Kyoka is a petite, fair-skinned girl with a slender build. She has triangular, lazy-looking onyx eyes with notably long lower eyelashes, and rather small eyebrows. Kyoka has a pragmatic, unenthusiastic and teasing personality that is mostly shown to those she finds irritating. Kyoka is not always like this though, as she does enjoy socializing with others, in which case she is usually nice and friendly. Kyoka's Quirk (Earphone Jack) allows her to plug the jacks that hang from her earlobes into all sorts of things and channel the sound of her heartbeat into them; causing havoc inside the plugged objects. It's also used to catch sounds and vibrations from her surroundings.
