Kyoka is a petite, fair-skinned girl with a slender build. She has triangular onyx eyes with notably long lower eyelashes and small eyebrows. Her dark-purple hair is chin length, with an asymmetrical fringe that has two reflections shaped like sound waves on either side. She has flexible, plug-like earphone jacks hanging from each of her earlobes; they act like extra limbs. Kyoka has a pragmatic, unenthusiastic, blunt, and teasing personality that is mostly shown to those she finds irritating.
