One-Punch Man

Saitama is a hero who only became a hero for fun. After three years of “special” training, though, he’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, and it turns out that being devastatingly powerful is actually kind of a bore. With his passion for being a hero lost along with his hair, yet still faced with new enemies every day, how much longer can he keep it going?

Saitama, alongside his cyborg disciple Genos, is ready to begin his official duties as a professional hero. But when a new friendship and interest in martial arts prove distracting, the Hero Association is left to deal with a sinister new wave of monster attacks on their own. To make matters worse, their heroes are being hunted! Is Earth doomed, or will Saitama save the day with one punch?

Alongside Genos, his faithful disciple, Saitama performs his official hero duties as a member of the Hero Association. One day, monsters claiming to be from the Monster Association suddenly appeared, taking a child of the Hero Association executive hostage. The S-class heroes gather and plan a raid on the Monster Association hideout to rescue the hostage. Meanwhile, Garou, a “human monster” who was taken by the Monster Association during a battle with the heroes, awakens in the Monster Association hideout.
