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?!
She'll be wearing underwear, so who 
cares if they're a little see-through?
Ein wenig durchsichtig macht doch nichts,
sie trägt ja Unterwäsche!
Llevará ropa interior debajo, ¿qué 
importa si se transparenta un poco?
Llevará ropa interior debajo, 
¿qué importa si se transparenta un poco?
Indosserà la biancheria intima,

Ela vai estar com as roupas de baixo, 
então que mal tem ser transparente?
