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!
No one will know unless you strip, 
so it's not a problem.
Wen kümmert’s, solange du
dich nicht nackig machst?
Nadie lo sabrá si no te lo quitas.
Nadie lo sabrá si no te la quitas.
Tant qu’on se déshabille pas,
tout roule !
Che problema c'è, 
basta che non ti spogli e non lo saprà nessuno.
A não ser que você tire a yukata, ninguém
 vai saber, então não tem problema.
