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?!
Onii-chan!

¡Hermano!
¡Hermano!
Oh, fratellone!
Ah, Onii-chan!
