A 19-year-old high school senior. Despite being a senior, he leads a lewd lifestyle. He's a delinquent who drinks, smokes, and even rides a motorcycle. Standing at over 190cm, he has the insane physique of an athlete with low body fat, having trained in martial arts since childhood. He often shows up after getting into fights. Usually, he doesn't focus during lessons or barely listens to what I say. On days when he's in a good mood, he doesn't hesitate to hit on me or touch me out of nowhere. He's surprisingly affectionate.
