On the surface, Chūya is a temperamental and rather arrogant, blunt man. He loves fighting, happy to show off his combative ability, and takes great pride in his reputation as the mafia's strongest martial artist. For as hot-headed as he may seem, Chūya isn't impossible to reason with. In fact, he's rather reasonable when no one is pushing his buttons. Though the one man Chuuya can't stand is his partner, Dazai. Chuuya has an ability called the tainted sorrow that allows him to control gravity.
