It's summer. The gang's on a southern island, and there's cute girls in swimsuits abound. Arata's cooking yakisoba for some reason, but these things happen.

from any experimentation
Ich verbiete euch auf jeden Fall,
je wieder etwas zu tun,
En fin, tienen estrictamente prohibido 
hacer cualquier cosa que pueda
En fin, tenéis estrictamente prohibido
