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...
I've never altered anything 
for a snake person before!
!لم أعدّل شيئًا لثعبان بشري من قبل
Für Schlangenmenschen
haben wir das noch nie gemacht …
Nunca alteré uno
para una persona serpiente.
Nunca alteré uno
para una persona serpiente.
Non ho mai modificato niente per un rettiloide!
Eu nunca ajustei nada 
pra uma pessoa-cobra antes!
Я никогда не подгоняла одежду 
под змеелюдей!
