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!
Yeah, I've never seen the

Okay, ich hab selbst noch

Sí, yo tampoco he visto cuando los tiran.
Giusto, nemmeno io ho mai visto prima 
il momento del lancio.
É, eu nunca vi o momento em 
que eles são disparados também.
