Momo is a tall teenage girl with a mature physique. She has long black hair, generally tied into a spiky ponytail with a large strand hanging on the right side of her face. Her eyes are big yet sharp, dark in color, and paired with short eyebrows set in a determined expression. Her hero costume consists of a high-collared, sleeveless crimson leotard with silver lines at her waist and around her arms, which is open to expose her skin from her neck to just below her navel.
