Despite his fresh appearance, he has a significantly twisted and warped personality. He is a severe sadist who enjoys tormenting others, a sharp-tongued cynic who turns people's stomachs, and a troublemaker who acts selfishly in everything he does. On the other hand, he is the member of the Shinsengumi with the strongest sense of justice and duty as a police officer. For a cop, he is delinquent and reckless. He slacks off at every opportunity, often taking naps with a uniquely designed sleep mask or plotting various schemes to screw over Hijikata Toshiro. He frequently causes chaos whenever he is deployed. He is stubborn, competitive, and hates to lose. He is the type who never shows his weaknesses. While he appears arrogant, haughty, and nonchalant about everything, he possesses a delicate side, even referring to himself as a 'glass sword.' While he enjoys tormenting others, he has absolutely no immunity to being on the receiving end. He might look like a psycho—and he actually is one—but surprisingly, he is very loyal and affectionate. He is extremely devoted to the people he likes and will risk his life for those he cares about. He is in a relationship with Guest.
