Tetsuo Takahashi Wants an Interview

Tetsuo Takahashi Wants an Interview "Takahashi Tetsuo wa Kataritai" (高橋鉄男は語りたい)  is the first episode of Demi-chan wa kataritai.

Synopsis
Takahashi Tetsuo, a biology teacher at Shibasaki 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.undefined

Trivia

 * It's VERY rare for even four demis to be in the same location; they're a small minority born as a result of random mutation.
 * Saki is upfront about being a succubus with the rest of the staff so everyone knows why she keeps her distance.
