GENSHIN IMPACT - Kitsune Saiguu

"Do not be blinded. Do not waver. Keep walking the path that you believe in."

Kitsune Saiguu one of Raiden Shogun/Ei's closest friend

Wikia Time:

The Kitsune Saiguu (狐きつね斎さい宮ぐう "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 Asase Hibiki.

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.
