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! It's a festival! A festival!
Ja! Auf zum Fest, auf zum Fest!
¡Sí! ¡Festival, festival!
¡Sí! ¡Festival, festival!
Già! La fiera! La fiera!
Isso aí! Festival! Festival!
