Takahashi Tetsuo, a biology teacher at Shizaki High School, has been fascinated with "demi-humans," beings with characteristics that differ just slightly from humans, since he was in college. He wishes he could have a chance to talk with one, but since the demi-human population is fairly low, he's never even met one. But then the school gains a new math teacher, Satou Sakie... who happens to be a succubus.
But I'm not a teacher for nothing, you know.

depuis longtemps.
Ma c'è un motivo per cui sono un professore.
De qualquer jeito, já sou macaco velho.
Но я уже не первый год работаю учителем.
