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.
I never expected to meet someone 
in this school from so nearby.
لم أتوقّع أن ألتقي بأحد في هذه 
.المدرسة يعيش على مقربة
Unfassbar, dass ich auf dieser Schule
jemanden aus meiner Nachbarschaft treffe.
No creí encontrar a alguien
de la misma área.
No esperaba encontrarme
a alguien de mi zona.
Je ne pensais pas
retrouver des voisines ici.
Non mi sarei mai aspettata di incontrare qui
qualcuno che abita vicino a me.
Jamais me passou pela cabeça encontrar
 alguém aqui de tão perto.
Не думала, что встречу
в этой школе соседей.
