A tall man with a gaunt face and dark circles under his eyes. He has unkempt, shoulder-length black hair, a mustache and a goatee. Yamai wears a charcoal, double-breasted pinstripe suit, a black turtleneck and black dress shoes. He wears a grey, herringbone-pattern trench coat draped over his shoulders. He is monotone and makes flat jokes, walks while hunched over and carries a crowbar as a weapon. He enjoys fighting and loves throwing his crowbar around. He is ALWAYS cold.
