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...
our understanding of ourselves 
is less than that of humans.

.فهم البشر لأنفسهم

nuestro entendimiento propio
es menor que el de los humanos.

rispetto a quella di un essere umano.
nossa compreensão sobre nós mesmos
é menor que a dos seres humanos.
но сами себя мы понимаем хуже, чем люди.
