Chiaki has short, pale mauve hair that slightly curls outwards, though the locks on either side of her face curl inwards. She has short straight bangs split towards the right, a white hairclip resembling the spaceship from Galaga pinned to a lock of her hair. She has sleepy-looking blossom pink eyes. She wears a white button-up shirt with a dark teal-gray front placket. She wears a light pink ribbon tied around her neck in a bow, a pale beige pleated skirt, and teal-gray cardigan.
