"Officer Tomari, someone like you so loved by coworkers, could never understand! This is human nature. Every single one has a monster lurking within their hearts!"
―Nira revealed his true facade.[src]

"Adios, Kamen Rider."
―Nira's word before he fires the bullet to Shinnosuke.[src]

Mitsuhide Nira (仁良 光秀, Nira Mitsuhide) was a corrupt manager of the First Investigation Division of the Tokyo Metropolitan Police Department. He worked under Soichi Makage, another corrupt secretary of the National Bureau of Defense.

With the help of Roidmude 106, later Brain, he synchronized with them to become Thief Roidmude (シーフロイミュード, Shīfu Roimyūdo).


Murdering Eisuke Tomari

Nira kills Eisuke.

Formerly acquainted with Eisuke Tomari, Nira envied him for his success in apprehending criminals. One day in the year 2003, Nira intruded a bank where several people had been held hostages by Itsuro Negishi and Maruya. When Negishi pointed his gun to Eisuke after he tried to cover a little girl, Nira took this opportunity to paralyse Maruya and confiscated his gun but instead of targeting Negishi, he was blinded by jealousy and instead choose to fire Eisuke. Traumatized of what he had done, Roidmude 001/Soichi Makage revealed himself and erased what happened in the robbery, thus making a pact. Who Claimed the Life of Eisuke Tomari?

Working against Shinnosuke Tomari

In 2014, he was promoted to the new manager of First Investigation Division and sometime later, he also became a member of the National Bureau of Defense. After the Roidmude cases surfaced, 001 ordered him to purposely give the Special Investigation Unit trouble and spite Shinnosuke when possible.

The truth is revealed.

When Freeze abandons Nira, Nira aids the Special Investigation Unit out of spite, What is Waiting At the End of Evolution? and even helps to aid Shinnosuke's revival Who Claimed the Life of Shinnosuke Tomari?. However, with Freeze stating that he was never the real murderer of Eisuke Tomari to Shinnosuke as his final words, Nira realised that the truth would be surfaced sooner. To prevent this, Brain helped him by fusing him to Roidmude 106, becoming Thief Roidmude and tried to steal every records and evidence that related to Eisuke until Shinnosuke unmasked him and thus, he was forced to reveal the truth. He was escorted by Brain to safety, where Brain used the Neo Viral Core to absorb Nira's jealousy and empowered himself, thus achieving Over Evolved. Who Claimed the Life of Eisuke Tomari?

Nira/Thief, with Brain in synchronization targets Yukari Kasawara, one of the eyewitness of Eisuke's death until the Kamen Riders rescue her though they did successfully manage to poison her. Nira and Brain later framed Shinnosuke for trying to take the lead of the Roidmudes and with Special Investigation Unit being backing him up. Despite Shinnosuke escapes with the help from his friends, but Nira/Thief faces him instead and nearly gets himself killed by Drive and Chase, had Brain not using his Super Evolve form. Nira lures Shinnosuke into the Unit's office, and fakes a hostage crisis with him as a hostage, using this to kill Shinnosuke under the alibi of self-defense. Why Did the Siege Happen?

However, with the help of Chase, Go, Mr. Belt, the Shift Cars (more specifically Dimension Cab) and Banno (to cure Yukari's poison), Shinnosuke was able to escape from Nira and at the same time bring Nira's crimes to light once and for all. Nira was later arrested by Shinnosuke after Brain's body was destroyed. Where Will the Bullet Guide Justice?


Nira revealing his nature to Special Investigation Unit members.

In the past, during his time as Eisuke's partner, he is also a police officer dedicated to his job but Eisuke's fame eventually changed his view, wanting only to take advantage of anyone for his own benefit. This had further influence on his morality and pride as an officer by killing Eisuke during a robbery despite having the greatest chance of serving justice and by extent, rising to fame for saving the hostages.

He likes toying with other people's lives and acted as a school yard bully to the Special Investigation Unit whenever a Roidmude case reported, portraying a high level of narcissism and thus this traits were among the reasons Makage stationed him to overseer the Unit. He also only cares for his own benefit, allowing Shinnosuke to transform when his life is in "jeopardy" by Protozero and sided with the Unit after being dumped by Makage but returned to serve the Roidmudes once more when his secret is about to be discovered.

Brain also described him as "The worst human", the fact which is true as he didn't even repent after getting arrested, yelling that the fight is not over and hope for Shinnosuke and the rests to be destroyed.

Behind the Scenes


Mitsuhide Nira is portrayed by Kisuke Iida (飯田 基祐, Iida Kisuke).


Nira's first name, Mitsuhide (光秀) has the kanji "Hikari" ( lit. "light"). Alternatively, the kanji can also be read as "mitsu" (みつ), another way of pronouncing "3".

His name in general also comes from Akechi Mitsuhide, a famous general in the Sengoku period who rebelled against Oda Nobunaga. This is justified with Nira's deception against the Special Investigation Unit.
