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.

sobre hacerlo con los chicos, ¿eh?

mas já que com o de garotos
 é diferente, então...
а вот представить подобное
с парнем тебе ещё неудобно?
