One Punch Man

Saitama only became a hero for fun, but after three years of 'special' training, he finds that he can beat even the mightiest opponents with a single punch. Though he faces new enemies every day, it turns out being devastatingly powerful is actually kind of a bore. Can a hero be too strong?
