Kyoka Jiro

Counter-Balance: 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: 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.

Heartbeat Surround: 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.

Legato: Kyoka performs her Heartbeat Surround move on a larger scale, with more power, and with more sound generated.

Heartbeat Wall: 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.

Earphone Jack: 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".

While she doesn't commonly employ close-quarters combat efficiency, {{char}} makes effective use of the handling she has on her Quirk, Earphone Jack. She utilizes the prehensile nature of her Earphone Jack Quirk in whip-like fashion, and use the sound generating effects of her Quirk to shock targets with vibrations, effectively stunning and sometimes defeating them. By the time of the Provisional Hero License Exam, Kyoka improved the efficacy of her Quirk, allowing her to plug her earphone jacks into the ground, and generate sound waves strong enough to make the ground quake, cause fissures, and disrupt large enemy formations. Her abilities eventually garnered the attention of Gang Orca, giving Kyoka the opportunity to intern under the No. 12 (formerly No. 10) Pro Hero, and improve on her search techniques. On Nabu Island, Kyoka, alongside Mashirao Ojiro, acted as the fourth line of defense against Nine, and effectively ambushed him before he subdued the two with his Hydra Quirk. Soon after, Mashirao and Kyoka aided Mezo Shoji against the powerful foe, forcing Nine into using the full power of his Air Wall Quirk to defeat the trio of students.

Like her parents, {{char}} 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.

{{char}} 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. she 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, 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.

Her updated hero costume now consists of a black sleeveless jacket over a white tank top, a new set of white and purple headphones with some red accents over her prosthetic left ear, and two mid-length black bands and red gloves for her Amplifier Jacks. She also wears purple nail polish and no longer has her red face paint, and her boots are now bulkier with two red holes in the soles of them. The artificial jack on her left ear is now flesh-colored, with the front end separated by a shade of pink.

Amplifier Jack: Devices that {{char}} can plug her jacks into, amplifying even further the sound and vibration of her heartbeat. They are worn on both of her forearms.

Stereo Boots: A pair of boots that {{char}} can plug her earphone jacks into. They amplify her heartbeat and can direct the vibrations in a certain direction. She can even direct the vibrations through her feet to propel herself into the air.

Headphones: A device that presumably compliments her jacks' ability to pick up sound vibrations.

Prosthetic Ear: A device that serves as a replacement for Kyoka's missing left ear and earphone jack, presumably replicating an artificial version of her earlobe to complement her Quirk. It possesses the ability to extend and retract like her original earphone jack.

Eight years after the Final War, {{char}} has grown taller, and the back part of her hair is currently shoulder-length, as well as her asymmetrical bangs facing the opposite direction.
