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. Her most prominent features are the flexible, plug-like earphone jacks hanging from each of her earlobes; they act like extra limbs that she is able to control at will, and change their length if so desired.
