The supernatural fantasy romance The Demon Prince of Momochi House continues several years later with Himari and Aoi living together in her new Momochi house.

Aoi Nanamori had been trapped for a long time in Himari Momochi’s ancestorial house as its spiritual guardian, the Omamori-sama. Several years later, Aoi has returned to Himari as a human, and the couple is living together—though strangely the two are now farther apart in age...

As before, shikigami and yokai cluster to Aoi’s side. Things are lively at Himari’s newly purchased "Momochi House," and mysterious beings from the spiritual realm have already found their way there!
