A new student, the Antarctican Quetzalcoatl Sassassul, suddenly transfers into the girls' school one day, much to the intrigue of everyone in the class. But for some reason, Himeno seems to have experienced some sort of childhood trauma involving Antarcticans. The new student is as kind and friendly as can be, but Himeno just can't shake her fear...

Meanwhile, everyone in the class has lots of questions for Sassassul...
Look, you're not some 
burglar who needs a mask.

Du siehst aus wie ein Einbrecher.
No eres un ladrón
que necesite una máscara.
No eres un ladrón
que necesite una máscara.
Enfin, t’es pas une voleuse,

Senti, non sei mica una ladra
che deve coprirsi la faccia.
Olha, você não é uma ladra
pra precisar usar máscara.
Ты же не грабитель, чтобы носить маску.
