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.
Yeah, I do! I want to!
!نعم، أريد! أريد ذلك
Ja, will ich.
Ich will Blut schlürfen.
Sí, eso quiero.
Sí, eso quiero.
Oui, tout à fait, j’en rêve !

Да, бывает, хочется!
