Bazett's barrier was supposed to prevent surprise attacks from the dolls, however Illya finds a little girl, Erica, sneaking into their school.

I can't lose to this airheaded girl 
in bloomers with a muddy face!
¡No perderé contra una niña torpe

Eu não posso perder para essa 
cabeça-oca com a cara suja de lama!
