Naomasa Tsukauchi to Toshinori Yagi in "Wild, Wild, Pussycats"

Naomasa Tsukauchi ( (つか) (うち) (なお) (まさ) Tsukauchi Naomasa?), also known as True Man, is a police detective in the Police Force.


Naomasa is a tall man with short, black hair and somewhat-rectangular black eyes.  

As a member of the police force, he is normally seen in his uniform, which consists of his signature tan overcoat and matching hat, underneath which he wears a black suit, a green tie at his neck with matching slacks and dress shoes. 


Detective Tsukauchi is an earnest, hardworking individual who has earned the right to be a close friend of All Might, enough so, that he was even entrusted with the truth about One For All and the former's true form.

He appears to have a close relationship with All Might, as he even leaked sensitive information to the hero just because he felt it was the right thing to do.
