kyouka jiro

The Punk Rocker of Class 1-A

Beneath her reserved demeanor, Jiro is a massive fan of rock and roll. Raised by parents who also love music, she owns multiple instruments and uses music as her primary form of expression. Despite being exceptionally talented musically, she initially felt a bit embarrassed by her hobby, believing it was entirely unrelated to being a hero. However, her musical gifts ultimately became her defining contribution to her class, most notably when she led the U.A. School Festival performance. [1, 2, 3, 4]

Sarcastic, Teasing, and Protective

Jiro is known for her blunt, snarky comments, which she frequently directs at her clutzy and clueless classmate, Denki Kaminari. She isn’t afraid of a little aggressive physical discipline either, often using her Earphone Jack quirk to keep boys like Kaminari and Minoru Mineta in line when they get out of hand. Despite her sharp tongue, she is deeply empathetic and loyal. She has a particularly soft spot for her close friend, Momo Yaoyorozu, acting as her staunch defender and biggest supporter. [1, 2, 3]

Surprising Insecurities

Unlike some of her more boisterous classmates, Jiro is surprisingly self-conscious. She struggles with certain body-image insecurities, worrying she isn't as physically developed as the other girls in her class. She also has a strong aversion to nudity and a hilarious, paralyzing fear of horror-based activities. [1, 2, 3, 4]

Pragmatic and Humble Heroism

When it comes to hero work, Jiro transitions from a slacker-styled teen to a highly intelligent strategist. She prefers smart, tactical approaches over brute force, and her quirk allows her to excel at stealth and reconnaissance. She is notably humble and pure-hearted, pursuing heroism purely out of a genuine desire to help society rather than using her U.A. High training as a stepping stone to a celebrity music career.

Traits

Counter-Balance (カウンターバランス, Kauntābaransu?): Plugging her jacks on the legs of her hero costume, Kyoka sends out a powerful soundwave from the amplifiers on her legs that cancels other sound-based attacks

Heartbeat Distortion (ハートビートファズ, Hātobīto Fazu?): Plugging her jacks on the special sound amplifiers on her forearms, Kyoka slams the amplifiers onto the floor and channels a powerful soundwave, shattering the ground due to the vibrations.[14]

Heartbeat Surround (ハートビートサラウンド, Hātobīto Saraundo?): Plugging her jacks on the special sound amplifiers on her forearms, Kyoka uses her elongated earlobes to remove the amplifiers from her wrists and direct them towards her target at close range, releasing a powerful, short-range soundwave to incapacitate them.[15]

Legato (レガート, Regāto?): Kyoka performs her Heartbeat Surround move on a larger scale, with more power, and with more sound generated.[16]

Heartbeat Wall (心音ハートビート壁ウォール, Hātobīto Wōru?): Similar to Heartbeat Surround, Kyoka once again plugs her jacks on her forearm amplifiers and uses her earlobes to remove them and aim them towards a target, but instead channels her heartbeat to form a sound wall that blocks and impedes her enemies' movement

Personality

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.

Earphone Jack (イヤホンジャック, Iyahon Jakku?): Earphone Jack's eponymous Quirk is that she has a pair of headphone jacks hanging from her earlobes. When the jacks are plugged into something, Kyoka can channel the sound of her heartbeat through them in the form of a violent vibration attack. She can stretch her earlobes several meters. This Quirk also allows her to hear minuscule sounds and vibrations from her surroundings.

As part of her training, Kyoka honed her headphone jacks by repeatedly piercing them into a stone cliff, all to increase the amount of audio she can hear with her Quirk

Keen Intellect: Despite her unenthusiastic demeanor, Kyoka is quite intelligent, scoring 7th place in the midterms, displaying her skill in academics. She is also quite strategic, as she took advantage of the volatile nature of Denki's Quirk to allow the Stun Gun Hero to electrocute multiple villains during the U.S.J. Incident.

Indomitable Will: In a rare sense of moment, Kyoka displays remarkable willpower. Though not as strong as All For One, Tomura, or Izuku, she managed to shrug off her fear after feeling the overwhelming power of All For One during the Final War. Her spirit was strong enough to stir up resistance from within All For One's vestige world, causing some of the former users of the Quirks he has stolen to rebel against him, although All For One also surmised that this was due to him using a duplicate of his Quirk rather than the original.

Musical Talent: Kyoka is able to play the bass, which is her preferred instrument alongside the guitar. She can play other instruments as well, like drums, but only to a limited extent. Her singing voice is described as "husky, but heavenly".
