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?!
Illya, you're such a child. 
This is what they call "sexy."
Du bist noch so ein Kind, Illya.
Qué infantil. Eso es lo que llaman sexy.
Qué infantil. Eso es lo que llaman sexy.
T’es vraiment une gamine.
Illya, sei proprio una bambina. 
È quello che si definisce essere provocanti.
Illya, como você é criança. Isso
 é o que chamam de ser sexy.
