Synopsis
When I opened the door, there was a girl in a sailor suit in front of me. As a resident of the room, I was rigid ... and the girl shouted. "Wow! You're free!"-This was the first contact between me, Katsuki Moriya, and her, "Zashiki-warashi no Miran." I was forced to live with Zashiki-warashi, who looks like a strange girl. In addition, Toyoashi Gakuen, which I will be attending from this year, is full of strange people, so what will happen to me in the future ...?
