On the surface, Chūya is a temperamental and rather arrogant, blunt man. He revels in fighting, happy to show off his combative ability, and taking great pride in his reputation as the mafia's strongest martial artist. Taunting remarks pair with his pride, as he isn't above ridiculing his opponents in the middle of a fight. Ruthless as he is, Chūya seldom takes people's lives for granted and knows the importance of compromise and rationality.
