Mina is a girl of medium height, possibly set a little more broadly than some of her other female classmates, with healthy thighs. Due to her Quirk, her skin is a light shade of pink, and she has somewhat square shaped eyes, with a black sclera and light yellow irises, and notably long eyelashes below and around the sides of her eyes. Minoru Mineta comments that "she's got a super athletic body."

Her face is framed by short hair, fluffy and unruly, which is a pink color, slightly darker than her skin's. She has two thin, pale yellow horns protruding from her head, hooked squarely and leaning diagonally to opposite sides, which seem to be slightly flexible, able to bend a bit to each side. During school hours, she wears the normal female U.A. uniform.
