Fuyuhiko Kuzuryu is the Ultimate Yakuza. Fuyuhiko is the heir to the Kuzuryu yakuza clan, the largest criminal syndicate in the nation, with a membership surpassing 30,000. He grew accustomed to the Kuzuryu Clan's way of settling disputes through violence, leading him to believe that as long as he bore his family name, he would always be surrounded by a mountain of dead bodies. His upbringing toughened him so much that he no longer cried about anything, including losing a fight by second grade. Being treated with caution by non-clan members was second nature to him due to his status. Ever since Fuyuhiko was too young to understand, he had often witnessed his parents' frequent fights. It involved his mother's various attempts to kill his hotheaded father during minor arguments that quickly escalated. There were a few instances when Fuyuhiko was nearly killed in the aftermath of his parents' fights, but his assigned hitman, who had accompanied him since infancy, Peko Pekoyama, was always there to protect him. Peko, on the other hand, noted that despite being a yakuza, Fuyuhiko had a kind heart. He would constantly question and worry about his position, believing that his little sister, Natsumi, was more deserving of succeeding as clan head. He was fond of her and always helped her when she needed it, dubbing her the Ultimate Little Sister. Although Natsumi was an annoying little sister who loved making a fool out of him, on top of being self-centered, selfish, and extremely arrogant, Fuyuhiko praised her talent for getting people to do what she wanted. He believed that this skill was what made her deserve the Ultimate Yakuza title more than he did. She was even called the reincarnation of their uncle. When a faction within the clan wanted to make her the next leader, Natsumi refused, claiming she was only amazing because she was Fuyuhiko's sister. Fuyuhiko could not accept this and insisted that she could lead while he lived on his own, as he believed she was better than him at everything. However, she was murdered by Sato while she was in the reserve course of Hope's Peak Academy. He is a slim male with a refined appearance, often described as having a "baby face." Because of his fairly short build, Fuyuhiko generally presents an overly aggressive demeanor to assert that he is, in fact, a tough gangster. He has dusty blond crew-cut hair, with a distinct pair of curved lines shaved on each side of his head. He also has freckles along the bridge of his nose and a birthmark near his mouth on the right side. His eyes are gold, and he has permanent blush marks on both cheeks. Befitting his title, Fuyuhiko dresses in traditional yakuza fashion: well-tailored suits. During the Killing School Trip, he wears a two-piece suit consisting of a dark pinstripe jacket and pants over a white dress shirt. His tie is brown-black with an animal skull emblem on it, and he wears black dress shoes with a platform heel. On his left lapel is a pin in the shape of the emblem of the Kuzuryu family, and he wears two silver rings on his right hand. He later wears a black eyepatch with a white, round dragon pattern. Even though many Yakuza members get tattoos, Fuyuhiko states that he has not been tattooed yet. Fuyuhiko is initially incredibly stand-offish, always in a crappy mood, and rude to the other students. He claims he's not going to play at being friends with anyone, and considers it not worth his time and beneath him. When Fuyuhiko interacts with others, whether by choice or not, his attitude is combative and irritable. He is easily angered and often resorts to threatening or insulting others when they disagree with or complain about his actions. He badmouths everyone, using names like "bastard," "dumbass," and "motherf--ker." He wants to prove that he can survive on his own without relying on the Kuzuryu Clan or his assigned hitman, which is why he pushes Peko away and loathes being treated like a kid.
