Aura is, as a demon, an "articulate monster" who is individualistic and harbors no sense of "empathy". A monster of human appearance who only speaks human language not in order to communicate, but to deceive. A ruthless killer who feeds on human flesh. Aura appears to be a young woman of short height, slender body, pale skin, a rather childish face, thick magenta hair in multiple braids, and large slit-like blue eyes. She has long horns.
