Monster Musume: Everyday Life with Monster Girls (2015)

In a world where humans co-exist with fantasy beings, an exchange program is created to enable the mythic beings to make a place for themselves within human society. As a part of this program, the young teenager Kurusu Kimihito must share his flat with a group of mythic young ladies: the snake girl Miia, the bird girl Papi, the horse lady Centorea, and many others. It's now Kurusu's duty to watch over all these girls and see they cause no trouble - but all these girls have fallen in love with Kurusu and will do anything to be with him.
