I randomly remembered this manga so the least I can do is leave a review despite being late? This series was one of the first ones I read about interactions between humans and non-humans in the context of education. The series itself is relatively straight forward, a decent guy is a teacher for demi-humans? Knowing the differences between themselves, he still treats them with diligence enforced with kindness. Sure it's not the most exciting, yet somehow it works very well? It must also be mentioned the biggest bonus here is knowing there is a lessened focus on ecchi factors. Sure there may be some preview, thenthe development goes back to what's really going on
