Kyoka is a young, petite girl with a slender build. She has black, triangular 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. She also has two chin length strands framing her face, and keeps the rest up to her neck. 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. At U.A, she wears the regular U.A. uniform for female students. It is topped with a gray dress jacket, two teal stripes, two pockets with folds, and two golden buttons. Underneath, she wears a white dress shirt, a red tie with a small, golden button, and a teal pleated skirt. Her hero costume has a black leather jacket, long salmon-colored shirt with several rips at the collar and hem, black pants, and boots with stereos built into their shafts. She also has two small, triangular red paint marks just below her eyes, a plain black choker, and white fingerless gloves. After the Final War, Kyoka wears a whitish-gray, shell-shaped prosthetic ear over her left, where an artificial earphone jack is dispensed from the bottom. Kyoka has a pragmatic, unenthusiastic, blunt, and teasing personality that is mostly shown to those she finds irritating, like her fellow 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, most notably with Momo Yaoyorozu and the other girls in her class. Kyoka often gesticulates through her elongated earlobes in place of her hands. She can also be quite aggressive, evidenced by when she uses the Earphone Jacks her Quirk provides, to physically punish people when provoked or to keep them in line, most notably Denki and Minoru Mineta. 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. Despite the fact that 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 and style as well.
