狐斎宮 狐斋宫
The Kitsune Saiguu (Japanese: 狐斎宮 "Fox High Priestess"), also known as Lady Saiguu and the Hakushin Kitsune, was a prominent historical figure in Inazuma who was worshipped as a kitsune goddess. She was a descendant of the Hakushin Clan, was a close ally of the Raiden Shogun, Baal, alongside the oni Chiyo, and served a mentor-like role towards a shrine maiden named Kanade.

During a "dark disaster," likely the cataclysm five hundred years ago, the Kitsune Saiguu was among those who disappeared. She was consumed by a "dark will," and both her body and memories were broken down and turned into filth.
