Kyoka Jiro (耳じ郎ろう響きょう香, 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), is a major protagonist in the My Hero Academia manga and anime series. She serves as the deuteragonist of the U.A. School Festival story arc.
Kyoka is a student at the prestigious U.A. High School training to become a Pro Hero. She is a part of Class 1-A of the Heroes Studies course. Jiro's quirk, Earphone Jack, affords her with long, controllable earlobes that function like headphone cables.
She is voiced by Kei Shindō in the Japanese version of the anime, and by Trina Nishimura in the English version of the anime. Her singing voice in both versions was provided by Chrissy Costanza.
Kyoka is a medium height girl with a slim build, lazy looking black eyes with small pupils and short, dark purple hair with an asymmetrical fringe and two chin-length bangs on either side. One of her most notable features is her Earphone Jacks hanging off each of her ears, due to her Quirk. Sometimes, instead of the U.A blazer, Kyoka wears the waistcoat.
Her hero costume consists of a black jacket, ending at her waist and the sleeves at her wrists, a pale red shirt with large rips at the hem-line and collar. She sports large black boots to use her Quirk with.
Kyoka also wears a plain black choker, black tights, white fingerless gloves and two red tear-drop shaped marks below her eyes.
Kyoka is a straight-forward and calm girl who, despite her usually unenthusiastic demeanour, has a teasing side towards others, most notably Denki Kaminari who finds his dumbed-out and short-circuited face to be funny. Despite this, she is friendly towards most her classmates and enjoys hanging out with them.
Kyoka can be aggressive when angered, often using her Earphone Jacks to punish those who get on her bad side, key examples being Denki Kaminari and Minoru Mineta during their perverted antics. While often coming off as cold however, Kyoka does also have an insecure side towards her own traits, being self-conscious of her appearance and being slightly affected when Mineta didn't comment about her while trying to peek on the girls.
When the occasion arises, Kyoka can also prove to be surprisingly intelligent, able to utilise Kaminari's Electrification Quirk to defeat villains at the USJ by using her classmate as a "human stun-gun". She also came up with the idea of using Koda's Quirk to use bugs to defeat Present Mic during the Final Exams.
Furthermore, Kyoka also possessed a complex regarding her passion for rock music and became embarrassed and reluctant when others inquired about it. It's revealed that this was because she perceived her passion as being unrelated to heroism, but eventually became motivated when taking the role of head singer during the School Festival. After this, Kyoka completely overcame this mentality and proved herself to be a great singer.
- Kyoka's favourite thing is rock, evident by her hero costume and love for music.
- Kyoka's Quirk was inspired when Horikoshi wanted to make a character who could plug their ears into objects while he was listening to music on a trip back home. Her Quirk may have actually been the first that Horikoshi came up with.
