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!
Sorry I could only join you for part of it, 
after you asked me to come.
Entschuldige, dass ich trotz deiner
Einladung nur kurz dabei war.
Lamento no haberlas acompañado hasta 
ahora, luego de que yo las invitara.

Désolé de n’arriver que maintenant
alors que vous m’avez invité…
Mi spiace di essermi unito a voi solo adesso, 
anche se mi avevate invitato.
Desculpe só poder lhes dar atenção agora,
 depois de me convidarem e tudo mais.
