisuke Nago: When they first met, Wataru thought of Nago as a sort of mentor, while Nago saw Wataru as somewhat weak and indecisive, but ultimately a kindhearted figure. Since he did not know of Wataru's identity as Kamen Rider Kiva, Nago would constantly attack him as Kamen Rider Ixa, to Wataru's chagrin. Upon going to the past and meeting with Otoya though, Nago had become kinder and showed more respect towards Wataru. Once he learned of Wataru's alter-ego, Nago accepted him as a fellow warrior and encouraged him to fight alongside the Wonderful Blue Sky Organization. Even when learning of Wataru's half Fangire nature, Nago continued to trust him and acted as a friend.
- Megumi Aso: Wataru's ally. Megumi saw him as a strange and meek boy who needed to become more socially adept. While generally nice to him, Megumi could be somewhat condescending towards Wataru, mistakenly thinking of him as weak. Initially seeing Kamen Rider Kiva as an enemy, Megumi attacked him on a number of occasions. After being saved by Wataru as Kiva though, Megumi decided that he is an ally. When Wataru revealed his identity as Kamen Rider Kiva, Megumi initially did not take it seriously, before Nago confirmed it himself. This caused Megumi to see Wataru in a different light, though still caring for him as her friend. Even when Shima ordered for Wataru's termination, Megumi knew she could not do such a thing. Much like Nago and later Kengo, Megumi believes in Wataru regardless of his heritage and knows he will do what is right.
- Kengo Eritate: Kengo admires Wataru's musical skills and acknowledges him as the kindest person he knows. When Kengo lost his ability to play the guitar though, Wataru could not bring himself to tell Kengo the bad news. This, however, caused Kengo to feel anger at Wataru upon learning the truth. Losing the respect he had for Wataru, Kengo broke off their friendship. Even when learning of Wataru's identity as Kamen Rider Kiva, Kengo continued to feel hatred towards him and tried to kill him with the Ixa system. When Wataru saved him from Bishop though, Kengo felt regret at what he had done. Wholeheartedly apologizing to Wataru for his previous actions, Kengo admitted that he had only used Wataru as a scapegoat to not face his own weakness as a person. The two eventually mended their friendship.
- Mio Suzuki: Wataru was attracted to Mio and wanted to have an intimate relationship with her. The feeling was mutual. Due to her status as the Queen of Fangire though, the two could not form such a relationship. Worse, their relationship had soured Wataru's relationship with Taiga. When Mio had died from being struck by Wataru's Rider Kick, Wataru was filled with guilt. Yuri and Otoya convinced him though, that Mio would have wanted Wataru to live his life, with Mio appearing in spirit to confirm this before dissipating. It is unknown if Wataru ever learned the truth about Mio's death, though it is likely that Taiga told him later on.
- Mamoru Shima: While Shima initially did not see anything noteworthy of Wataru, things changed when he revealed his identity as Kamen Rider Kiva. Shima then saw Wataru as an enemy. Seeing him as an even greater threat than the entire Fangire race, Shima would attempt to form a temporary alliance with Taiga to destroy Kamen Rider Kiva. The love that Nago, Megumi, and Kengo had for Wataru as their dear friend changed Shima's mind though. Shima eventually decided that Wataru could help the Wonderful Blue Sky Organization. When Taiga made it so that Shima would become a Fangire, the latter came to recognize how poorly he treated Wataru and apologized. When Taiga had murdered Shima, Wataru was overcome with anger. When Shima later reappeared alive and well, he told Wataru what had really happened and asked that he protect Taiga. Wataru complied and did what he thought as necessary. When Taiga questioned Wataru's motives, Shima explained Wataru's intention, helping the two brothers reconcile.
Behind the Scenes
Wataru Kurenai is portayed by Koji Seto (瀬戸 康史, Seto Kōji), who reprised his role in Kamen Rider Decade for the first and last episodes as well as in Kamen Rider × Kamen Rider W & Decade: Movie War 2010. As a child, he was portrayed by Yohei Itagaki (板垣 陽平, Itagaki Yōhei).
As the leading Rider protagonist of Kamen Rider Kiva, Wataru Kurenai (Kamen Rider Kiva) is labeled Kamen Rider #24 (仮面ライダー24号, Kamen Raidā Nijūyongō) and Heisei Rider #9 (平成ライダー9号, Heisei Raidā Kyūgō). [Quiz! Decade Countdown!!]
His name translates to "Crimson Overgo".
- Since Wataru is confirmed to be younger than Megumi Yuri (born in December 29 of 1987), Maya would mathematically have been pregnant with him for a minimum of 12 months, as Otoya's death occurred at the beginning of 1987..
- Despite Kiva's base form having the slowest running speed in comparison to past primary Heisei Riders, Wataru is ironically always running towards his foes, as well as using acrobatics in combat.
- Wataru is the the first Primary Rider who is explicitly shown to have one parent who is still alive. Other Primary Riders often have their parents dead or never explicitly mentioned of their whereabouts.
