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.
I've come to kill you.
Your deaths are inevitable!
!أتيت لأقتلكم. لا مفرّ من موتكم
Das wird euch nicht retten,
Dans tous les cas, vous mourrez.
Autant que ce soit par moi.
Morirete in ogni caso.
Perché io vi ammazzerò.
