One Punch Man: Season 2 Blu-Ray

After three years of "special training," Saitama's become so strong that he's practically invincible. In fact, he's too strong - even his mightiest opponents are taken out with a single punch. Alongside Genos, his faithful disciple, Saitama begins his official hero duties as a member of the Hero Association, while Garou, a man utterly fascinated by monsters, makes his appearance.
