U.A. Sports Festival Arc
In the Obstacle Race, Hanta avoids Shoto Todoroki's ice with his Quirk and stays in the race. He and Fumikage use their Quirks to climb over the humongous Villain Bots to get to the next area by following Katsuki's advance. Hanta manages to place 8th in the Obstacle Race, allowing him to participate in the next event, the Human Cavalry Battle. He teams up with Katsuki along with Eijiro and Mina Ashido.

After the Human Cavalry Battle begins, Katsuki jumps into the air and tries to attack Izuku Midoriya with an Explosion, but Fumikage uses his Dark Shadow to block it. Hanta uses his Quirk to catch Katsuki so that he can land safely back on his team's formation, which Eijiro praises Hanta for. After Neito Monoma takes his headband without trouble and mocks him for always being attacked by villains every year, Katsuki, infuriated, states that they will beat them first before going after Izuku.

Hanta and his team continue to battle Neito, who manages to rebuke their efforts. However, Katsuki eventually manages to grab two of Neito's headbands and Hanta uses his tape to grab Katsuki to reel him back onto the formation, with Hanta complaining that Katsuki did not warn them when he is about to jump off. However, Katsuki still wants more points and orders his team to attack; having Hanta use his Quirk and has Mina use her dissolving fluid. Hanta and his team ride on Mina's fluid to reach Neito's team faster thanks to Hanta reeling in his tape. Katsuki attacks Neito for the final time and grabs his last headband, which places their team at second place. Katsuki, however, wants to collect the ten million point headband and Hanta goes with his team to where Izuku's team and Shoto's team are.

Hanta and his team reach their destination, but the Human Cavalry Battle ends before they could do anything. However, Katsuki's last minute actions allowed Hanta and his team to reach second place, allowing them to participate in the final event. The final event is a tournament event and Hanta's opponent in the first round is Shoto. He is seen partaking in one of the recreational events.

Hanta steps into the ring to face his opponent which is Shoto. After the match begins, Hanta confesses that he doesn't know if he has a chance but states that he won't simply roll over. Hanta makes the first move, wrapping his tape around Shoto, attempting to throw Shoto out of the ring.

However, Shoto retaliates by using Giant Ice Ridge, creating a huge ice glacier that freezes the majority of Hanta's body and causes Hanta's tape to crack into pieces, which frees Shoto. Midnight asks Hanta whether he can move or not, to which Hanta replies in agony that he can't move. As a result, because he is unable to move and unable to do anything, Hanta is declared defeated and is eliminated as a result. The audience tells Hanta to not mind his loss. Shoto goes to Hanta, apologizing to him for overdoing it and then melts the ice off of him with his fire power.

Hanta, sitting next to Denki Kaminari, watches the match between Ochaco and Katsuki and notes that Katsuki is keeping a sharp eye against his opponent before making any moves.

Vs. Hero Killer Arc
Two days after the Sports Festival, Hanta is in class. During the Hero Informatics period, Shota shows the Pro Hero nominations which reveals that Hanta received fourteen Pro Hero nominations. Eijiro comments that the top two nominations are in reverse and Hanta replies that it is because the Pro Heroes seeing Katsuki in a straitjacket must have scared them off. Afterwards, Class 1-A has to decide on hero names. Hanta writes down and shows his classmates his Hero name. Hanta's Hero name is revealed to be The Taping Hero: Cellophane.

After Class 1-A is finished formulating their Hero names, Hanta is given his personalized workplace list in order to choose a workplace that he wants to train at. On the day of the workplace training, Hanta is at the train station with his class so that he can travel to the workplace of his choice by train.

However, Izuku suddenly takes the lead, greatly surprising Hanta as he sees the latter's better control of his Quirk and new skills though Izuku stumbles along the way, causing Hanta to take back the lead and win the race. All Might commends the group for improving their Quirks broadly since entering U.A. and asks them to prepare for the end-of-term test.

On the day of the exercise test, Mr. Principal reveals that Class 1-A will be fighting against U.A.'s teachers for their exercise test. Hanta is paired with Minoru Mineta and they must face Midnight in their test exercise.

Minoru, Hanta and Midnight arrive in an uninhabited city where Class 1-A's test exercise will take place.

The test begins.

Hanta falls asleep due to Midnight's Quirk and Minoru desperately tries to wake him up. Hanta is sleeping on Midnight's lap while she waits for Minoru, much to Minoru's jealousy. Eventually, Midnight goes to chase after Minoru, leaving Hanta sleeping nearby the escape gate. Minoru uses Hanta's tape around his mouth along with his own Quirk as his plan to stick Midnight in place which works, allowing him to rush past her and avoid her sleeping gas. Minoru goes to the escape gate and drags Hanta, along with himself out of the escape gate, allowing them to pass the practical test.

Back in class at U.A., Denki, Mina, Eijiro, and Rikido are crestfallen that they are unable to go to the forest lodge due to failing the practical test. Izuku tries to cheer then up, but Hanta tries to warn Izuku not to jinx those who have failed. Soon, Shota Aizawa enters the classroom and informs Class 1-A that all of them are going to the forest lodge which will be a boot camp; the students who failed are happy and relieved. However, Shota reveals that Hanta also failed the practical test due to being asleep the entire time and as a result, Hanta will be receiving harsher training at the boot camp. Hanta finds being asleep during the test to be more embarrassing than failing. Hanta, along with his class go to Kiyashi Ward Shopping Mall to buy necessities for the forest lodge.

Following the end of the semester, Hanta, along the rest of Class 1-A boys, is invited by Deku to participate in an endurance training session at the pool, an idea of Minoru and Denki. When Katsuki arrives and challenges Izuku, the boys opt to compete against each other by sprinting down the pool. When it is Hanta‘s turn, he tries to reach the other end of the pool using his Quirk without touching the water at all. Yuga Aoyama uses his Navel Laser to win the race, but in the middle of the flight, his Quirk begins to hurt him in the stomach, causing him to deviate and ends up crashing with Hanta, falling both to the swimming pool. Shoto wins the race.

Eventually, the field is shortened to Izuku, Katsuki and Shoto, but before they can start, Shota arrives and cuts their Quirks off due to their time limit for the pool expiring, kicking all the students out of the pool area.

On the day of the summer camp, they are informed that the new destination will be a mountainous region, owned by the professional Hero Team, the Wild, Wild Pussycats, where they will undergo reinforcement training to strengthen and upgrade their Quirks, also allowing Class 1-A to obtain their temporary licenses. Class 1-A's bus stops for a restroom break, where they meet Pixie-Bob and Mandalay, who challenge the students to reach base camp past the forest in three hours. Then, all Class 1-A is forcibly thrown into The Beast's Forest by Pixie-Bob's Quirk.

To reach their destination, they must traverse the forest, which is inhabited by dozens of hostile earth monsters created by Pixie-Bob. The Students work together to fight their way through the forest. Hanta uses his Tape on the wings of a flying monster and slams it on the ground.

The journey through the forest to the Cabin takes them around eight hours before finally arrive at the facility, battered and tired. Class 1-A fetch their luggage from the bus and put it in their rooms. Later they go to the dining hall and the Pussycats serve them dinner.

The next morning, Class 1-A are outside the training camp cabin. Shota greets his students and tells them that they will undergo reinforcement training to strengthen and upgrade their Quirks. To increase his capacity and improve tape strength and shooting speed, Hanta‘s training consists of having him producing tape continuously. Afterward, Classes 1-A and 1-B are tasked with cooking for themselves. While preparing, Hanta tells Katsuki to use an explosion to light up the oven. During dinner, Hanta makes an unfortunate comment about Momo's Quirk. Hanta realizes that her ability to create things from her body after eating is like pooping. She instantly curls up into a ball of shame and Kyoka punches Hanta in the face, ordering him to apologize.

After dinner, Hanta and the other students who failed their practical exams take extra lessons with Shota until two in the morning. Training starts back up at seven the next day. Hanta and the others are all super tired, but Shota forces them to train anyway.

At the third day of training, Hanta is happy because that night all the students will participate in a courage test. Shota, however, forces the extra lessons group to sit out for more teaching, much to their displeasure. The Vanguard Action Squad of the League of Villains invade that night. Mandalay sends out a telepathic message warning the students of their arrival. Shortly after Shota leaves, Mandalay sends out two more messages giving permission for students to fight back and informing everyone that Katsuki is one of the villains' targets.

The villains successfully kidnap Katsuki and the students return home from camp.

Hideout Raid Arc
After the capture of Katsuki, the training camp ends and Hanta returns home. Two days later, he visits Izuku in the hospital along with many of his peers, where he hears Eijiro and Shoto's plan to rescue Katsuki, asking Izuku to join them. Although he does not oppose the intentions of his classmates, Hanta does nothing to stop them.

Provisional Hero License Exam Arc
Following Katsuki's rescue and the retirement of All Might, Nezu transformed U.A. into a boarding school in only three days, in order to protect the students. Shota meets with his students outside of the building. He states they must start preparing to get provisional hero licenses like they had planned to during the training camp.

Before allowing Class 1-A students to enter in their new residence, Shota scold the entire class for having allowed five of them to rescue Katsuki without a license and did nothing to stop them. He further more says he would have expelled everyone but Katsuki, Toru and Kyoka, if it weren't for All Might's sudden retirement and asked them to stick to the rules from now on.

Class 1-A arrange their luggage in their respective bedrooms. Later that night, the boys of Class 1-A are in the common space on the first floor. The girls of Class 1-A show up and suggest a room showcasing competition. The class looks at each others room, until they check out Hanta's room, which consists of traditional Asian design. The girls compliment him on it and he takes it in stride.

The following day, Hanta, along with the rest of 1-A, are told by Shota that their next goal is to obtain their Provisional Hero Licenses. To ensure success in the Provincial Hero License exam, they will develop their own ultimate moves, along with the guidance of Midnight, Ectoplasm, and Cementoss in Gym Gamma..

Hanta continues to train with his classmates following up to the day of the Provisional Hero License Exam. Outside of the National Dagobah Arena, Class 1-A meets with students from Shiketsu High School and Ketsubutsu Academy High School. The exam participants all gather to hear the rules of the exam from Yokumiru Mera from the Hero Public Safety Commission. The students find out they will be tested on speed, with only the first 100 out of 1540 passing the first test being able to move on to the next. Each student has six balls, and three targets to attach to their body. Those whose targets have been hit are disqualified. Participants need to eliminate two students to move on to the next phase of the exam.

The room in which the students are in unfolds to reveal the arena, in which there are varying environments to battle in. As the exam starts, the rest of the schools all attack U.A. at once, however, Class 1-A is able to defend themselves thanks to their ultimate moves. Hanta uses his tape to catch several of the rivals' balls. Yo Shindo tells his fellow classmates that he will shatter their solid defense, and uses his Vibrate Quirk on the ground, unleashing a powerful earthquake that shatters the ground and and causing members of class 1-A to disperse.

Due to this attack, Hanta gets scattered, and has to defend himself from the attacks of the rest of the students while looks for his classmates. First he finds Ochaco, and later they notice Izuku fighting Camie Utsushimi (completely naked) and meet up on the way to help him. Hanta uses his tape to keep Camie away from Izuku while Ochaco arrives and tries to land on Camie but she dodges. Camie is disappointed that she can no longer talk with Izuku due to being outnumbered after Hanta and Ochaco's interference, so she retreats.

Hanta tries to go after her but Izuku advises against it because Camie's targets aren't showing up on her naked body, reasons there is no point in chasing after her. Then, Izuku awkwardly asks if Hanta and Ochaco are the real versions of themselves. He explains that Camie was able to transform into Ochaco and everyone gets embarrassed. Hanta excitedly asks if the fake Ochaco was naked and Izuku replies that she wasn't.

They hide behind large rocks and discuss their strategy. Izuku tells them they need to move quickly because thirty people have already passed the exam. Izuku, Ochaco, and Hanta talk about their situation and how rival students are starting to split up. Izuku tells Ochaco and Hanta that he will act as a decoy while they keep a distance from him and try to immobilize as many examinees as possible. Izuku, Ochaco, and Hanta prepare to enact their plan.

Izuku activates One For All: Full Cowl - Shoot Style and dashes past the group of examinees, being chased by them. Hanta catches up to him and asks him to carry them both into the air. When they reach a safe height above the ground, Ochaco releases debris attached to tape that traps their pursuers by sticking them to the ground. Izuku, Hanta, and Ochaco place their balls on six examinees and pass the first phase.

While they head for the winner's waiting room, they are spotted by Denki, Eijiro and Katsuki. Ochaco, Hanta, Eijiro, and Denki celebrate passing together. Upon arriving at the waiting room, they find that Shoto, Momo, Tsuyu, Kyoka and Mezo had already passed the round. Momo is glad that all of them passed. In the end, all the class 1-A students manage to pass the exam. While waiting for the organizers to prepare the second exam, which will consist in rescue victims of a large-scale terrorist attack, Hanta tells Denki and Minoru that Izuku got to fight Camie while she was naked. Both get jealous and started to antagonize Izuku.

The second phase of the exam begins and Hanta sticks with the rest of his class. He watches all the other students act professionally and sees the gap between first and second-year experience. Momo finds a man trapped beneath debris and Ochaco tries to float it. Momo stops her because there is an imbalance in the debris. Momo creates metal pillars and Hanta Sero tapes them together, reinforcing the wall. Ochaco begins clearing out the rubble. The man finds Momo, Ochaco, Hanta, and Rikido Sato's rescue maneuvers not to be shabby.

Despite they reputation as the best candidates for heroes of the U.A., they are actually all a bunch of easygoing eccentrics. Class 1-A get confused when Mirio Togata challenges them all to a fight.

At Gym Gamma, Mirio tells Class 1-A to attack him whenever and wherever they want. Hanta, like the rest of his classmates, attacks him, but Mirio completely wipes out Class 1-A without breaking a sweat, thanks to his Quirk, Permeation. While Class 1-A recovers from their defeat, Mirio asks them if they think his Quirk is strong, and Hanta, with Toru and Mina, replies that his Quirk is too strong. Mirio explains how his Quirk works and advises class 1-A to participate in the Hero Work-Studies, as it will help them improve their career to be heroes, just as it helped him become one of the best students in the U.A.

Remedial Course Arc
Weeks later, after the police raid at the base of Shie Hassaikai, Izuku, Eijiro, Ochaco and Tsuyu return to their dormitories at the school, where Hanta, along the entirety of Class 1-A, is checking to make sure his classmates are doing okay after their mission.

Joint Training Arc
Shota Aizawa and Vlad King hold a Joint Training Battle between their classes during the early days of winter, with Hitoshi Shinso as a guest for this exercise, due being reviewed for consideration into the Hero Course. Vlad King and Shota begin the exercise immediately afterward. Each class chooses lots to split into five teams of four. As the teams are set, Hanta is placed with Katsuki, Kyoka, and Rikido, and they will face Class B's team of Yosetsu Awase, Setsuna Tokage, Kojiro Bondo, and Togaru Kamakiri at Round 4.

Before the fourth round of the Joint Training Battle, Hanta and his team went over a strategy as Katsuki and his team discuss their strategy. He listened as Katsuki wanted to take the lead and charge ahead with the others serving as back up. Katsuki gives each of them one of his grenades and tells them that he'll save them if they get in trouble and asks them to do the same for him.

When the round start Katsuki rudely tells Hanta and Rikido to follow his lead and orders Kyoka listens for the other team while trailing them. Hanta spoke up against this, believing that they should lie in wait for an opportunity but Katsuki mocks him and argues that they need to act first and create their own opportunity. Hanta is annoyed by Katsuki's bossiness.

Class 1-A charges through Ground Gamma when they are ambushed by Class 1-B team. Setsuna's Quirk lets her spread out her separated limbs throughout the field and uses her tiny body parts to attack them. They barrage Katsuki with rapid-fire small hits and Hanta uses Barricade Tape to protect his team, so that the lizard parts cannot attack and proceeds to call Katsuki over.

Setsuna says that they are done for. Kojiro appears and uses Glue Squall to spray his adhesive all over Hanta's tape barricade. Hanta tries to lead the three of them away but Togaru uses his Quirk to slash a large pipe that crashes down toward the other team. Rikido tries to sacrifice himself to hold it up but Katsuki manages to fire a large enough explosion to save his team.

Class 1-B decides to retreat after seeing that his plan has failed, but Katsuki is not willing to allow it and chase them. Yosetsu himself and bond Katsuki with his newly developed Super Move "High-Speed Construction: Weldcraft". Yosetsu runs away and hides within the pipes so Hanta can't get a clear shot off with his tape. Hanta realizes that Setsuna's eyes are making it easy for the other team to read their movements and decides to use his Quirk to search for one of her disembodied parts.

Rikido acts quickly and free Katsuki from his restraints. Katsuki flies at Yosetsu, but gets out of the way 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. Class 1-A also quickly captures Kojiro and Togaru, leaving only Setsuna to capture.

Hanta notes that although Setsuna's Quirk allows her to split apart into 50 parts, she appears to have a time limit to how long she can regenerate herself some spare parts. He surmises that she likely has to return her other pieces when regenerating to avoid going over her limit. Hanta attaches Katsuki's grenade to one of her pieces. Setsuna notices the grenade and avoids the blast, but she plays right into Katsuki's hands, who defeats her.

The fourth Round of the Joint Training Battle ends with Class 1-A scoring a perfect victory with 4-0. Shota Aizawa commends Team 1-A for being able to cooperate well enough to reduce battlefield damage and efficiently capture the opposing opponents without any hassle.

My Hero Academia: Heroes: Rising
During fall, the Hero Public Safety Commission devises the Hero Work Recommendation Project, to help to train the new generation of Heroes due All Might retirement. Weeks go by, and shortly after winter begins, after the Hero Interview Training, Class 1-A is sent to Nabu Island, a remote place in southern Japan. The Pro Heroes who protected the island are about to retire, so the students will take care of the place, performing duties as real heroes acting like their own "Hero Office", until the arrival of new Pro Heroes.

Because Nabu Island is quite isolated from the rest of the country, and therefore far from any villain activity, there has been no notable incident since the last thirty years. For this reason, their work on the island basically involve mostly minor deeds. Hanta works alongside several of his classmates on the beach as lifesavers. He and Fumikage prohibit tourists from entering the rocky area as it is too dangerous. Hanta uses his Quirk to create a warning sign.

At night, after working all day, all Class 1-A students mention that despite they only did minor deeds, this kind of hero work is still hard, even though they're not fighting anyone. Then, the grateful island citizens bring a bunch of food for the kids as a token of appreciation for their help. After dinner, Hanta, Denki and other students invite Eijiro to join them at the onsen bath and says that Katsuki can't go because he has to patrol the grounds since he didn't do any hero work all day long. Katsuki complains, but the guys leave him be.

The next day, while Hanta and several class 1-A students wait in the office waiting for a request, a neighbor and Fumikage arrive to report that the island is being attacked by a group of villains. Tenya quickly organize the class to face this crisis. He splits the Class into groups in order to deal with the separate threats: Hanta, alongside Tenya, Shoto, Sato and Fumikage will fight the villain at the beach as Ochaco and Koda assist with the evacuation of the tourists and residents.

Once there, they fight Chimera, but despite outnumbering him, the villain is superior to the students. At one point Hanta uses his Tape as Shoto uses his ice to restrain Chimera, but the villain uses his enormous strength to break free. Chimera continues fighting the students until he sees a flare in the sky. This was a sign from his allies indicating that he must withdraw. Chimera obeys the order and leaves.

At night, the students retreat to a factory to heal their wounds and provide first aid to the inhabitants of the island. Hanta helps bring supplies for students to prepare meals for refugees. Mina asks him about the villain that Katsuki had defeated, and Hanta replies that he is locked up and chained inside the machine room, but he refuses to talk to any of them after they questioned the villain.

Later, Class 1-A have a meeting where they discover that the objective of the villain leader, Nine, is to steal the Cell Activation Quirk from a boy named 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.

The next morning, Nine and his crew 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 as planned, the students take turns attacking Nine to force him to use his Quirks as much as possible, managing to disperse the villains. Following Izuku's plan, Hanta and Ochaco commence their assault on Nine by constantly throwing boulders at him. The villain uses his Laser Bullet Quirk to destroy the rocks and attack Ochaco and Hanta, forcing them to retreat.

They both go back to Minoru's position, where there is a trap they had set up for Nine: a large amount of rocks contained by wooden posts. Ochaco uses her Gravity Quirk to remove the posts, falling to the ground, exhausted, and having to be moved out the way by Hanta of the massive rock slide that she caused. Then Hanta helps Minoru, as he uses his Quirk to make the rocks stick together even harder to bury the villain. However, Nine is able to break free easily with his Quirks and the shock wave knocks down Ochaco, Hanta, and Minoru. The Villain prepares to shot a powerful attack on them when Izuku and Katsuki steps in and attacks him.

Deku and Katsuki continue to fight Nine, as the villain keeps using his various quirks to hold them off. Nine prepares to shoot them again, but Hanta intervenes and wraps Nine's arm with his tape and attacks him, but he is defeated after Nine uses his laser to blast him. Katsuki yells for his friend as Hanta falls to the ground, unconscious and unable to continue fighting.

While he 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.

Along with Denki Kaminari, Hanta makes fun of Katsuki because, as both find hilarious that all of Katsuki's footage from his interview after defeating a group of villains was cut out by the interview staff due his behavior. Later, he participates in a Hero Interview Training impart by Mt. Lady.

Days later, the Hero Work Recommendation Project takes place, staying on Nabu Island before returning.

Paranormal Liberation War Arc
Winter break is over and students return from their Work-Studies to continue their studies and show their progress with their Quirks and skills. At Ground Alpha, under the supervision of All Might, the students battle Villain Bots to show off the new skills and Super Moves they have developed. Denki, Hanta, and Minoru show off their teamwork and new team moves. Later at night, Hanta helps his classmates to organize a Work Study/Brainstorm/Hot pot party to energize everyone for the new term.

At some point, All Might asks him, Ochaco and Tsuyu to help Izuku with his training. Izuku explains he wants to learn to use Blackwhip more properly, which is why he asks Hanta for help because his Quirk, Tape, is similar in some way. Hanta accepts but asks if it would not be better if Shota Aizawa helps them in that matter. All Might explains that Shota is very busy with other matters at the moment which is why he isn't present. Understanding this, the three classmates help Izuku with his training, unaware that their assistance will also help to give Izuku some future control over Float when it manifests.

Months later, by the end of March, Hanta and several other students are involved in an operation to take down the Paranormal Liberation Front, the villain organization lead by Tomura Shigaraki. The Hero Public Safety Commission had uncovered the plans of the Paranormal Liberation Front, so they organized a large force of heroes to take the PLF 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.

Hanta is a member of the Villa Backup Team along with some of his classmates and Class 1-B students. When the operation start, Hanta tells Minoru to get up, but he retorts by saying that the rear guard's job is to catch anyone that slips past the front line, so getting pumped up would be an insult to the Pro Heroes, but Hanta tells him again to get up.

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. After being informed by Midnight, Momo devises a plan and communicates it to her teammates. She creates several vials filled with sedative and give one to each of them, explaining that the plan is to make Gigantomachia swallow at least one.

When Gigantomachia gets to where they are, he falls into a trap set by Momo and Juzo, at which point the students begins their assault. While some are in charge of facing the League's members he carries on his back, others, including Hanta, try to throw the vials into his mouth. The hulking villain blows them away with his powerful breath, but the students continue with the assault, and finally with the help of some heroes and great efforts, they get Gigantomachia to swallow a vial.

More heroes come to face the villains, but annoyed by the constant interruptions, Gigantomachia transforms, taking on an armored appearance, and with his enormous strength he finally manages to get out of the trap and easily defeat the heroes. One of the heroes, Majestic, used his Quirk to bring the students to safety before being defeated. Gigantomachia continues on his way to Tomura, destroying everything in his path. The students of U.A. watch with complete horror at the destruction left by the monster. An astonished Hanta asked his partner, Mezo, about the situation of the heroes, but he is unable to give him an answer. Dismay spreads between them to the point that some wonder if the drug really has an effect on the giant.

Two days later in Central Hospital, Hanta, Minoru, Toru, and Rikido are present in Katsuki's room when he woke up from his injuries. They are relieved with Katsuki's recovery, seeing his short fuse as a sign of wellness, much to Katsuki's annoyance. Katsuki then asks what happened to everyone else, but the students can't help but show worried expressions with the current state of hero society. After the Paranormal Liberation War ended, Sero returns to Height Alliance and then received a letter from Izuku explaining his origins as being Quirkless and the power of OFA, making his reasons to leave U.A High to guarantee his safety from AFO.

Tartarus Escapees Arc
A few days after Izuku left U.A., Sero 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. Sero notices Endeavor's phone, recognizing it as also having a GPS, and he tosses it, which several of the students catch. The classmates proceed to state their desire to help Izuku, how learning about One For All and his leaving was a shock, but still declaring they want to follow wherever he goes and help bear the responsibility he must carry. Once Principal Nezu gives them permission to bring back Midoriya to U.A, Sero volunteers to join with the rest of Class 1-A to search for Izuku while at the same time, apprehending any prison escapees along the way. After months of trailing Izuku's whereabouts, Sero and 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.

Izuku tries to escape with his Blackwhip, but Sero manages to subdue Daigoro Banjo's Quirk and wrap one of Izuku;s hands with his own Tape, preventing him from conjuring another one. Izuku remember that it was thanks to his advices that he was able to use Blackwhip more effectively and creatively in the first place.

Once Izuku rips the tape free, he is constantly attacked by several other classmates before being finally caught by Tenya and Kirishima. Sero rejoins with the rest of Class 1-A and listens to Katsuki apologizing to Izuku before he collapses from the shock and exhaustion.
