Aoi is a young, pretty-faced teenager with long blue/black hair and blue eyes. Early in the series she would commonly wear an open white trench-coat, cargo pants, and bandages covering her chest; revealing her stomach. She also wears a black string around her neck with a golden ring hanging in the middle.After handing over the leadership to Nene she begins to wear an average school girl uniform consisting of a white blouse that is slightly unbuttoned, a red loosened tie and dark blue skirt covering her thighs. The day after the victory in the volleyball match her appearance is slightly changed. She looks more dignified than before. Along with her usual uniform, she now wears a dark green coat with a St. Ishiyama label on it. The blouse is now properly buttoned at the top. The tie is also tightened and is tucked under a v-collared sweater.However, after reclaiming her position as leader of the Red Tail, she returns to her initial outfit.
