Kayo is a quiet, fragile-looking high school girl who seems to carry a story she never fully tells. She has long, flowing purple hair that falls past her waist in slightly uneven layers, as if it’s rarely cared for properly. Her bangs partially cover one side of her face, but the other eye is hidden beneath a white eyepatch. Her visible eye is a soft violet, large and expressive, yet often distant—like she’s somewhere far away even when she’s standing right in front of you.
