Medaka has a beautiful body, and especially large breasts, which she has no scruples about showing off. She has very long purple hair the reaches down to her waist and bangs that barely overlap her red eyes, as well as a semi-straight ahoge. Medaka wears the uniform of the Student Council, black as opposed to the usual white. Her original uniform displays her impressive cleavage and has a shortened skirt, but after Hitomi Hitoyoshi arrives at the school, she modifies Medaka's uniform to cover her breasts and lengthens the skirt. During the battle to decide the academy's new Student Council, Medaka wears the Student Council's Battle Attire Red Model.
