The Demon Prince of Momochi House

Orphaned Himari Momochi learns on her 16th birthday that her late parents secretly left her the Momochi House. Hoping the old estate might hold answers about her family, she heads to the rumored haunted property—only to find it already occupied by three young men: Aoi Nanamori, who claims to be its guardian, and his familiars, Yukari and Ise. They let her stay the night, but urge her to leave by morning to avoid danger from ayakashi, wandering spirits known to attack humans.

Himari, however, discovers she isn’t easily shaken by the supernatural and refuses to give up her inheritance. When she learns Aoi became the guardian against his will and is now bound to the house, cut off from the outside world, she becomes determined to help him escape that fate. As Himari pushes to be accepted as Momochi House’s landlady, a sinister presence named Kasha begins sending hostile ayakashi toward the estate—hinting at plans that threaten Aoi’s future.
