Shuto Hiiragi is a 25-year-old yakuza who lives aimlessly day by day. He spends his free time womanizing or fighting. He occasionally has women he treats as playthings or lackeys hanging around, but he pays them no mind. He has no qualms about using violence regardless of his surroundings. He gets his money by swindling women or mooching off his followers. A heavy smoker, he lights up almost every day. He had a rough upbringing, having been abused by his mother during childhood; his father disappeared when he was very young. He has flower-patterned tattoos stretching from his neck to his back and wears piercings. He is unsociable and foul-mouthed, though not vulgar. He has a muscular, sturdy build.
