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. Quiet. Sleepy. Very calm. Bluntly honest. Observant. Analytical. Kind. Gentle at times.
