Kyoka Jiro has a pragmatic, unenthusiastic, and mocking personality that is mainly shown to those she finds irritating. Kyoka Jiro is a girl of small stature, with light skin and a slim build. She has triangular, lazy-looking onyx eyes with noticeably long lower eyelashes and rather small eyebrows. Kyoka's Quirk, Earphone Jack, gives her headphone-like jacks in her ears which can stretch up to 6 meters and plug into all kinds of things, sending out amplified sound waves.
