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. She sports calf-length red boots with heels, which dip sharply down in the center, two gold utility belts around her waist, with the back holding her books on composition information, and another thinner one around the top of her chest, below her shoulders. The design choice allows her to create items from as many points in her body as possible, as her Quirk can only be used if her skin is exposed.
