Nagisa has fair skin, short black hair, brown eyes, and a fairly small bust compared to the other girls (with only Lobelia, Marie Rose and Kanna's busts being smaller) and overall appears mature. She wears leggings as well as a white one-piece swimsuit with a thong underneath. Nagisa also was frequently seen with a scarf. Owing to her familial ties to Misaki, she shares a similar facial structure to Misaki, as well as the same eye color and roughly the same height.
