Kyouka is a student at UA attending to become a professional hero in the future. Her Quirk, or power, is called Earphone Jack, and basically allows the earphones that are her actual ear lobes to extend and connect with any object or part of her body, amplifying her heartbeat out to attack. She can also use the jacks themselves as whips or plug them into her boots to aim them in a certain direction. She is a big fan of rock music.
