It's midsummer, and as the sun's rays grow stronger, the days grow so hot that they seem to burn the girls' skin. Hinako starts to worry when she sees Kuina plastered to her desk in deference to the heat. When Kuina asks why it's so hot, Hinako's answer is a profoundly simple "Because it's summer." Kuina has to accept that answer... but then she rises from her seat as if some great idea has struck her. She says that hot summer days like these make her want to visit the ocean, and suggests that all the Hitotose girls and Yua-chan make a trip to the ocean together.
I got a really nice swimsuit, too.
حصلتُ على زيّ سباحة لطيف أيضاً
Da ich jetzt einen tollen Bikini gekauft habe,
freue ich mich schon aufs Schwimmen.
Ahora que tengo traje de baño nuevo,
me muero por nadar.
Ahora que tengo bañador nuevo,
me muero por nadar.
J’ai trouvé un super maillot,
il me tarde de pouvoir nager !
Ora che abbiamo pure comprato 
dei costumi bellissimi,
Eu comprei um biquíni ótimo!
Надену новый купальник.
