Illya's enjoyable summer isn't over! After changing into a yukata, she joins the usual gang and heads to a local festival. As Illya enjoys yo-yo fishing and lottery drawings at the festival, she realizes something dire--she was supposed to wear underwear beneath her yukata! A great tragedy befalls upon her!
Oh, you're back.
Ah, da seid ihr wieder.
Volvieron.
Habéis vuelto.
Les revoilà !
Oh, siete tornate.
Ah, vocês voltaram.
