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?!
Since Miyu-chan's staying over, 
having everyone together is better, isn't it?
Wenn Miyu-chan schon
mal hier übernachtet,
Es mejor estar todas juntas 
ahora que vino Miyu-chan, ¿no?
Es mejor estar todas juntas 
ahora que ha venido Miyu-chan, ¿no?
Visto che Miyu si ferma da noi, 
è meglio stare tutte assieme, non trovi?
É melhor ficarmos todas juntas já que
 a Miyu-chan está dormindo aqui, não?
