Kamuy-huci (カムイフチ, Kamui Fuchi) is the Ainu kamuy (goddess) of the hearth.
Kamuy-huci, insulted, challenges her rival to a duel of sorcery, from which she emerges victorious with relative ease.
Those who pollute a hearth or fail to maintain proper domestic relationships are said to incur her punishment.
In addition to being the center of the Ainu household, the hearth was considered a gateway by means of which humans and kamuy could communicate.
Transmigration is a tenet of Ainu mythology, so it was doubly important for the hearth to be kept pure, because the souls of the departed who lived there would be assigned to new bodies in time.
