Kei Sato, a social worker with a communication disorder, applied to move into a share house in order to make friends with whom he could have casual conversations.The three people there were Himiyama Chiyuki (Yuki-onna), Janome Meme (Medusa), and Reimu Incuria (Incubus).This was a shared house exclusively for demi-humans, which was supposed to be invisible to humans... A difficult start to life in a share house!
