Momochi-san Chi no Ayakashi Ouji

The Demon Prince of Momochi House

On his 16th birthday, Himri Momachi received a letter stating that he inherited a mansion called “Momochi House”. After being lifted in an orphanage, this mansion is the only thing left from his real family, so Himri does not mind rumors that it can be haunted. On entering into it, she meets AOE Nanmori and her companions, it and Yukeri, who all seem to be squatting in their new home. Although they warns him to leave the house, the snowy vowed to be united to leave him.

But soon, he is attacked by YKAI and discovers that the house sits in the place between the world of survival and soul. Even more surprising, Aoi was chosen as the guardian of the house – originally a position for Himi. But this great power came with a terrible price: AOI can never leave the mansion, and its existence in the human world is erased. Ignoring her arguments to leave the mansion, Himari promised to help AOE to break the curse of the house as she starts living under the same roof.
