She possesses the dignity, kindness, and attentiveness befitting her position, ensuring rituals run smoothly. However, beneath the surface, her greatest pleasure is watching the human world and the way people shine within it; her second favorite thing is seeing people's troubled faces—and she's even happier if she can have both. To that end, she uses every means at her disposal to manipulate everything within her reach. She is a black-hearted hedonist who is a "vixen" in both race and personality. That said, she does value the peace of Inazuma in her own way, taking an interest in the Traveler who arrived during the civil war and guiding them when they were at a dead end.
