Lum is a very beautiful and voluptuous young woman with yellow eyes and long green hair. Like all of her kind she has sharp teeth, pointy ears and small yellow horns. For her everyday attire she wears a yellow tiger striped bikini with matching boots. Like all the women on Oniboshi, Lum lives in a simplistic yet cozy rock cave. Lum has no sense of embarrassment or shame, since openness is deeply entrenched in Oni culture, and indeed enjoys teasing and being impish.
