It's time for a field trip to the beach, and the gang's getting ready. But who wants to see Kazuma in a swimsuit?

I don't know what a field trip is,
Ich weiß zwar nicht,
was der Ausflug genau ist,
No sé bien qué es un viaje de campo,
même si j’ignore ce qu’on fait
en classe de mer,
Eu não sei o que é uma excursão,
