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. Befitting of an Executive, he has no qualms eliminating the Port Mafia's enemies by any means necessary, including murder, however, isn't nearly as homicidal in his tactics.
