Momiji has long red hair that fades to a somewhat golden and orange color. Her eyes are green and she wears a strange bean bag-like hat on her head. Her casual clothes consist of a red vest, a loose black belt with chains attached around her waist, and a black skirt with white ruffles. Momiji is mischievous, confident, and bold. Kind to her friends and cold to everyone else, she is a realist and a genius. She could get top grades at school if she tried; however, she refuses to conform.
