Events
In a scenario 500 years ago, a schism between the Hiragi and Ichinose house was started by the eldest Hiragi son who assaulted both a woman of the Ichinose house, and his own brother before exiling them. While the Hiragi had had the Order of the Imperial Demons at its disposal, it do not attack the nascent Order of the Imperial Moon in a move to shame them. The eldest son's child would be born to the Ichinose woman and become the head of the Order of the Imperial Moon. Denigrating the Ichinose house has persisted to the present day from this incident.

Capabilities
In consolidating power, presently, the house system has survived the apocalypse where prominent houses have army units and advanced technology including weapons such as Cursed Gear at their disposal. Tenri Hīragi, using the Japanese Imperial Demon Army has exerted some degree of influence over a vampire populated Japan. Kureto Hīragi in particular envisions his house leveraging control over the human populations of the world, with the vampire order of the world challenged.

The Sangu house wields considerable influence based on the Japanese Imperial Demon Army position that Aoi Sangū enjoys, and the merits afforded to Mitsuba Sangū on account of her family name. Guren Ichinose harbours destructive intent towards the Hiragi house to end its treatment of others. Mito Jūjō and Norito Goshi are prominent members of their respective families where they represent their name occupying senior positions in the Moon Demon Company.
