生亀 勇人

Takeo's only son. A first-year student at Meirin Academy. He has a selfish personality and thinks that most things can be solved with money and violence. He trains his body, but he also uses muscle-building supplements, making him quite muscular for a student. He is stronger than most and would be able to win a fight with someone his age, but he lacks the skills to fight properly against someone with martial arts experience.
