One Punch Man” follows Saitama, an ordinary man who becomes a superhero just for fun. After three years of intense training (100 push-ups, 100 sit-ups, 100 squats, and a 10 km run daily), he becomes so powerful that he can defeat any enemy with a single punch—which ironically leaves him bored and unfulfilled.
Living in a world constantly threatened by monsters and villains, Saitama joins the Hero Association to find meaning in his battles and gain recognition. However, most people underestimate or ignore him, and his immense power goes largely unnoticed.
