Kyoka Jiro/Synopsis

History
Kyoka was born to Kyotoku and Mika Jiro, a couple of a composer and a musician. She inherited her mother's Quirk, Earphone Jack.

At a young age, thanks to the influence of her parents, Kyoka developed an interest in music, eventually learning to play several instruments.

Despite her parents desires for her to become a musician, she decided to become a hero instead because she wanted to dedicate her work to others. When she told her parents about her plans, they were happy for her and let her walk her own path.

Battle Trial Arc
She is teamed with Denki Kaminari as "Team G" after being randomly drawn, participating as the Hero team. Kyoka uses her Earphone Jack to locate the rival team, indicating it to Denki, who advances with his Quirk ready to be used. It is unknown how well they both did in the trial itself.

U.S.J. Arc
When actual villains invade, Kyoka is warped to the mountain area of the Unforeseen Simulation Joint along with Momo Yaoyorozu and Denki. Annoyed that Denki is complaining too much, she kicks him into one of the villains, causing the villain to be electrocuted by Denki's Electrification. She then uses her Quirk to protect Denki from an attack by one of the villains.

Kyoka plugs her jacks into her boots to launch a sonic attack, causing the villains to block their ears in pain, which gives Momo the time needed to create an insulator sheet. Kyoka and Momo hide under the insulator sheet while Denki discharges a great amount of electricity, defeating the villains while Kyoka and Momo remain unharmed.

However, one of the villains takes the air-headed Denki hostage, forcing Kyoka and Momo to stop fighting back and remain motionless. Kyoka attempts a sneak attack by distracting the villain through conversation, but fails.

Fortunately, the villain holding Denki is shot down by Snipe, freeing Denki, with Kyoka rushing to tie up the villain. She is then seen with her class after the battle with the League of Villains is over.

U.A. Sports Festival Arc
After Shota Aizawa announces that the U.A. Sports Festival is approaching, Denki says that he plans to become a Pro's sidekick after he graduates, to which Kyoka states that many people become sidekicks and fail to become real Heroes, to which she thinks that Denki is the kind of person who would become like that, which causes Denki to become crestfallen. Kyoka competes in the Obstacle Race where she places twenty-first, allowing her to compete in the Cavalry Battle.

In the Human Cavalry Battle, she teams up with Rikido Sato, Koji Koda, and Toru Hagakure while Toru is the rider. When the Human Cavalry Battle begins, Kyoka uses her Quirk to try and grab Izuku Midoriya's headband like Tetsutetsu Tetsutetsu told her, but Fumikage uses his Dark Shadow to block her attack. Later in the Human Cavalry Battle, her team charges towards Shoto Todoroki's team, but her team gets zapped by Denki and frozen by Shoto's team. Her team fails to qualify to the next round when her team lost the Human Cavalry Battle.

After Denki and Minoru Mineta states that the girls must do the cheering battle as per orders from their homeroom teacher, Kyoka and the other girls of Class 1-A walk out in cheer leading outfits. However, as Kyoka and the girls walk out, they realize they have been tricked. Kyoka then calls Denki and Minoru idiots. During the recreational events, Kyoka is seen sitting still in her cheerleader outfit while watching Mina Ashido, Ochaco Uraraka, Tsuyu Asui, and Toru cheer-lead.

As the match between Ochaco and Katsuki begins, Kyoka comments that she might look away the entire time. During the match between Ochaco and Katsuki, Kyoka averts her eyes from the match when seeing Katsuki's explosion assault on Ochaco.

Kyoka along with her class watches the closing ceremony of U.A.'s Sports Festival.

Vs. Hero Killer Arc
Two days after the Sports Festival, Kyoka is in class. During the Hero Informatics period, Class 1-A has to decide on Hero names. Kyoka gives Denki an idea for his Hero name: Jamming Way, causing Denki to reply that her idea was good, as it references the intellectual: Hemingway. But Kyoka revealed she was just using that name as a means to make fun of Denki, leaving him disappointed. Kyoka writes down and shows her Hero name to her classmates. Kyoka reveals her Hero name to be Earphone Jack, the Hearing Hero.

After Class 1-A has finished formulating their hero names, Kyoka is given a list of 40 workplaces in order to choose a workplace that she would like to train at. On the day of the workplace training, Kyoka is at the train station with her class so that she can go to the workplace of her choice by train.

Kyoka chose Death Arms for her Hero Agency Internships. Death Arms works out Kyoka hard in the field. He makes her run during patrol and she barely keeps up with him. Kyoka thinks to herself about much harder her training is compared to school. Later, Kyoka helps Death Arms rescue civilians from a hostage situation. She uses her Quirk to figure out how many hostages were taken. Kyoka escorts them both to safety after Death Arms rushes in.

The workplace training comes to an end and Kyoka returns to U.A. After Foundational Hero Studies is finished, Kyoka catches up with Tsuyu and Mina and she is amazed by Tsuyu's activities. She is among the students bearing witness to the gamma race, where she and Momo count Izuku out since his Quirk has repercussions. They are quickly proven wrong when Izuku shows off his new moves and they are surprised as well as amazed at his better control of his Quirk and lead in the race until he trips causing him to lose.

Later on, Kyoka is in the girls' locker room where she uses her earphone jacks to hear Minoru's plan to peek on the girls. Kyoka plugs one of her earphone jacks into the hole which stabs Minoru's eye, stopping Minoru from peeking. Though thanked by the other girls, an embarrassed and insecure Kyoka wonders why she was the only one he did not mention.

Final Exams Arc
One week before the end of term test, Kyoka asks Momo to help her study. Throughout the final week before the end of term test, Kyoka studies under Momo's tutoring along with Denki, Mina, Mashirao and Hanta. On the day of the exercise test, Mr. Principal reveals that Class 1-A will be fighting against U.A.'s teachers for their First Term Final Exam. Kyoka is paired with Koji and they must face Present Mic in their exam.

Koji, Kyoka and Present Mic arrive in an uninhabited city where Class 1-A's test exercise will take place. In the city, Kyoka mocks Present Mic for what she takes as a poor reference, to which Present Mic tells her to be careful with what she says. Present Mic explains the 30-minute test; Kyoka and Koji must either handcuff him or one of them must escape the battlefield within 30 minutes in order to win and pass the test. The test begins.

Kyoka plugs in her Earphone Jacks to try and block out Present Mic's loud voice, but to no avail. Annoyed by Present Mic's loud voice, Kyoka tells Koji to command the nearby animals to attack but Koji is unable to due to Present Mic's voice making the animals wild and as a result, any command he gave would be useless.

Kyoka and Koji manage to get a little closer to the escape gate, but Kyoka notes that Present Mic will be at the escape gate and that no matter what option of victory they choose, a standoff is inevitable. Present Mic uses his loud voice again; Kyoka notes that they cannot get any closer as long as Present Mic is using his Quirk. Kyoka sees an ant and comes up with an idea; she asks Koji if he can control bugs but his terrified reaction indicates that he doesn't like bugs. Present Mic uses his loud voice once again; Kyoka tries to counteract with her Earphone Jacks and use Counter-Balance on Present Mic's voice.

Present Mic continues using his loud voice against Kyoka and Koji who are unable to handle it. Out of options, Kyoka asks Koji if he can control insects to which he approves. Kyoka uses her Earphone Jacks to break a rock which reveals dozens of insects, much to Koji's terror. Kyoka tells Koji that she understands his phobia but using the insects to attack Present Mic is the only plan she can think of because their opponent is too strong. Kyoka encourages Koji to follow through with her plan.

After seeing Kyoka's bleeding ears, Koji is ashamed that he is running away from this fight and realizes that he can only continue being at U.A. by overcoming his fear. Koji musters up the courage and commands the insects to attack Present Mic while Kyoka is annoyed he picked that moment to talk. At the escape gate, Present Mic sees that time is nearly up. Suddenly, dozens of insects crawl on Present Mic, who realizes that the insects traveled to him by moving underground; a place where sound is ineffective. Present Mic is paralyzed by fear, allowing Koji to run through the escape gate while carrying an injured Kyoka with him; thus they pass the practical test.

Back at U.A. in class, Kyoka learns that she has passed the written test and will go along with her classmates to the forest lodge which is a boot camp. Kyoka accompanies her class to the Kiyashi Ward Shopping Mall to buy necessities for the forest lodge. At the shopping mall, Kyoka says that she requires a big carrying bag, to which Momo tells Kyoka that she will help her look for it.

My Hero Academia: Two Heroes
After Momo was invited to I-Expo she had a few extra invitations, so her, Kyoka, Tsuyu, Mina, and Toru played Rock, Paper, Scissors to see who would go to the preview of I-Expo. Both her and Ochaco won their chance to see the preview.

While looking around the expo, she, Momo, and Ochaco see Izuku talking with Melissa Shield, and suspect that they are on a date. Izuku clears up the misunderstanding and says that Melissa is showing him around the expo. The five go get tea at a café, and are surprised to see Denki Kaminari and Minoru Mineta, who are working as extra staff at the cafe. They soon meet Tenya, who is representing his family, reprimanding Denki and Minoru for slacking off.

They notice an explosion nearby, and the group finds out about the Villain Attack attraction, where they see Eijiro and Katsuki. Katsuki notices Izuku and is irritated, making a scene in front of the audience. Melissa watches in amazement at the young heroes around her, while Kyoka, Momo, and Ochaco express embarrassment at Katsuki's crude behavior.

Melissa invites the students to attend the reception party at 6:30 PM, and Momo helps choose formal clothes for Kyoka and Ochaco. The students are stunned at their formal clothes, embarrassing Kyoka and Ochaco. However, the I-Island Security System sets off an alarm across the whole island, locking the central tower from the outside. Because their cell phones have no signal and the elevators are disabled, Izuku tells everyone to head over to the party because that's where All Might is.

With the help of Kyoka's Earphone Jack Quirk, they learn that the villain Wolfram has the island held hostage. Tenya suggests that the students escape since they can't legally fight villains, but Melissa reveals that I-Island's security is on par with Tartarus'. Shoto and Kyoka believe that they should try to help while Minoru and Momo believe they can't. Awkward silence is interrupted when Izuku says he wants to save everyone. After discussing among themselves, everyone agrees to try to help the heroes by disabling the security system.

They scale over fifty floors before being blocked by a closed shutter on the 80th floor. Minoru accidentally opens the door to the main section of the floor, notifying the villains. Before the shutters could close them off from both ends, Tenya and Shoto make an opening and lead the group into the plant factory. Kyoka notices the elevator coming up, so they hide. The villains in the elevator notice and attack Katsuki and Eijiro, who were lost. Shoto saves them and lifts the rest of the group up using an ice pillar.

The group find a small roof panel that leads to the maintenance room, and convince Minoru to complete the job. He succeeds, and the group advances past the 100th floor. They notice that the shutters are closed and deduce that the villains are trying to lead them somewhere, which turns out to be a swarm of security bots on the 130th floor. Denki attacks first with his Indiscriminate Shock 1.3 Million Volts, it turns out ineffective against the robots, so they resort to using Momo's smoke bombs. Izuku and Tenya use their power to break through the robot blockade. Tenya rescues the short-circuited Denki while Kyoka listens for more robots.

In the server room on the 138th floor, the group agrees to stay back and fight the incoming security bots while Izuku, Melissa, and Ochaco continue up. Tenya uses his Recipro Burst and Momo creates a cannon that fires adhesive material. However, Tenya, Minoru, and Momo pushed themselves to their limits, so they are restrained by the robots. They are set free when Melissa overrode the security system, and they head to the top of the tower. There, they encourage All Might and Izuku as they fight Wolfram, and cheered after his defeat. Kyoka is later seen hanging out with her classmates at a barbeque party.

They will face Class B's team of Yosetsu Awase, Kojiro Bondo and Togaru Kamakiri and leading by Setsuna Tokage at Round 4.

Katsuki wants to take the lead and charge ahead with the others serving as back up. He tells Kyoka to pick up on the sounds coming from the Class 1-B team and to figure out their location. Class 1-A charges through Ground Gamma towards the enemy. Katsuki yells at his teammates saying that they are too slow. Kyoka says that she is trying to listen to the sounds as she goes to which Katsuki says to forget about it and to just hurry up and follow him.

Katsuki notices someone up ahead and tells Kyoka to use her Quirk hurry and find their location. She proceeds to do so and notices there are dozens of sounds that lead them into a trap. She tries to warn her team but it's too late. Setsuna's detached mouth sneaks up behind Katsuki and confirms the ambush. Setsuna's Lizard Tail Splitter lets her spread out her separated limbs throughout the field and uses her tiny body parts to attack. Katsuki gets bombarded by Setsuna's Quirk.

Hanta uses Barricade Tape to protect his team, so that the lizard parts cannot attack and proceeds to call Katsuki over. Setsuna tells Kojiro it's his turn and he uses Glue Squall spread his adhesive all over Hanta's tape barricade. Togaru watches the Class 1-A team struggle and uses his Quirk to slash a large pipe that crashes down toward the other team. Rikido prepares to sacrifice himself and catch the falling pipe but Katsuki manages to fire a large enough explosion that destroys the glue covered pipes and barricade.

With the barricade gone, Togaru believes Katsuki's actions destroyed his team's protective shelter and dives towards the Class 1-A team to attack them. Setsuna orders him to take out Kyoka first because her Quirk is the most troublesome. Just as Togaru is about to land a fatal blow, Katsuki appears and kicks Kyoka away, hitting Togaru him with a powerful explosion at point-blank range.

Class 1-B members are surprised with the behavior of Katsuki, causing they plan to fail, leaving them totally unprepared. Kyoka tries to hone in on Class 1-B but Setsuna's interference makes it difficult. She does notice that there are fewer sounds than before and Class 1-B is retreating. Katsuki surmises they're trying to regroup. He is not willing to allow it and chase them.

Yosetsu traps Katsuki with his Construction-Done-Kwik: Weldcraft, but Rikido acts quickly and frees Katsuki from his restraints. Katsuki flies at Yosetsu, who then tries to protect himself by attaching multiple steel plates to his body. It turns out that Katsuki was merely tricking him by blasting upwards and lets his teammates take out the enemy. Hanta carries Kyoka to the fight and she attacks Yosetsu with Heartbeat Surround, stunning him. Then, Hanta wraps up Yosetsu. Kyoka then directs Katsuki towards the remaining members of 1-B. One by one the members of the class 1-B team are defeated and captured by Class 1-A, with little to do to counterattack or defend themselves.

After Eijiro, Katsuki and Denki saved Yuga, Minoru and Toru from the villain Mummy, the girls bring them to safety as well as direct the citizens to the safe hold. When Mummy is defeated, Kyoka and Momo arrive to inform their classmates that they have already evacuated all the citizens of the area. Katsuki tells them to continue the evacuations as he heads off to find more villains.

However, Class 1-A fails to defeat the remaining villains, and they are forced to retreat. At night, the Class A members regroup at a factory where the rest of the island citizens are currently staying at due to the villain attack. The students provide them first aid, supplies and meals. Kyoka shows concern for Denki and Momo for using their Quirks to the limit to create a large a mount of supplies for the refugees.

Later, all the students have a meeting where they discover that the objective of the villain leader, Nine, is to steal the Cell Activation Quirk from Katsuma. With this information, they devise a plan to approach them in front and keep civilians safe. The plan is to lure the villains to the furthest corner of the island where ancient castle ruins are. The heroes will engage the villains using the terrain to their advantage and spit the villains apart, so each member has to face several students alone. After his previous fight against Nine, Izuku concludes that Nine cannot use his multiple Quirks for too long as he suffers from intense pain when he does. To deal with Nine, everyone will attacks him in waves to force Nine to use his Quirks all the time until he reaches his limit and cannot continue fighting. Kyoka, Mashirao and Mezo are in charge of guarding Katsuma and her sister Mahoro while the remaining students face the villains.

The next morning, Nine and his gang arrive at the entrance to the island. They fall into Class 1-A's trap and are forced to split up by Yuga and Momo's Ultimate Moves; and following Izuku's plan, the students take turns attacking Nine to force him to use his Quirks as much as possible. The students are on the verge of winning when, in his despair, Nine injects himself a high dose of Quirk's enhancer drug and defeats everyone.

The situation for Class 1-A is growing desperate. Kyoka and Mashirao tell Mezo to take the kids away while they hold off against Nine. They ambush the villain in a bridge, which they destroy by using Kyokya's Heartbeat Distortion and Mashirao's Tornado Tail Dance. Nine falls into the fissure but he quickly summons his sinuous dragon to escape, smashing Kyoka and Mashirao in the process. Mezo is about to escape with the children when he is attacked by Nine. The injured Mashirao and Kyoka catch them up and attack Nine with Mezo tackling, but the villain uses his Air Wall Quirk to blast all three of them away, defeating them.

Nine is in pain by dealing with the constant attacks from Class 1-A members, but his prize is finally now at his fingertips. Fortunately, Izuku and Katsuki arrive in time to confront him. While Kyoka is unconscious, Izuku and Katsuki manage to defeat Nine, saving the island and its inhabitants in the process. After Class 1-A emerged victorious over the threat, the military and a large number of heroes arrive on Nabu Island, rescuing the civilians and medically treating Class 1-A. The villains are arrested, and Class 1-A continues to stay on Nabu Island to help repair the damage done by Nine and his villains until the Public Safety Commission suspends the program and orders them to be sent home.

With the island being repaired by the military and the heroes, Class 1-A boards a ferry to return to the U.A. High School.

Paranormal Liberation War Arc
Winter break is over, and so is Hero Work-Studies. The students return to the U.A. to continue their studies and show their progress. Kyoka Jiro and Mezo Shoji, who worked with Gang Orca, show off their enhanced search techniques. Later at night, Kyoka helps her classmates to organize a Work-Study/Brainstorm/Hot pot party to energize everyone for the new term.

The months go by until it's late March. The Hero Public Safety Commission had uncovered the plans of Tomura Shigaraki and his organization, the Paranormal Liberation Front. They organize a large force of heroes to take the villain organization down. While a team of heroes raid the Jaku General Hospital, where the Nomu are created, another team does the same at Gunga Mountain Villa, the Front's main headquarters. Kyoka is a member of the Villa Backup Team along with many of her classmates and Class 1-B students. Their mission is to provide support to the heroes who raid the Gunga Mountain Villa and prevent villains from escaping.

Using her Quirk, Kyoka learns that the enemy is on the move and the heroes tell everyone that while this operation has brought Heroes together on an unprecedented scale, it is no reason to relax because they need everyone present to help with the massive threat they are about to face. Kyoka remarks that she isn't too worried about Fumikage, but is more concerned for Denki, though Momo reassures her that he will be fine. Kyoka then hopes for a panicking Denki to complete the mission quickly and safely.

After the raid commenced, heroes gained the upper hand, taking down many of the Front's members. However, the Jaku team allowed Tomura to awaken and he ordered Gigantomachia to come to him. This results in the giant defeating many heroes as he simply walked towards Jaku City.

Kyoka is shocked to suddenly hear something big incoming, and informs her teammates about it. Shortly after, Midnight contacts Momo after failing to stop Gigantomachia. She orders her to use sedatives to put the hulking beast to sleep before losing contact. Momo comes up with a plan and orders Kyoka and Mezo to use their quirks to determine the time it will take Gigantomachia to arrive at their location and the path he will use. Kyoka informs that Gigantomachia will not be long to arrive, when she and Mezo notice that Mt. Lady and Kamui Woods both holding on to Gigantomachia's leg, slow him down just a little bit.

This gives students enough time to set up a trap. Momo uses her Quirk to create a large number of vials of undiluted sedative, giving each student a vial. The plan is to try to get Gigantomachia to swallow at least a sedative to put him to sleep. Following her lead, Juzo uses his Quirk to soften up the ground and Momo creates explosives with her Quirk and plant them in the softened areas. They also position several chords covered in Minoru's orbs. As they planned, Gigantomachia step into the students' trap and he falls to the ground. The strings covered in Minoru's orbs stick to his chin, and while the giant tries to get out, several students pull the strings to force him open his mouth, while the others charge at him to give him the sedative. Meanwhile, Kyoka and other students attack the PLF lieutenants that Gigantomachia carries on his back to prevent them from intervening. Kyoka tries to sneak attack them with her Amplifier Jack, but Dabi notices her and blasts her jack with his flames, causing her to retract it.

The PLF lieutenants and Gigantomachia manage to repel the initial assault, and Dabi creates a fire barrier to prevent the students from getting close, but several heroes arrive to help them, and Eijiro Kirishima finally manages to throw a vial into Gigantomachia's mouth. After creating fireproof suits, Momo drives Kyoka and other students away from the flames. Momo says that now that Gigantomachia has ingested the sedative, they need to make him move around so it will spread faster. She calls out to Majestic and he flies in with several other Pro Heroes to take him on.

Annoyed by the constant interruptions, Gigantomachia, takes on an armored appearance and easily kill any heroes, and continues on his way to Tomura. Before being killed, Majestic uses his Quirk to bring the U.A. students to safety, who can only watch helplessly as the giant devastates everything in his path.

Kyoka is then seen informing Tenya that Fumikage and Denki have been discharged and are ready for release, -as she was also wondering what was going on with Katsuki still yelling and complaining. Furthermore, Kyoka asks if Izuku is doing alright, with Ochaco responding that she is feeling worried. As Best Jeanist and Hawks enter to talk about One for All with All Might, Kyoka, alongside Tenya and Ochako go into Izuku's room to check on their friend.

Later, after the Paranormal Liberation War ended, Kyoka and the rest of Class 1-A received a letter from Izuku explaining the history of him being Quirkless and OFA, making him leave to avoid them being targets by AFO.

Tartarus Escapees Arc
A few days after Izuku left U.A., Kyoka joins a meeting with Class 1-A. He and Class 1-A deduce that Izuku is now working with Endeavor and his team. Kyoka says that All Might hasn’t returned either and Mashirao adds that classes have been suspended and they haven't become second years yet, with the Hero course students on standby and helping as security, so acquiring any information in this environment will be tough. Yuga says that if that is true, then their worries should be alleviated and Denki replies that the media reported only the top three heroes are working together, so All Might can’t be involved, meaning that Izuku and All Might are working together. Eijiro wonders how will they get to contact the heroes who possibly know the whereabouts of Izuku, and Ochaco suggests to push their issue forward. A few days later, impatient with their response, Class 1-A pushed forward using Endeavor's U.A. Alumni status to confront him despite knowing how much he does not like to be tricked.

Once Principal Nezu gives Class 1-A permission to bring back Mizuku to U.A, Kyoka joins with Class 1-A to search for Izuku while at the same time, apprehending any prison escapees along the way. After months of trailing in Izuku's whereabouts, Class 1-A finally arrived on the scene to defeat Dictator. When Izuku refuses to yield, he demands everyone to get out of his way, which means they might have to fight Deku.

Kyoka attacks Izuku using her Amplifier Jacks to erect a barrier of sound waves called Heartbeat Wall, forcing him to jump away. She reminds Izuku the time he helped her to organize her notes ahead of the School Festival before falling over as Rikido catches her.

She links up with the rest of the class after Tenya and Eijiro catches Izuku. She listens to Katsuki apologizing to Izuku before he collapses from the shock and exhaustion. Once Izuku was secured, she escorts him back to a heavily fortified U.A High where Class 1-A is confronted by angry protesting civilians.

As Class 1-A returns to their dormitory building and rests, Kyoka is seen in the living room with the rest of her classmates, listening to them about their current situation. She then points out how none of the evacuees UA is taking care of seems to be happy about the efforts the heroes are doing, to which Kyoka begins to link with what happened before. With her Earphone Jacks, she drags in Fumikage, Yaoyorozu, and Kaminari to her side. Todoroki asks where she's getting at as she recalls Class 1-A's moment during the School Festival, where there were certain people among the audience who we're not happy about their status. Kyoka then tugs on Bakugo's shirt's back-piping and pulls him to join her and their band-mates in the scene. She completes her statement, suggesting an idea on how to relieve and make people smile again as she points back to when they performed for UA and how it was successful. Kyoka smiles, stating how they'll work to make the world a better place, by doing it together until the end.
