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.

After the Human Cavalry Battle begins, Katsuki jumps into the air and tries to attack Izuku 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 takes his headband without trouble and mocks him for always being attacked by villains every year, Katsuki 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.

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.

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, watches the match between Ochaco and Katsuki and notes that Katsuki is keeping a sharp eye against his opponent before making any moves.

Soon, Shota 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.

Following the end of the semester, Sero, along the rest of Class 1-A boys, is invited by Deku to participate in an endurance training session, an idea of Mineta and Denki (actually that was an excuse to be able to use the pool and be able to see the girls in bikini).

When is Hanta turn, he tries to reach the other end of the pool using his quirk without touching the water at all.

After dinner, Hanta and the other students who failed their practicals 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 villain's targets.

The villains successfully kidnap Katsuki and the students return home from camp. Two days later, Hanta 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.

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. When the class looks at each others room, 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 Aizawa that their next goal is to obtain their "Provisional Hero Licenses". To ensure successin 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 withhis 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. Sero 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 completely shatters the ground and and causing members of class 1-A to disperse.

Due to this attack, Hanta gets scattered, and have 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 emphatically 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 spoted 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.

Hanta passes the exam with 84 points, so he receives his provisional license.

Denki Kaminari remembers Katsuki having experience in playing drums which Hanta Sero agrees to. Katsuki refuses to as Hanta mocks Katsuki's inability to do so. Katsuki grabs some drum sticks and starts playing the drums proficiently. Katsuki's performance impresses Kyoka who wants him to play the drums. Katsuki begins walking away while expressing his disinterest. Katsuki also expresses his discontent with Class 1-A presenting the band and dance performance as a stress reliever, believing people who sicken him do not deserve his courtesy, and states that all they are doing is indulging the other students. Tenya and Momo Yaoyorozu take Katsuki's views into consideration as Shoto Todoroki points out that Katsuki should not speak ill of them if he has not even partaken in the conversation. Katsuki tells them that they do not fight villains because they enjoy it and likewise they should not consider people's feelings for a band and dance performance; if they are going to do a band and dance performance, they should do it for the sake of it and not to please or help people. Katsuki announces that he will blow everyone away in U.A. with his sound. Hanta and some of Class 1-A are surprised with Katsuki's willingness to participate.

Joint Training Arc
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. After Katsuki tells Kyoka to acts as the radio, Hanta spoke up against this while Katsuki mocks him and says that if they do not make the first move it is over for them. He says that they do not have time to take caution, they have to act immediately. On the battle grounds, he is annoyed by Katsuki's bossiness.

Hanta uses his tape to create a barricade so that the lizard parts cannot attack and proceeds to call Katsuki over.
