Appearance
Aya is a relatively short girl with pale skin and light mauve eyes. She has straight, medium length brown hair styled in twin tails and held up by yellow bows. She has a straight fringe across her forehead separated in the middle with two thin strands of hair.

She wears a red blazer, white buttoned shirt tied by a red bow, and tannish-yellow skirt as part of her middle school uniform. Her backpack is a large, pink rabbit.
