"I've got it together. Roidmude!"
―Genpachiro regains his memory.[src]

"You're dead wrong if you think nothing's changed. Its only natural to be a little scared but I've got your back. So does the little lady, Kyutaro, doctor and the captain. So you don't have to put a front, man. Just be yourself."
―Genpachiro's advise to Shinnosuke.[src]

"The heavens call... The earth cries out... The crowds roar... Hey, what with this script! Off you go! I am the detective of justice, Kamen Rider Genpachiro!"
―Genpachiro parodying Shigeru Jo's pre-battle catchphrase[src]

Genpachiro Otta (追田 現八郎, Otta Genpachirō) is a police officer liaison with the Special Investigation Unit.

History[]

Background[]

Genpachiro Otta was a veteran policeman who operated alongside his mentor, Shingo Tachibana. Five years ago, a vigilante named Judge attacked random people. While the two tried to track him down, Judge took his own life after seemingly revealing his identity as Toma Okajima. However, Otta and Tachibana had didn't buy for the trick and continued searching for more clues but to no avail. In the end, Tachibana retired two years later but continued to track on the case.

Otta continued his work as a policeman and successfully ranked up to the Lieutenant rank. He had also been acquainted with Shinnosuke Tomari when he was previously at the First Divison.

Informant To Special Cases[]

Lt. Otta was eventually assigned to work with the Special Investigation Unit as a liaison, much to his hesitance. During his first assignment to the team, Otta tried to fit himself despite believing the whole team to be a nuisance. He has a sharp tongue, but he is a competent detective whose methods surprisingly match Shinnosuke's. In reality, there is an childish side to him and it's the one thing he doesn't want anyone to know.

In the beginning, he stubbornly denied the existence of the mechanical lifeforms and Kamen Rider. However, Lt. Otta would catch glimpses of Roidmudes and Kamen Rider Drive, leading him to fully trust the team and tried to get the higher police forces to cooperate with the Unit. However, his efforts eventually in vain as they never believed in him, thinking that he had became more childish. Nonetheless, he tried his best to apprehend the Roidmudes with his work eased from the help of Rinna's backpack.

Sometime later, Judge began to resurface and incapacitated a group of criminals. Hearing the case again, Otta took it on his own and threatens to quit as a policeman if he fails. Shinnosuke accompanied him and discovered the vigilante appeared in the form of the Judge Roidmude. Otta soon pieces together that his mentor, Shingo Tachibana, has been colluding with the Judge Roidmude to lure in the real Judge. While he expressed despair, Otta befriended Shift Deco Traveller, who cheered him up. Otta manages to arrest the real Judge and as Tachibana prepares to surrender for his crimes, Otta forgives him as his mentor's only crime was giving in to his torment that has already been dealt with.

Otta and Kyu screaming

Otta and Kyu find out Drive's secret identity.

During the plight of the Sword Roidmude, Otta and Kyu would finally learn Shinnosuke Tomari was Kamen Rider Drive after seeing him transform to save Akira Hayase. After the fight ended, they also learn Kiriko's brother Go being Kamen Rider Mach. Otta and Kyu were brought to the Drive Pit for the first time where the Special Investigation Unit are now officially part of the Kamen Riders' activities.

Unbeknownst to Otta, he had been victim to Roidmude 001's memory manipulation ability as part of his attempt to distract the police force from being aware of the Roidmudes, thus explaining why Otta kept mispronouncing "Roidmude" despite other's trying to correct him. After taking a dose of Rinna's cure, he was able to enunciate "Roidmude" properly. Thanks to his position as Lieutenant and his close position with the Kamen Riders, Otta would continue to assist Shinnosuke and Kiriko in Roidmude related incidents and arresting any human involved in connected crimes.

Eventually, the Special Investigation Unit have accomplished their mission of shutting down the 108 Roidmudes and ending Tenjuro Banno's reign of terror. With their mission complete, Krim locked himself and all Core Driviar equipment beneath the wrecked Drive Pit. Otta said his goodbyes to his dear friend Shift Deco Traveller one last time as Mr. Belt prepares the lockdown and all of the Unit members saluted for him. Following this, Otta was promoted to inspector and later became the new chief of the First Division.

Other Events[]

Kamen Rider × Kamen Rider Drive & Gaim: Movie War Full Throttle[]

The entire Special Investigations Unit become involved with the "Ultimate Lupin" case concerning the thief being actually a Roidmude. When Lt. Otta manages to follow Lupin in a getaway truck, he attempts to apprehend him only to be knocked away from the moving road and saved by Drive in the nick of time. While Shinnosuke proceeded to investigate the case, he discovers that there is a mole amoungst the Special Investigations Unit. After gathering Kiriko, Rinna, Sanjo, Lt. Otta, and Chief Honganji, Shinnosuke exposed Kiriko to be Lupin undercover.

Otta in the altered timeline as a Shocker lieutenant

In the altered timeline created by Shocker's History Modifying Machine, Otta is altered as a lieutenant of Shocker and had been remodeled as one of their cyborg monsters, Cheetahkatatsumuri. After Shinnosuke Tomari regains his sense of self, he murdered Jun Honganji and threw Kiriko Shijima off the building.

During the Kamen Riders' final battle against Shocker, Cheetahkatatsumuri immobilizes Deadheat Mach with his slime, allowing an opening for several Shocker monsters to bombard Mach, resulting in Go's death. However, Cheetahkatatsumuri is soon after confronted by Kamen Riders 1, 2, and 3 and is destroyed by their combined Rider Triple Kick. His alternate life in the world was unwritten when the destruction of the History Modifying Machine restores the timeline, returning Otta to his proper place in history.

Kamen Rider Drive: Surprise Future[]

When Kamen Rider Drive was engaging in a battle against a Giant Roidmude, he apparently fled the scene after the Trailer-Hou malfunctioned. This forced the Metropolitan Police Department to issue a nationwide manhunt for Shinnosuke, while the rest of the Special Investigations Unit were pleading his innocence. Kiriko and Lt. Otta would later arrive to the battlefield where the Kamen Riders fought Dark Drive and the Future Roidmudes. They would witness Shinnosuke destroying Mr. Belt and Roidmude 108 revealing his true colors.

Despite reporting this news to the Metropolitan Police deputy officer, Shinji Koba, it still couldn't convince him to lift the search for Shinnosuke. Upon discovering that the entire events have been orchestrated by Roidmude 108, the Special Investigations Unit convince the Metropolitan Police to assist Kamen Rider Drive to prevent the Eternal Global Freeze.

Drive Saga: Kamen Rider Chaser[]

Sometime after the defeat of the Paradox Roidmude, the Special Investigations Unit began to deal with a Roidmude case involving the human guise of Roidmude 051. While Shinnosuke and Go as they dealt with their Roidmude case suspect lying in the border between Tokyo and Futo, Lt. Otta manages to apprehend the suspect, much to the two's surprise as it turned out their suspect had been a Roidmude the entire time.

Kamen Rider Drive: Final Stage[]

In the stageshow, Otta became the second user of the Mass Produced Mach Driver, transforming into a Production Model Mach, which he called himself "Kamen Rider Genpachiro" (仮面ライダー現八郎, Kamen Raidā Genpachirō).

Kamen Rider × Kamen Rider Ghost & Drive: Super Movie Wars Genesis[]

Three months after Krim sealed the Drive technology in the Drive Pit, Otta would reunite with most of the Special Investigations Unit in the Daitenku Temple as Shinnosuke is stranded in 2005 with Takeru Tenkuji. He would work alongside old friends and new allies regarding the butterfly effect that is affecting their timeline. When the Kamen Riders reunited to the present to battle Da Vinci Gamma's army, Otta accompanied everyone else to battle against the army of Gamma Assaults.

After the battle ended, Otta attended the wedding of Shinnosuke and Kiriko along with the rest of the former Special Investigation Unit as well as the Mysterious Phenomenon Institute team.

Kamen Rider Drive Saga 2[]

"Heart is a... Kamen Rider?"
―Otta, surprised that Heart became a Kamen Rider[src]

Two years after defeating the Roidmudes, Lt. Otta and Rinna are in a relationship together and became engaged, with him giving her a ring costing at least three months of his salary. He ends up working alongside with the revived Heart as they pursue a serial case involving the human templates of previous Roidmudes being attacked. As the both of them pursued the case, they both learned the culprit of the case is none other than Roidmude 5886. Otta initially had an uneasy alliance with the Heart due to his past actions and kept a control remote to keep him in check. Despite their apprehensive start, Otta was present to witness Heart's transformation into Kamen Rider Heart and cheered for him on as he defeated 5886, but ends up using all of his power. Heart and Otta share a few last words, glad to have formed a strange but unique friendship. Although Otta's job and Rinna's nagging briefly put a pause in their engagement, they both eventually made amends and intend to marry one day.

Kamen Rider Revice: The Mystery[]

In 2022, Genpachiro Otta, as the captain of the First Division, infiltrated the Pension Nijitenka to investigate the reported presence of a Roidmude. He was soon joined by Fenix commander Hiromi Kadota and Ikki Igarashi who were chasing after mysterious Vistamps.

Kamen Rider Juuga VS Kamen Rider Orteca[]

It is revealed that Genpachiro continued to keep in contact with Hiromi, as the latter would occasionally seek advice from him. However, Rinna mistook "Hiromi" to be a girl her husband was cheating on her with after looking at their conversations through text, and moved her belongings into her own lab after an argument with him.

After Hiromi was brought into Rinna's lab to tell her the truth, Rinna was quick to forgive her husband. When Genpachiro later went to arrest Orteca after the latter lost in the duel against George Karizaki, Rinna went up to her husband to apologize, and the couple happily amended their relationship.

Personality[]

After his first assignment to the Special Investigation Unit, he finds the team a burden and mocks them by calling it an "Occult Club". Even if that's the case, he gets along with Shinnosuke and loves children something which he didn't want anybody to be aware of. Due to this, he always shown partnering with Shinnosuke in most of his missions.

Like must higher-up police officers, at first he believes in anything he can see. Unfortunately for him and to the annoyance of everyone, this doesn't include the Heavy Acceleration effects, even when he is experiencing one, to the point of blatant denial. He eventually grows out of this, starting with the Crash Roidmude incident, as well as seeing glimpses of the Kamen Rider, then reaches the point where he believes that a Roidmude was the culprit of a land shark getting assaulted in his house.

Even if he has a lot of comic relief scenes, but he is also at times helpful and observant of one's problems.

Notes[]

Gen Drive depict

Gen's initial depiction of Drive.

Gen's four Riders

Gen's updated sketches.

  • Genpachiro's glimpses of Kamen Rider Drive's forms (Type Speed's gauntlets, Type Wild's legs, and Type Technic's Technica Met helmet) coincide with the general color scheme of Kamen Rider 2.
    • Witnessing Kamen Rider Mach in full, Gen is initially confused, mistaking him for Drive. He gets a better idea of the Kamen Riders when he comes face to face with Drive, observing his full body in Type Speed. Thus, he sketches what he believed to be four different Kamen Riders: Drive, Mach, and two unnamed Riders colored black (Drive Type Wild) and green (Drive Type Technic), not realizing they are merely alternate forms of Drive. As he hasn't seen Wild or Technic in full, Gen is forced to improvise, resulting in inaccurate drawings (e.g., 'black's' tire is on his chest as opposed to Type Wild's right shoulder, and 'green's' is across his waist as opposed to Type Technic's upper chest).
      • Also notable is his mistaking of Drive's use of Tire Exchange, as a note written on the picture of Drive points out 'tire splitting' despite the tire being the one for Type Speed.
    • It is very interesting that a Shift Car named Shift Speed Wild Technic make an appearance as a movie viewer-exclusive toy to represent this "form".
  • Stemming from 001's memory manipulation ability, Genpachiro had a running gag of being unable to pronounce "Roidmude" correctly, constantly calling them "Loli Shōjo" (ロリ少女 kanji lit. "Young Girl;), "Moe Nude" (モエニュード), "Hui Guo Rou" (ホイゴーロー, Huí Guō Ròu, lit. twice cooked pork in Chinese) "Koinyobo" (恋女房 lit. "Loving wive") and "Roi mouchou" (ロイモーチョー)
    • After getting a dose of Rinna's cure, he can now pronounce "Roidmude" successfully.
  • Ever since his encounter with the Deco Traveler Shift Car, the SFX of Deco Traveler has been accompanied with him.
  • Strangely, despite claiming to distrust Roidmudes in general[1], Genpachiro has previously shown no problems with Chase's presence, at one point even trying to tell him what romantic love is.
    • This may simply be due to Chase's unique origins, being a creation of Krim Steinbelt that identifies himself as a Kamen Rider.
