The Demon Prince of Momochi House - S01

On her 16th birthday, orphan Himari Momochi learns her late parents left her a house-one she never knew existed. Eager to connect with her family’s past, she visits the supposedly haunted property, only to find three young men already living there: Aoi Nanamori, who claims to be the house’s guardian, and his two familiars, Yukari and Ise. They let her stay the night but insist she leave the next day to avoid the dangerous ayakashi-wandering spirits that prey on humans. But the ayakashi don’t harm Himari, and she refuses to leave. She soon learns Aoi never chose to be the guardian; he’s bound to the house, cut off from the outside world. Moved by his plight, Himari vows to free him and convinces the three to let her stay as their landlady. Yet the enigmatic Kasha, who sends hostile ayakashi after the house, appears to have sinister designs for Aoi’s fate.
