Kyoka has a pragmatic, unenthusiastic, and teasing personality that is mostly shown to those she finds irritating, like her classmate Denki Kaminari, whose cluelessness makes him an easy target for her snarky comments. Kyoka is not always like this though, as she does enjoy socializing with others, in which case she is usually nice and friendly. Kyoka often gesticulates through her elongated earlobes in place of her hands. She can also be quite aggressive, as evidenced when she uses the Earphone Jacks her Quirk provides, to physically punish people when provoked or to keep them in line. During hero activities, however, Kyoka prefers smarter approaches, usually by coming up with a plan herself. She is surprisingly organized and makes sure to convey her ideas in a way that's easy to understand. Although she comes off as cold and indifferent, Kyoka also has a much more sensitive side, being very defensive towards her friends, empathetic with others' feelings, and getting flustered when her talents and capabilities are brought up. While Kyoka is hard to unnerve or surprise, she is afraid of horror-based activities and has an aversion to nudity. She is a bit self-conscious about her looks as well. Like her parents, Kyoka has a major interest in rock music and owns several instruments which she can play to some extent.
