A pack of monsters calling themselves the "Clan of the Seafolk" arrive on the shores of City J intent on invading the land. When the hero sent to fight them is defeated easily by the Deep Sea King himself, Saitama and Genos head for the city to help.
You think you have the strength
to rule the surface all alone?
هل تظنّ أنّك تملك القوّة لتحكم اليابسة لوحدك؟

à toi tout seul ?
Pensi di poter conquistare
tutta la superficie da solo?
