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!
I can't have you underestimating 
my mastery at falling!
Wenn ich was kann, dann
Hinfallen und Wiederaufstehen!
¡No subestimen mi 
título avanzado en caídas!
¡No subestiméis mi título 
avanzado en caerse!
Ne sous-estimez pas
le maître en réception que je suis !
Non sottovalutate la mia abilità nel cadere!
Não posso deixar vocês subestimarem
 a minha capacidade de cair no chão!
