One-Punch Man

Though he's been doing the hero gig for three years, Saitama realizes that the public knows nothing about him. Determined to get a little recognition, he decides to become a pro hero.

When Saitama learns that C-class heroes who don't fight bad guys are dropped from the hero registry after a week of inaction, he heads out to find any criminals or monsters to stop.

An enormous meteor hurtles toward City Z, forcing the Hero Association to ask its S Class heroes to respond.

Saitama and Genos head to the shores of City J to stop a pack of monsters calling themselves the "Clan of the Seafolk".

As the battle with the Deep Sea King reaches its climax, more heroes fall to the aquatic despot's brutal attacks.
