The Demon Prince of Momochi House Vol. 4 (manga)

Himari Momochi inherits Momochi House, an estate that exists on the barrier between the human and spiritual realms. All knowledge of Aoi’s existence has been expunged from the outside world, but there is one who still faintly remembers him—Aoi’s childhood friend Hayato Hidaka. Hayato seeks out Himari, but it is said anyone who becomes involved with him will be cursed!
