Mitsuhide Nira

"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 revealing his true nature

Mitsuhide Nira (仁良 光秀 Nira Mitsuhide) is the secondary antagonist in Kamen Rider Drive. He is also the murderer of Eisuke Tomari, who was the late father of Tomari Shinnosuke, and the one who concealed the existence of Roidmude, preventing any chance of stopping the Global Freeze from ever happening.

He is portrayed by Kisuke Iida.

Overview
Nira was the former manager of the First Investigation Division of the Tokyo Metropolitan Police Department. He worked under Soichi Makage, the secretary of the National Bureau of Defense, who was the human identity of Freeze Roidmude.

Initially, he was a mere antagonist who was aggresive towards the idea of Kamen Rider Drive, thus making him a foe to the SIU until Freeze's demise, where Nira seemly became an ally to the team. However, it was later revealed that he was already an ally to the Roidmudes all along, as well as being the real murderer of Eisuke Tomari. Nira later worked together with Brain Roidmude to stop Shinnosuke from exposing his crime.
