The grand event for elementary schoolers is finally here--Summer Break! In preparation for the long-awaited trip to the beach, Illya and the others go with their classmates to pick out new swimsuits and carry on in front of the skimpy clothing♪ While they're out, Kuro runs out of mana and calls Illya away to an empty stairway platform. But Mimi catches sight of them in the act?!
Let's behave and choose our swimsuits quietly.
Wir sollten uns benehmen und
uns in aller Ruhe Bikinis ausuchen …
Comportémonos y compremos 
nuestros trajes de baño en paz.
Comportémonos y compremos

Choisissons nos maillots
dans le calme.
Cerchiamo di comportarci bene 
e scegliamo i costumi.
Vamos nos comportar e escolher
 nossos biquínis com calma.
