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...
