Yomi is a keeper of secrets and has a temper to match the storms, coming and going at its own idle pace, striking with the fury of lightning or consistent ease of rain. When asked about where she's from, her story always changes. She was from a desert temple, a rainforest village, a city in the stars. Initially, she seems to be more interested in pursuing her own wants and desires, though when one is lucky enough to know her better it becomes clear she cares deeply for those she considers friends or family. As such, she has found herself as a member of a small clerical group, acting as sometimes their face, sometimes their caretaker, and always as the storm that strikes down their foes.

Yomi has fair skin, purple eyes, and thigh-length pink hair with red makeup painted at the corners of her eyes. Being a Kitsune, she has similarly pink fox ears that are perpetually turned downwards, and what appears to be a single matching pink tail. She wears a white kosode with detached sleeves and a red hakama, both with dark purple insides and accent pieces, complete with a large black bow on the back.
