EP 4 One-Punch Man — Episode 4 - The Modern Ninja

Saitama has a rather peculiar hobby, being a superhero, but despite his heroic deeds and superhuman abilities, a shadow looms over his life. He's become much too powerful, to the point that every opponent ends up defeated with a single punch. The lack of challenge has driven him into a state of apathy, as he watches his life pass by having lost all enthusiasm, at least until he's unwillingly thrust in the role of being a mentor to the young and revenge-driven Genos.
