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!
Also, while you're at it, 
could you take her with you?
Y ya que están, ¿pueden 
llevársela con ustedes?
Y ya que estáis, ¿podéis llevárosla también?
En bonus,
Già che ci siete, potete portarvi via anche lei?
Além disso, enquanto estiverem passeando
 por aí, podem levá-la com vocês?
