Kazuho Haneyama/Synopsis

History
As a child, Kazuho one day asked her mother who the people on TV were, to which her mother replied that they were celebrities who were either Heroes or performers. Newly inspired to one day appear on TV herself, Kazuho wondered aloud which profession would be easier, and her mother replied that she didn't know but that Kazuho should go down the path she likes the best, either a Hero who saves people when they're in trouble or a performer who sings and dances to make people happy. Kazuho smiled and said that she wanted to be a performer.

Later, Kazuho began acting as an idol at a young age, performing shows on the streets of Naruhata, and in time she would become popular with the locals.

Sometime after, on a rainy day, Kazuho tried to leap across a river but slipped on the soaked ground and fell into the water. On his way to take his hero-course entrance exam, a young Koichi saw her (though he thinks she's a boy), jumped into the river and pulled her out of the water and gave her his silver age All Might hoodie.

At that time she did not know his name but she was intrigued by him from that day forward, until several years later when she finds Koichi again. Kazuho always wanted to give him back his hoodie and thank him properly, although she still doesn't have enough courage to do it.

Vigilantes Beginnings Arc
Several years later, Kazuho reencounter Koichi while performing his street performances as Pop☆Step. Koichi notes that Pop☆Step is taking a big risk in being a freelance idol since she does not have a permit. A police vehicle is passing by, so Koichi warns Pop☆Step, who decides to end her live performance and flies away.

Later that night, while Koichi was returning home after an incident at work, he meets Kazuho again in an alley. She thanks him for helping her that morning but she make fun of him for being weak and wearing an All Might hoodie, which causes both to start arguing. Pop☆Step begins to leave but bumps into Soga Kugisaki and his friends Rapt and Moyuru. The thugs recognize her as the online idol, begin mocking her and even thinking to sexually assault her.

Scared, at first Koichi thinks about leaving her to her fate, but seeing her scared face decides to help her without thinking. He does not have much success at first, and all he gets is to anger even more Soga, but with the sudden appearance of Knuckleduster, between both defeat the thugs and save Kazuho. After this incident, Knuckleduster decides to adopt Koichi as a pupil despite his refusal.

The next day, Kazuho meets Koichi and Knuckleduster again, the latter causing trouble on the streets and attacking people for no apparent reason. Koichi explains to Kazuho the situation, KD's mission is to dismantle the illegal traffic of a drug known as Trigger, which boosts an individual's Quirk and turns him into a violent villain. The only way to identify drug users is through the tongue, which turns black from the trigger. The problem is that Knuckleduster is not very subtle in his methods to extract information and Koichi is only there to prevent Knuckleduster from punching anyone he considers suspicious.

Pop thinks that they should use their heads instead of violence, and suggests that they should search on the internet for "sudden villain appearances" which will allow them to pinpoint the location of the Trigger Junkies making it easier and more productive to find potential Trigger users.

In that moment Knuckleduster spots Mario Kugutsu, a salesman who looks suspicious to him, and tries to interrogate him by force. Koichi and Kazuho try to stop him to avoid more problems, but at that moment Shota Aizawa appears, and stop Knuckleduster under the suspicion of being a villain, which causes a fight between the two, much to Koichi and Kazuho's horror.

The salesman leaves in a hurry, but after seeing some images on the internet related to recent villain incidents, Kazuho realizes that Mario is really a suspicious person, so she and Koichi chase him. Unfortunately, they meet again with Soga, Rapt, and Moyuru. Mario had supplied them with Trigger, so transformed into Instant Villains, they attack Koichi and Kazuho.

As Koichi escapes from Soga and Moyuru, being saved by Knuckleduster and Shota, Kazuho is chasing after Mario while Rapt is right on her tail. Mario finally decides to inject Trigger himself, transforming into a giant four-armed being, catching Kazuho and Rapt and playing with them as if he were a child. Fortunately, Koichi manages to rescue her and Knuckleduster and Shota defeat Mario, who is arrested by the police along with Soga and his friends.

Kazuho personally thanks Koichi for risking his life to save her. KD also praises the courage of Kocihi, who finally accepts his offer to be his student, and the three decide to form a team of vigilantes dedicated to protect Naruhata.

Soon the trio begins to patrol the streets. In their first of them, Kazuho sees two middle schoolers (Ichimoku Samazu and Jube Namimaru) fighting, and aks her teammates to intervene and stop the fight, but Koichi fails since neither Ichimoku and Jube takes his new "The Crawler" persona too seriously, and Knuckleduster has to be stopped since he prefers to use violence. Annoyed that it is taking too long for them to stop the fight, Pop☆Step arrives and uses her appeal to stop the middle schoolers' fight, which works since both Ichimoku and Jube are fans of her.

As Kazuho is about to give them her autograph, an Instant Villain called Akira Iwako starts attacking innocent civilians with his Trigger-enhanced abilities. Koichi and Knuckleduster manage to defeat Akira, and Kazuho informs the middle schoolers about the Trigger drug. When they hear police sirens, Koichi and Knuckleduster scram and Kazuho leaps away and tells Ichimoku and Jube that she will see them next time.

A few days later, both Kazuho and Knuckleduster, dressed in civilian clothes, appear at Koichi's penthouse, which since then will be used as the "headquarter" of the team. After putting on her Pop☆Step outfit at Koichi's home, Kazuho heads to gives her street performance to her fans.

One of them, Teruo Unagisawa, is desperate to get closer to Pop☆Step, but other fans shoves him all the way back, so he injects Trigger into his neck, causing him to transform into a Eel-like Instant Villain, and begins to chase Kazuho through the alleys of Naruhata. Fortunately, Koichi and Knuckleduster help her, setting a trap for Teruo, who is defeated and arrested soon after by the police.

The following day, after being interrogated by the police, Teruo is released without charge as he only caused minor damages. Jube and Ichimoku see Teruo and send a message to Kazuho, who is at Koichi's house. Kazuho tells Koichi that they can meet up with them and talk with Teruo in order to get some information about the person who gave him Trigger.

On their way, they encounter a fan who recognizes Kazuho and takes a picture with her. Koichi and Kazuho meet up with Ichimoku who tells them that Jube is with Teruo, and they will arrive soon. Unfortunately, Knuckleduster is there as well, and both Kazuho and Koichi fear that he will use violence to interrogate Teruo.

Meanwhile, the fan that took a picture with Kazuho is actually a villain known as Kuin Hachisuka. She works for the villain organization responsible of the trigger drug trafficking, and she is responsible for many of the Trigger related incidents in Naruhata.

Kuin uses her Queen Bee Quirk to release a swarm of bees filled with Trigger, and injects the drug into a large number of innocent civilians, transforming them into Instant Villains. This causes many heroes to intervene and suppress the villain outbreak. During the chaos and confusion, Teruo separates from Jube, meeting Kuin shortly after, who convinces him to accompany her. Jube later meets Kazuho and the others, apologizing for losing track of Teruo. After this, Kazuho continues to help his teammates in the fight against trigger traffic.

One day, she arrives at Koichi's penthouse while Koichi himself is busy fixing his All Might hoodie. After grabbing a pudding, Kazuho wonders why Koichi does not replace it with something new. Koichi refuses to since it is official All Might merch. Koichi tells Kazuho that he was planning eating the pudding, which makes her blush and causes her to blame him for not labelling the pudding. Koichi doesn't mind and says that he will buy more, also tells Kazuho that she is not one of those who asks for apologize easily. Kazuho is annoyed by that remark, and replies he spends a lot of time on his lame All Might hoodie. Koichi snaps at her because he refuses to allow anyone to insult his collection, showing he has every limited edition except for the silver age one.

When Kazuho asks him what happened to it, Koichi replies that five years ago, while on his way to a hero-course entrance exam, he gave it to a boy whom he rescued from a river. However that incident made him late for his exam, losing his chance to become a pro hero. Koichi hopes that the child he saved grows up to be a Hero who was inspired by being saved by his heroics, and hopes that his ideals reach him through the hoodie he gave him. Unimpressed at Koichi for messing up his Hero career so that he could rescue some nameless child, Kazuho goes home in a bad mood.

At home, Kazuho takes out the limited edition silver age All Might hoodie, revealing that she was the "boy" Koichi saved on the day of his examination, causing her to blush. She always wanted to give it back to him but she never dared. Determined to overcome her fears, Kazuho decides to return the penthouse and give the hoodie to him back and thank him as well as apologize for causing him to miss the exam. On the way, she also buys pudding for both of them.

Kazuho returns to the penthouse, but Knuckleduster's presence ruins her opportunity to tell Koichi the true. Kazuo and Knuckleduster eats the pudding while Koichi asks Kazuho what she wanted to talk about. Annoyed at the inconvenience, she once again goes back home. In her home, Kazuho puts on the limited edition silver age All Might hoodie, still thinking it is stupid that courage overflows from the hoodie according to Koichi's belief. Although she thinks it is dumb, deep down she believes there to be some truth in his belief.

Stendhal Arc
Days later, the Crawler and Pop☆Step go out to perform a patrol without Knuckleduster. They are surprised to see meet Akira Iwako, who is attacking innocent civilians again in his Instant Villain form. While Koichi lure the villain away to a less populated area, Kazuho phones Knuckleduster to ask him if Koichi can pull the situation off on his own. He replies that Koichi doesn't stand a chance, and the best thing they can do is just buy some time and call for help.

During the fight, Koichi loses his balance and he is about to be punched by Akira. Fortunately for him, he is saved by a masked vigilante called Stendhal, who attacks Akira with his weapons, forcing him to escape. Koichi thanks Stendhal before he leaves. This meeting made a great impression on Koichi.

When Kazuho and Koichi return to the penthouse, they tell to Knuckleduster about what happened. Koichi stars gushing over the masked vigilante but Knuckleduster warns him that guys like Stendhal. Kazuho receives a message from Ichimoku Samazu and Jube Namimaru, who say that Ichimoku's strong friend from his hometown is coming to visit and wants to meet Koichi and his fellow vigilantes at Ichimoku's family restaurant. Kazuho decides that they will meet with Ichimoku's "senpai".

At Ichimoku's family restaurant, Koichi and Kazuho are surprised that Ichimoku's "senpai" is none other than Soga Kugisaki. Soga is disheartened by their reactions and questions why they think poorly of him, to which Kazuho replies that he assaulted her and tried to murder them. Soga is annoyed and leave before they can talk.

What they did not know was that Stendhal had formed an alliance with villain Kuin Hachisuka to murder former Trigger consumers, with Soga and his friends being targeted. During a patrol, Koichi finds Stendhal attacking Soga and seriously injuring him. Koichi tries to help but is also injured. Fortunately Knuckleduster appears and defeats Stendhal, forcing him to retreat.

Kazuho Haneyama arrives with a first aid kit and begins applying bandages to Koichi and Knuckleduster. Knuckleduster asks Kazuho to tend to Soga's injuries, which she begrudgingly does despite her animosity towards him. Koichi is glad to have made it out of this incident alive. Soga is annoyed by Koichi's optimism and questions Kazuho about it, to which a blushing Kazuho replies that he is nothing but a happy-go-lucky idiot. Soga seems to understand the way of being of both Kazuho and Koichi.

Vs. Queen Bee Arc
After their confrontation with Stendhal, the Naruhata Vigilantes continue with their routines. Kazuho is at Kocihi's penthouse killing time when he hears him arrive with a girl. Kazuho hides while Koichi unlocks his door and asks the girl to wait outside while he tidies up the place, throwing all the junk right where Kazuho is hiding, and then allows his companion to enter. The girl's name is Makoto and she is his senior at the college where he studies. Makoto had offered to help Koichi with his studies, and in return she asks him to help her with her field survey investigation about the rumored "Naruhata Vigilantes" for her thesis about vigilantism.

Despite the fact that he is precisely a member of the so called Naruhata Vigilantes, Koichi agrees to help her. When Makoto leaves, Kazuho appears and is not in the best of moods due to what had just happened. She is annoyed with Makoto's interference, appearing out of nowhere as if she owned the place. However, Koichi does not take Kazuho's rants to heart as he is doing his college work. The next day, disguised as Pop☆Step, Kazuho spies on Koichi and Makoto while they carry out the survey about them. Except for a small incident in which a barker tried to steal Makoto's laptop, nothing remarkable happened between the two of them. At night Koichi and Kazuho are looking through copies of Makoto's data and sniping at each other for their perceptions.

A few days later, while she and Koichi chase a thief on a motorcycle, Koichi is saved from being hit by truck by a new hero who has just arrived to Naruhata, Captain Celebrity, a the top-ranked American Hero. Later Knuckleduster tells them that Captain Celebrity is known for multiple lawsuits filed against him and been subject to multiple scandals due his infidelity. Koichi can't stand him due to his arrogant and pompous attitude, especially after an incident with a monstrous villain in which Captain Celebrity doesn't participate until the television cameras and his personal staff arrive. The american hero defeats the villain very easily even though he is very reckless, putting Koichi in danger.

Captain Celebrity poses at the cameras and brings in his personal cheerleader squad to cheer at him. As Captain Celebrity and his cheerleader squad show off, Kazuho sees that Koichi is annoyed at Captain Celebrity hogging all of the spotlight and Koichi admits that he is jealous of Captain Celebrity. Suddenly, they spot Makoto who is one of the cheerleaders. Pop☆Step finds Makoto to be vulgar for jumping around in her cheerleading mini skirt, but Koichi begs to differ while referring to Kazuho's own revealing apparel which she refutes. Being a renowned Casanova, Captain Celebrity invites Makoto out on a date, she accepts and she ends up revealing that she is in contact with his wife Pamela, which Captain Celebrity fears because of her lawsuits against him. In this way, Makoto becomes her manager, ready to improve his public image.

Days passes and one morning, when Koichi receives a call from his father, Kazuho is surprised to see him all hysterical and to clean and tidy up his residence as quickly as possible. Koichi replies that his strict mother, Shoko Haimawari, is coming to visit him. He remembers his updates to her, including one that states he has a girlfriend. In fear for being scolded for lying, he wonders what he should do. Blushing at the idea that he might ask her to pretend to be his girlfriend, Kazuho decides to leave to disregard the matter.

Despite this, Kazuho later decides to help Koichi with his mother, and wears a dress, although Koichi had already asked Makoto for help in that regard, although his mother quickly discovers the lie, she befriends Makoto right away. When Kazuho sees Makoto is there, she starts to leave but Koichi stop her and offered her to stay for play up his popularity with his mother. Although Kazuho does not like that mess, she agrees and uses her actual name to introduce herself to Shoko and Makoto. Koichi is glad to know Pop's real name.

Then Koichi and Kazuho panic when Knuckleduster shows up, terrified of the reaction he may cause in Shoko and Makoto when they see the violent vigilante, but to their surprise, on that occasion Knuckleduter is seen as more genuine than his previous self, politely introduces himself to the guests and presenting a perfect façade of a worker for a local non-profit organization in charge of protecting and support the streets of Naruhata, assuring Shoko that her son help them a lot. Both Koichi and Kazuho realize that, metaphorically, he is telling the truth, but he's omitting a lot of details about how he's doing these things.

Makoto notices Knuckleduster’s strong built body and ask him he is a former hero, causing the mother mentions that she doesn't like heroes, and her son's desire to be one has only caused problems. Kazuho tries to stand up for Koichi, but her nervousness causes her to run away while Makoto states to compliment her.

The mother starts to worry about her and order her son to chase Kazuho down. Koichi finds her down the stairs and tries complimenting by saying her dress looks very casual. This comment does not seem to please Kazuho, who slaps him before leaving for her home. Koichi returns to his penthouse and his mother decides to go sightseeing in Tokyo with Makoto next day.

Koichi spends the next morning with Makoto and his mother touring Tokyo, but when they get on the bus that will take them back, Kuin Hachisuka causes another havoc by injecting Trigger to a cat with quirk, taking control of the vehicle and goes out of control. Knuckleduster notices the ruckus, and when he sees Koichi and his guests in danger, he calls Kazuho Haneyama for assistance. Kazuho arrives immediately at the place, bringing with him the feather duster and the duct tape that Knuckleduster had asked for.

With these items, he creates a cat toy and uses it to divert the vehicle onto a road long enough so Koichi, with the help of Ingenium and his team,can rescue all the passengers before the bus reaches the dead end. The last to leave are Koichi with Makoto in his arms, just as the bus begins to fall off a bridge under construction. By sheer force of will, Koichi pushes his Quirk to the limit, allowing him to double-jump in midair, saving both.

Later at Koichi's penthouse, Shoko says goodbye to her son, reassured that he is at good hands, and she asks Knuckleduter and Kazuho not to hesitate to punish him if he steps out of line. Sometime later, Kazuho starts to measure how high Koichi can float, in which he’s able to do 30cm. Kazuho informs him with practice, he could possibly do 50, in which he could float over curbs. Koichi states he used the power before as a double-jump; and despite Kazuho thinking it was all in his imagination, Koichi states he did it in which it seems he cannot replicate again.

A few days later, Kazuho receives an email request from her blog that asks her to join a live event on the roof of the Marukane Department Store. She fears that since people view her as a singing street performer and if she screws up they would desert her, yet this is a chance that does not appear often. To help her, Koichi brings Makoto to help with the situation at hand. Kazuho gets mad at Koichi for her knowing her secret identity, to which he replied Makoto has sharp intuition, and that she already knows that he is the Crawler due to the bus incident. Makoto promises to Kazuho that she would not mention her masked escapade to anyone.

Kazuho ends up being part of Feather Hats, a musical group composed by her; Feathers, an underground idol duo of twins named Miu and Yu, the band Mad Hatters and the East Naruhata High Dance Squad; and thanks to Makoto's business skills and contacts, She gets sponsors for Narufest. During the following days, while the Feathers work in intense training sessions with the ENH Dance Squads, Kazuho practices singing the song at Koichi's home.

Miu sprained her ankle during her workout, so Makoto and the others try to figure out where to position her so she doesn't have to move too much. Makoto proposes putting Kazuho in the middle with the Feathers on either side of her, or cutting out Miu completely and having Kazuho and Yu perform as a duo. Miu gets sad that after all of her hard work, she won't be able to perform. Kazuho suggests putting Miu in the middle, having Yu move back and forth to either side of her, and jumping around herself behind them both.

The night of the premiere, in the greenroom, Kazuho Haneyama begins to feel nervous about going out on stage. However, a villain causes a blackout and everyone is worry that the show is called off, and Pop☆Step notices that Koichi Haimawari has gone off somewhere. Koichi emerges from the crowd as The Crawler. He gives Pop her microphone. Pop agrees with the plan for her to go on stage and keep the audience calm.

Pop☆Step explains to the crowd why the power went out, and that the staff are working hard to restore it. She then introduces herself to the audience. Pop instructs those with glow-sticks and assorted light-up goods to line up at the edge of the crowd, and for the rest of the audience to move a bit towards the stage to make a path. She tells the gathering of people that they have time to go to the bathroom before the main event, and that in the mean time she will perform a few songs. Miu & Yu note that she did some slick work on the stage. They also mention that she was as lame as ever, but kind of cute.

When the power is restored. Pop☆Step tells the crowd that the show will begin. The Feather Hats perform their remix of the Marukane Department Store Jingle, and they are greeted with great applause and cheering from the crowd, that's goes wild after the Feather Hats finish their performance.

Thanks to the show, Kazuho's popularity as Pop Step grows a lot, still she continues working as a vigilante. During the days after the festival, Knuckleduster is increasingly absent, until finally he leaves without saying anything to anyone, leaving his mask and brass knuckles at Koichi's penthouse. Kazuho wonders why Knuckleduster would leave them there since they just parted in town.

Osaka Incident Arc
Days later, Kazuho is chosen to represent Marukane Department Store in a regional idol collaboration show in Osaka, celebrated on SS Mall in Super Minami. At the station, Koichi miss the train to Osaka because he was pre-occupied with buying bento boxes. Kazuho phones to inform what happened when Koichi suddenly enters his car, much to her shock.

Koichi explains he manages to jump onto the side of the train and stick to it, finding out a new use of his Quirk by using the repelling forces from his hands to make like suction cups. Kazuho admits that she is impressed but says the way he discovered this new application of his powers was ridiculous. As they go out into the city Koichi cannot help but to try out his new ability. Kazuho tells him to knock it off.

Along the way to the SS Mall, they meet Fat Gum, who tells them in the address. Later, on the green room for the Mascot Idol Carnival inside the mall, Kazuho is recognized as Pop Step by Monika Kaniyashiki, an idol whose who works for the Kanidoge chain.

After interpreting the theme of Marukane Department Store in the Idol Show, Kazuho and Koichi decide to see the exhibitors and the souvenir shops of the venue. As they walk, they find Monika riding a crab-shaped Mech. That the Kanidoge's uses as walking advertisement. Monika has to leave for some business, and as it takes too long to return, her manager asks Kazuho to handle the mecha.

What they did not know is that Monika is a covert police investigating the illegal traffic of trigger, that used the products of Kanidoge to distribute the drug throughout Japan. Investigating Monika and the police find the main suspect, who activates a code that makes the Kanidoge’s mechas go on a rampage, and takes advantage to destroy all the evidences and escape.

When this happens, Kazuho is now trapped in a rampage mech, unable to free herself or stop the machine. Koichi tries to help her but fails. Fat Gum and Kaniko arrive and chase the mech to stop it. Monika asks Fat Gum to throw her to the mecha, allowing her to use her Super Move Rocket Crab Clip, and the mecha’s legs, preventing it from moving forward.

Monika quickly rescues Kazuho, just when the mecha starts its sequence of self-destruction. Monika, Koichi and Kazuho run as far as possible from the machine before it blows up, warning everyone present to leave. But Kazuho stumbles and Koichi launches to protect her, still too close to the mech.

At this moment, Fat Gum appears and jumps to block the explosion of the Mecha, absorbing all the kinetic energy with his Fat Absorption Quirk, saving Koichi and Kazuho's life. He holds enough time for everyone to move away before releasing all the energy, at the cost of his protective fat.

To avoid problems, before they can be questioned by the police, Kazuho and Koichi leave the convention, and sleep on the train on the return trip.

Sky Egg Arc
After the incident at the idol show, Kazuho returns with her daily life to continue with her studies, act in the Narufest of Marukane, and help Koichi from time to time when he decides to perform his activities as a vigilante. During one of his patrols, Koichi discovers a new power of his Quirk, the ability to shoot repulsion force blasts, which he names it as Scrappy Thrust Style. He later shows to Kazuho this new power, explaining her the process to execute it and starts throwing blasts until he accidentally breaks a windowpane.

The next day, despite her scold, she surprises Koichi training the Scrappy Thrust Style. She scold him again, and advises him to not shoot repulsion blasts because he could get into trouble. Koichi acknowledges that she is right, although his power proves to be handy during the fight against Octoid.

Although Koichi's carefree attitude was a problem, Kazuho continues to feel something for him, and this caused him to be involved in the police investigation about trigger distribution. It turns out that Koichi is invited by the Mad Hatters to participate in a mixer where to meet other girls. Moved by jealousy, Kazuho follows Koichi on his way to the mixer, casually meeting the hero Midnight, who explains that one of the girls is suspected of trafficking with trigger. Midnight asks Kazuho for help, and using his influence, he can both participate in the mixer in disguise and with fake names.

Thanks to her costume Koichi does not recognize her. After a series of events, Rin Yaritezawa, the girl considered suspicious of being the trigger dealer, falls for Koichi, which awakens not only Kazuho's jealousy, but also Hina's, the real trigger dealer. Hina tries to drug Koichi's drinks with trigger, but due to a number of circumstances, the drinks that she offers to Koichi end up being drinks for other customers of the bar, resulting in them starting to lose control over their Quirks.

Midnight uses her Somnambulist Quirk to put everyone to sleep, and arresting Hina in the process. The mission makes Midnight and Kazuho become friends, to the point that Midnight gives Kazuho her cellphone number to call her if she needs help.

By the end of December, the Marukane Performers decide to celebrate Christmas together in Marukane. Kazuho enjoys the festivities along with Koichi, Makoto, Captain Celebrity and many others. When the party is over, Kazuho congratulates Captain Celebrity for the good news that he will be a father and will be able to return to the United States.

After the party, the Little Sisters of Saint Lila's Academy get into a taxi, but from the sky appears a flying creature that takes the taxi, with the girls inside. Captain Celebrity goes out in pursuit, but just when he is going to reach them, the creature explode. Fortunately, Captain Celebrity manages to rescue the girls on time and unwounded.

This feat made Captain Celebrity's probability increase, and on the occasion of his return to the U.S., Makoto decides to organize a spectacular farewell party at the Tokyo Sky Egg, inviting numerous professional heroes for the occasion. Kazuho, as well as the other members of the Marukame, are surprised to learn that they will also be part of the Show. When Kazuho starts discussing that with Miu and Yu, they freak out when they realize the size and notoriety of the event in which they are going to participate.

During the weeks leading up to the event, Kazuho prepares intensely with his teammates: train for the performances, study the dances choreographies, organize the costumes, etc. She is so focused for the show that she hardly pays attention to anything else, even ignoring Koichi.

After several weeks, the farewell party of Captain Celebrity takes place. The event has a great success among the attendees, who enjoy the various acts, the participation of the heroes, etc. Kazuho and his companions go out to dance and perform for the public.

However, that celebration is suddenly interrupted when the Tokyo Sky Egg is attacked by five creatures equal to the one it attacked during Christmas, known as Bombers. Captain Celebrity comes out to face each other, but the Bombers damage the structure, and Captain Celebrity must use his strength to prevent the building from collapsing with thousands of people inside, being defenseless against the Bombers' attacks.

That attack had been orchestrated by Number 6, an agent of the Villain Factory, a criminal organization responsible for Trigger's traffic and several villain attacks in recent months. Number 6 had also been responsible for the attack during Christmas, made to discover some weak point in the Captain, and had meticulously planned that attack to assassinate him.

Nonetheless, thanks to the intervention of Koichi and the heroes who were there, they manage to defeat the Bombers. Frustrated because his plans has been dismantled, orders the last bomber to self-destruct in a poweful explosion, making the Tokyo Sky Egg begins to fall down. Fortunately for everyone, All Might arrives on time to save everyone, landing the Tokyo Sky Egg dome safely.

After thwarting the attack, Kazuho and everyone of the Marukane Performers, from the performers to the staff, decide to stay and help, are handing out for free official merchandising of the event (hoodies, food, drinks,...) among people to help them feel better. Number 6 makes a last desperate attempt to cause the greatest number of victims, but his plan fails again thanks to All Might, and this time the villain decides to retire.

During the days following the attack, Kazuho helps take care of Captain Celebrity, who is in the hospital recovering from the serious injuries he suffered from the Bombers. After two weeks, Captain Celebrity manages to recover enough to being able to return to the USA with his family. Aat the international airport, the Marukane members meet to say goodbye to them. To the surprise of Kazuho, ​​Koichi and the Captain, Makoto announces that she is also leaving for the United States to attend a prestigious university and continue her studies.

That night, Koichi returns along with Kazuho to his penthouse. Once there, they start talking about Makoto. He talks about Makoto's departure and how well she handled the press, but Kazuho thinks she could have given Koichi more credit. Koichi thinks that some credit would be fine, so tells Kazuho that if she wants she can praise him, but a flustered Kazuho replies that he can't ask for it like that.

Final Performance Arc
Three years have passed since Koichi became a vigilante. Throughout that time, Koichi has been protecting Naruhata from malefactors and helping local people, to the point that he is considered a local hero. During all that time Kazuho has been helping him with his vigilantism tasks. However, things are starting to change. To her surprise, Koichi confesses that his days as The Crawler are about to end. Once he gets a job, he'll have no business playing hero anymore and stop being a vigilante. His words surprise Kazuho.

In Marukane, things are not going well. Since she went to the United States, former manager Makoto has been successful and has become a celebrity in the country. However, with her departure, the success of the Marukane Performers began to decline progressively. The Narufest is becoming less and less popular, and the Marukane's directive has been slashing their budget. Gradually its members began to leave, nowadays too busy with jobs or studies, to the point that only Kazuho, Miu, Yu and the Sisters of Saint Lila's Academy remain.

Because their last show did not have much audience, the remaining members have gathered to suggest ideas that can boost attendance, but they don't find the right solution. Miu does not take the meeting too seriously, commenting that she is now interested in finding a boyfriend during high school. When mentioning this, she asks Kazuho how her relationship with Koichi is going, which makes her very nervous. She tells Kazuho that she risks that Koichi will move on and take an interest in another girl. Yu tries to stop her sister, although she acknowledges that many things have changed since then, and tells Kazuho that she should think about her relationship with Koichi.

At that time, their new manager Nomura enters the meeting room and communicates the bad news. Despite his efforts to try to convince them of the opposite, Marukane's executives have decided that next month's Narufest will be the last. This saddens the girls, although it was somewhat predictable, and they decide to end the meeting.

Kazuho walks back to the penthouse, sad because the group is going to break-up soon. While walking, she thinks about Miu's words, and decides to cook curry for Koichi. Upon arriving the penthouse, she is surprised to find that Makoto was there, cooking curry. After dinner, Makoto tells Koichi and Kazuho that she has decided to return to Japan, despite her success in the United States. Makoto asks how things are going with Narufest. Kazuho tries to answer her but Koichi does it first, saying it is rollin' along just fine. Kazuho decides to play along.

Then Kazuho decides to leave the penthouse, but she barely steps away when she regrets not telling Makoto the truth. When she turns around, she sees Makoto hugging Koichi and eavesdrops their conversation. Makoto confesses her feelings for Koichi, who is surprised by her confession and doesn't know what to answer. Although Makoto would like her feelings to be reciprocal, she decides to give Koichi time to think well about her answer, as she also takes into account Kazuho's feelings. Makoto is sure that Kazuho is in love with Koichi too, so she gives him time to figured out how he and Kazuho feel about it before he make his decision. The whole conversation leaves Kazuho confused and nervous.

That conversation makes Kazuho evasive with Koichi the next morning. At night, she understands that she needs to put her thoughts together and confess her feelings to Koichi. But when she compares with Makoto, Kazuho realizes that she is better than her in any aspect. In addition, she knows that her success is thanks to Makoto. Depressed, she starts watching online videos of when she started performing in the streets as Pop☆Step, being still very young. The clip of her first performance gives her the courage not to give up.

The next day, after talking with her companions on how to organize the last Narufest, Kazuho decides to perform a solo performance at the streets. She can barely sing as three thugs appear mocking her. Fortunately, the manager Nomura also appears and takes her out of there before there are more problems.

The two go to a café, where Kazuho explains to Nomura about her solo project. Kazuho explains that she tries to craft a future for herself beyond the Narufest. Nomura asks Kazuho to let him listen to her song, getting too excited for its lyrics and composition, so he decides to help Kazuho and offers himself to be her producer, so everyone can listen to her song. When they leave, they meet again with the trio thugs. Their leader attacks them, but Nomura manages to defeat him and restrain him with a hold. Nomura tells him that he is a hero, and he shows his hero license to prove it.

The next day, per Nomura's advice, Kazuho tries to convince Koichi to obtain his hero license. She tells that he could get his license while still doing his day job. Koichi dismisses the idea because it would be too difficult for him and asks her why she is so interested in what he does to which she denies that she does. While on the topic of the future, Koichi tries to talk to her about another matter, but Kazuho apologizes because she has to get to a meeting at Marukane.

She promises that she will hear him out later. After the meeting, where everyone agrees to contact the FeatherHATS members for the last Narufest. Kazuho and Nomura leave quickly to carry out a street performance. Kazuho sings one of her songs, obtaining great success among passersby.

After this, Kazuho and Nomura celebrate the success of their performance at a bar, where the manager tells him that his real name is Rokuro Nomura. After finishing, while they walk the streets, Nomura confesses that he wants to be her producer and do everything for her. Kazuho feels flattered by his words, but she tells him that her songs are for herself and give herself courage. She leaves giving thanks to Nomura for everything.

Kazuho feels sure of herself and prepares to confess her feelings to Koichi, but suddenly loses that confidence when he shows her the tie Makoto gave him for the interview, and leaves immediately without saying anything to Koichi. Confused, he tries to ask Kazuho what happened, but she had already left. At her home, Kazuho locks herself in her room and phones Nomura. Crying, she apologizes for rushing off earlier and tells that she needs him to be there for her. Nomura replies that he is there to help her.

The two agree to meet in a café, where Kazuho tells him that she still does not have enough confidence in herself. Nomura responds by telling her the appropriate answers to encourage her, and suggests a change of scenery. He tells her that she should come and visit his own "secret hideout", taking her to a rundown building. Nomura apologizes for the place, but Kazuho doesn't mind because she knows someone who lives in a similar dump.

Then, Nomura takes Kazuho to the basement and asks her to enter a room. Thinking that there is a studio there, Kazuho does it, only to see a dark room and hear a strange buzz. As she walks into the room, the manager Rokuro Nomura decides to stop pretending, revealing himself as villain Number 6. He pushes Kazuho in and locks the door behind her. It's dark, but she quickly finds a pile of corpses in the corner, and that the strange buzz came from a swarm of bees.

After being missing for several days, her family informs the police, and her friends search for her all over Naruhata without finding her. Among them is Koichi, the most concerned because with his disappearance he begins to reflect on his relationship with her. While on a whipping, Koichi is attacked by various Bomb Bees, and the perpetrator is none other than Kazuho Haneyama, who becomes the Bee☆Pop after being the new host of the Queen Bee.

Arranged by Number 6, the now-possessed Kazuho begins rampaging the streets with explosives, all the while playing her music. Koichi tries to stop her, but is defeated and falls into a dark alley. After causing great destruction; Bee☆Pop says goodbye to all the "viewers", promising that she will return to offer them an even better show.

Next day, The media is reporting the bombing carried out by Bee☆Pop. One of the reporters on scene is comparing the level of destruction caused with that of the Kaiju Attack three years ago. The newscaster, Daikaku Miyagi reports that the police has identified Pop☆Step, a well-known idol from Naruhata, as the main person responsible for the bombings. Because of this, the authorities have register her as a villain through the villain designation registry. This sets a precedent because the designation and registry of a person is usually is reserved for repeat offenders charged with quirk-based crimes, and Kazuho's case is a rare exception due her age and the fact that this is her first offense.

Both her family and friends cannot believe what has happened to her. With the threat of her next "show", the heroes organize patrols in case she decides to appear. Meanwhile, Koichi was rescue by Soga and his friends, who explain the current situation to him and that Kazuho is controlled by a parasitic Queen Bee. During the following days, determined to rescue her, Koichi trains hard to improve his mastery and abilities of his Quirk, while Soga devises a plan to defeat her and free her from the bee. Analyzing the videos of the attack, Soga realizes that Kazuho seems to be in pain.

Soga's assumption proves to be right because, in a high-rise apartment, a possessed Kazuho is bloodied and nearly broken. She crawls from her bed to the apartment window to look out towards the city, while her mind is filled with violent thoughts confusing strong feelings of love and hate. She cries over Koichi, saying he will never forget about her, as her left eye bleeds.

A few days later, Bee☆Pop decides to take action. After remembering some moments of his childhood, where she tells his mother that she wants to be a performer rather than a hero, She starts bombing the streets of Naruhata and to hijack the radio spectrum and broadcast her rampage, while singing and dancing. More and more heroes begin to get to where Bee☆Pop is, although this does not worry her. On the contrary, their presence stimulates her even more to continue with her "Showtime", playing her musical theme "Inferno" once again.

One of the heroes there is Endeavor, along with his subordinates the Flaming Sidekickers. Despite the fact that Detective Naomasa wants to capture Pop, Endeavor considers her too dangerous a foe for it, so she decides to take even more extreme measures. After receiving the signal that the streets have been emptied of civilians, Endeavor attacks Bee☆Pop with his Super Move Karmic Raze - Hellfire Storm, which releases an intense hellfire tornado towards Pop.

Little by little, the bees begin to explode due to the intense heat of the flames, as the tornado gets closer and closer to Pop, who seems unable to react in time to the incoming, flaming death. However, Endeavor is forced to call off his attack when he is warned of the presence of another person at the scene, who turns out to be the vigilante The Crawler, who is there to save Kazuho. Endeavor is furious of his interference, but due to the drawbacks from his Hellflame Quirk, he is forced to stop to cool down his body. Meanwhile, the rest of the heroes are ordered to try to stop Bee☆Pop and The Crawler until Endeavor is ready to fight again.

Both Bee☆Pop and Koichi evade the heroes who try to catch them, with a little "help" from Number 6 who, posing as a pro-hero, kills several of them by shooting them without anyone noticing. After this, Koichi manages to get to Bee☆Pop, ready to stop her. The possessed Kazuho, after having a vision of what her life with Koichi would be like if none of that had happened, she declares that she’s gonna be singing her newest single “Bloom”.

Bee☆Pop starts singing her song, making the bees to attack Koichi as he dodges her precise explosions and fights back. Kazuho song reflects her own despair and sadness, and she wants everyone to know, especially Koichi. Thinking that she had already achieved what she wanted, Bee☆Pop finishes her song and the bees begin forming a circle around her. She is planning to blow herself up, ending her life. She wishes her death being so shocking that it will impossible for Koichi to forget.

Koichi is knocked down by one of Bee☆Pop's exploding bees, but by using a grappling hook he avoids falling to the ground and uses it to propel himself towards the controlled Kazuho one more time, using a double jump on top of that. Yelling out her name, he surprisingly makes his way to Pop. When she notices him, Kazuho's real mind begins to break through the mind control that Queen Bee has over her.

Seeing Koichi approaching her, Kazuho tries to reach his hand as she says his name. When they seem like they are about to pull it off, Kazuho gets shot by Number 6, who doesn't want that whole scene to ruin his plans.

In horror, Koichi immediately saves Kazuho and lands with little trouble in an alley. Once on the ground, Koichi checks that she is still alive. Right after, Number 6 appears in front of him and introducing himself as the hero O'Clock II and the one who shot Kazuho, ​​although he clarifies that the shot was not lethal, but was to inject a drug into Kazuho that alters the metabolism of the bees inside her.

At first Koichi calms down with the explanation, but it doesn't take long for him to find out that something is fishy with that "hero", especially when he starts a monologue about how every hero needs an arch enemy, being Koichi that person, and that the drug I inject into Kazuho makes the Queen Bee and the hive eager to self-destruct. Koichi watches in shock as Kazuho begins to convulse and a swarm of bees leaves her body. Koichi quickly carries Kazuho in his arms and run as fast as possible from the bees that are exploding around him.

Number 6's plan is: when the time is right, he will defeat the "villain" The Crawler but "tragically" will not be able to save Kazuho, who blows herself up, and after this "tragedy" he will swear on her wretched soul to never let such a thing happen again. In this way, he will create the “heartbreaking” debut of O’Clock II that will make people instant fans of him.

Seeing that Koichi is about to escape with Kazuho in his arms, Number 6 begins to chase him to finish him off, but soon Endeavor also appears, and begins to attack Koichi, without noticing the presence of the "hero" O'Clock II. Trying to stop Koichi once and for all, Endeavor his super move Raging Assault - Hell Minefield, and the ground begins to explode from the attack, forcing both Koichi and Number 6 to jump to dodge, but while Number 6 makes a miscalculation and is engulfed by flames, Koichi forces his Quirk to the maximum, allowing the Vigilante to blast off and fly into the sky, leaving everyone dumbfounded.

Up in the skies, an unconscious Kazuho manages to say his name. Koichi holds Kazuho in his arms and assures her that it’s gonna be okay, and uses his Slide and Glide Quirk to head towards the position where his allies are in order to extract the Queen Bee from her, unaware that they have been spotted by Midnight, who follows them.

Once in place, Soga prepares to perform the operation but Koichi stops him, warning that Kazuho has been shot with a drug that disrupt the Queen Bee. Faced with this unforeseen event, Soga no longer knows whether to continue with the plan, but at that moment Midnight appears, reassuring everyone by saying that she is a friend of Kazuho and she is there to help.

After Koichi and the others explain the situation to her, Midnight uses her Somnambulist Quirk on Kazuho, ​​putting both her and the parasitic bee to sleep. Now all they have to do is take Kazuho to a hospital where she can receive the appropriate medical care.

Endeavor had also followed them and appears to stop Bee☆Pop and The Crawler, but Midnight explains that they have already captured the villain Bee☆Pop has been captured and she urgently needs medical care. And for The Crawler, he slipped away. Endeavor allows to take Pop to the hospital, as he is sure that there is something bigger in the whole thing, and wants to interrogate her.
