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.
And yet you ruined them!
!إلى أنّك أفسدتهما
Du hast mir das versaut
und dafür wirst du büßen!
Je ne te pardonnerai pas
de les avoir défigurés !
Non ti perdonerò per avermeli guastati!
