Bazett's barrier was supposed to prevent surprise attacks from the dolls, however Illya finds a little girl, Erica, sneaking into their school. For some reason Erica calls Illya "Onee-chan", and the two of them quickly hit it off. Meanwhile, a man claiming to be Erica's father appears. He seems kind at first glance, and while he came to pick up Erica, he's also...?!
Sorry, Erica-chan! I'll stop her at once!
Tut mir leid, Erica-chan.

¡Lo siento, Erica-chan! ¡La detendré!
¡Lo siento, Erica-chan! ¡La detendré!
Désolée, Erika.
Scusa, Erika! Ora la faccio smettere!
Desculpe, Erica-chan! 
Eu vou fazer ela parar!
