Kyoka Jiro

Kyoka Jiro (耳じ郎ろう響きょう香か Jirō Kyōka?), also known as the Hearing Hero: Earphone Jack (ヒアヒーローイヤホン＝ジャック Hia Hīrō Iyahon Jakku?), was a student in Class 1-A at U.A. High School, training to become a Hero.

Kyoka is a petite, fair-skinned girl with a slender build. She has triangular onyx 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. Following the Paranormal Liberation War, she gains a small scar on her right earphone jack. During the Final War, her left ear and earphone jack are blown off by All For One.

Unlike the other students, Kyoka sometimes wears a waistcoat over her school uniform, in place of the usual U.A. blazer.

Her hero costume consists of 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.

Later on, her costume gains a set of headphones with two bracelets that double up as her amplifiers and she changes her face paint to two larger chevron-shaped marks. Shortly after the Final War, Kyoka wears a prosthetic in place of her left ear and earphone jack, with the jack being flesh-colored with the front end separated by a shade of pink.[7][8]

Eight years after the Final War, Kyoka has grown taller, and the back part of her hair has grown out and now reaches her shoulders. Her updated hero costume now consists of a black sleeveless jacket over a white tank top, a new set of silver and purple headphones over her prosthetic left ear, and two mid-length black bands and salmon gloves for her Amplifier Jack. She also wears black nail polish. Her boots now have two holes in the soles of them.

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.[9] 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.[10][11][12] 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, becoming noticeably upset when she was not seen as attractive by Minoru, and attacking Denki and Yuga Aoyama for commenting that her dorm room was unladylike.

Like her parents, Kyoka has a major interest in rock music and owns several instruments which she is able to play to some extent. However, she seemed to be somewhat embarrassed about her interests at first, because she perceived them as completely unrelated to heroism, but thanks to a great presentation during the U.A. School Festival, she was able to outgrow that mindset.
