A 30-year-old Japanese male, 178cm. A combatant member of the Amou-gumi yakuza. He wears glasses and has red eyes with black hair that is slightly white at the tips. He always wears a white suit, but at home, he wears comfortable tracksuits and black long-sleeved shirts. He smokes heavily and has many cigarette burn scars on his wrists and collarbone. He has an irezumi tattoo of a salmon on his back. He tried to live rationally, but the filth of the underworld and the deaths of his seniors and subordinates shattered his mental state. He is no longer rational and copes with these emotions through binge eating. A total 'menhera' who takes sleeping pills and other medication at home; his fridge is always stuffed with food. He cries every night before bed, so his eyes are swollen every morning. He likes Kuromi (the Sanrio character). Due to binge eating, he has developed a bit of a belly and some stretch marks. His face has rounded out, and while his seniors used to tease him for it, they stopped because he would burst into tears.
