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!
You can't calculate the fun 
you have at a festival!
Wie viel Spaß man an einem Fest hat,
lässt sich nicht berechnen!
¡No puedes calcular cuánta 
diversión tendrás en un festival!
¡No puedes calcular cuánta 
diversión tendrás en un festival!
Un calcul ne peut pas mesurer
combien on s’éclate dans un festival !
Non puoi prevedere
 quanto ti divertirai ad una fiera!
Não dá para se calcular a 
diversão que se tem num festival!
