Video trailer



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?
The story takes place in the city of Z of Japan at a time when the world full of mysterious monsters with tremendous power has appeared and caused so many disasters. But it is here that a superhero punches and dies, can easily defeat and destroy these monsters. Because of this rare talent, there are many doubts about the true ability of the superhero, even he never received any trust from the people.
