Tenya Ida/Synopsis

History
Born as the second son of the Iida Family, a family that has been in Heroics for generations, Tenya aspired to be like his big brother Tensei who became a famous Hero in his family. Tenya once asked his older brother what motivated him to be a Hero, to which Tensei replied that he wanted to be a 'cool' type of Hero that helps others when they are in need. When Tenya speaks of his admiration for his older brother, Tensei is joyful that Tenya looks up to him and says that he must be a great Hero since Tenya admires him.

Before attending U.A. High School, Tenya previously went to Soumei Junior High School, a prestigious, private school.

Entrance Exam Arc
Tenya Ida first appears at the U.A. High School Entrance Exams. In the auditorium before the practical portion, Tenya questions Present Mic about the four villains listed during the explanation. After Present Mic answers his question, Tenya yells at another participant, Izuku Midoriya, for muttering too much as he is being a distraction. Tenya later confronts Izuku just before the practical portion begins. He notices Izuku trying to talk to a female participant, Ochaco Uraraka, but stops him from ruining her concentration with him drawing more bad attention to Izuku.

Tenya manages to do very well during the test, scoring forty five points well into the exam by using his "Engine" Quirk. When the giant robot worth zero points shows up, Tenya flees the area despite noticing that Izuku was on the ground paralyzed with fear. He is soon shocked to see Izuku spring into action, where he saves Ochaco from the zero pointer bot by destroying it with one devastating blow.

Tenya is the only one among the viewing participants to notice that Izuku saved Ochaco. This leads Tenya to question the nature of the exam and ponders whether heroic acts had a part in the exam all along. He says to himself that he would have done the same if he hadn't been on the exam and that maybe it's part of the test.

Quirk Apprehension Test Arc
April arrives and the U.A. academic year begins. On the very first day in class 1-A, Tenya argues with Katsuki Bakugo over putting his feet on the desk. Tenya explains that this action is disrespectful to the school, but Katsuki doesn't care. Tenya tries to calm down and introduce himself properly, but Katsuki's only reply is that he'll simply crush him. Tenya is shocked that Katsuki would threaten his own classmate just as Izuku enters the class, surprised he is classmates with both Katsuki and Tenya. Seeing him, Tenya decides to re-introduce himself to Izuku instead. He apologizes for his previous treatment and commends him for seeing what he had not during the practical exam, that saving others was just as important as defeating the villains. Tenya even goes on to say that Izuku is the superior student.

Ochaco arrives and interrupts them by introducing herself to Izuku just before Shota Aizawa arrives and reveals himself to be class 1-A's teacher. Shota takes the students to the P.E. field for a Quirk Assessment Test. Tenya completes the fifty meter dash in 3.04 seconds, but questions why Izuku is struggling through them. When Izuku finally uses his Quirk, it shocks Tenya and the rest of the class with his impressive ball toss.

He notices that Izuku has barely trained with his Quirk, due to his finger injury. In the test, Tenya sees that he has placed 4th. Later on, he asks Izuku if his fingers had healed. He tells Izuku that Shota Aizawa can encourage students through deceptions to get the best out of a student. He then sees Ochaco Uraraka walk to them and remembers that Shota gave her an infinity score on the test. She calls Izuku "Deku," as Izuku tells them it's an insult Katsuki gave him as children, but changes his view on the name as Ochaco calls it cute, as Tenya is surprised at this change of mind. The next day, Tenya is seen wearing his hero costume.

Battle Trial Arc
During the arc, Tenya is teamed up with Katsuki Bakugo as the villains. Tenya complains that Katsuki left him alone to guard the fake Nuclear Bomb. He contacts Katsuki and asks about the situation, but Katsuki just tells him to guard the fake bomb and then hangs up, much to Tenya's annoyance.

While guarding the fake bomb, Tenya decides to act more like a villain. He takes his villain role so seriously that Ochaco can't help but laugh. This makes him realize that she is in the room, and says that he has been expecting her. He goes on to say that he is prepared to counter her Quirk by cleaning the floor and starts to laugh like a villain.

Suddenly, Tenya is distracted by Katsuki's Explosion, shocked by his action. Ochaco uses his distraction to her advantage and uses Skill Release to jump over Tenya to grab the fake bomb, but Tenya uses his Engine Quirk to quickly snatch the fake bomb before she could reach it.

The floor is destroyed by Izuku's Detroit Smash and Ochaco uses the opportunity to launch her Home Run Comet attack, which distracts Tenya long enough for Ochaco to grab the fake bomb, making Tenya and Katsuki lose the battle trial.

Tenya goes to the monitor room to have his critique. All Might says that the best participant in the battle trial was Tenya, which greatly shocks him. Momo Yaoyorozu, says that Katsuki and Izuku using large ranged attacks in an indoor area was too idiotic; Ochaco's game got loose halfway and her last attack was reckless.

She continues on to say that he was the best due to him adapting the most to the situation by organizing a counter strategy against his opponent that would allow him to protect the fake bomb the best way possible while hindering his opponent. Tenya can't help but feel enormously happy being praised in that way.

U.S.J. Arc
Tenya is approached by reporters, asking him what he thinks of All Might as a teacher, to which he replies that he's happy to have an impressive role model as a teacher. In class, Tenya says that a leader is only worthy from a democratic choice of the people's will and proposes a vote, to which is allowed. After the vote, he is disappointed to see that he didn't get any votes.

At lunch, Tenya assures Izuku that he will do a fine job as Class President, going on to say that he has guts and right judgment, which is why Tenya voted for him (even though he wanted to be Class President). After Ochaco asks if he's from an upper-class family, Tenya confirms that he is, telling Ochaco and Izuku that he's from the Iida Family, a prestigious family that's been in heroics for generations. He then reveals that Turbo Hero Ingenium is his older brother and aspires to be like him one day.

After the siren goes off, he gets pushed around during the evacuation, eventually pushed against the window, which he sees that the "infiltration" is just the media. Tenya decides to step up and stop the chaotic evacuation, asking Ochaco to make him float, allowing him to jump up into the air and then uses his Engine Quirk to sprint onto the exit sign, where he is finally able to tell everybody to calm down since its just the media, which stops the chaotic evacuation.

In class, Izuku decides to step down as Class President and makes Tenya his replacement, saying that he is ideally the right choice after stopping the chaos in the lunchroom to which everyone agrees. Thus, Tenya officially becomes the Class President of 1-A.

Tenya changes into his Hero Costume in preparation for the rescue training trial and orders his classmates to get into two lines according to numbers to get into the bus smoothly (although this turned out to be pointless due to the layout of the bus). Tenya is later seen applauding No 13's speech. However, before anything else could progress, the trail is interrupted by the arrival of a group of actual villains, much to Tenya's surprise.

Tenya tries to evacuate with his class, but their attempt is foiled when Kurogiri begins to separate the class with his warping ability. However, he manages to escape from the villain's ability, saving Ochaco and Rikido Sato in the process. They are further joined by Hanta Sero, Mina Ashido, Mezo Shoji and Thirteen, who all confront Kurogiri himself.

Thirteen asks Tenya to dash back to U.A. as fast as he could and inform the school of their situation. Tenya is at first reluctant to do so as it would be disgraceful to abandon his classmates, but after being encouraged by Rikido, Hanta, Ochaco and Thirteen, with the latter being taken down by Kurogiri, Tenya decides to run back to U.A., with Kurogiri in pursuit of the student.

As Tenya approaches the exit, he is intercepted by one of Kurogiri's portals, but Mezo Shoji distracts the villain long enough for Tenya to reach the exit, which he is forced to open manually, however, Kurogiri tries to stop him once again, only for his attempt to be foiled by a combined effort coming from Ochaco, Hanta and Rikido. With the villain finally being taken off his back, Tenya manages to escape the U.S.J. building.

Tenya, on his way to U.A., runs into All Might and tells him about the situation. Tenya manages to get to U.A. and gets the Hero some backup. He arrives back at the U.S.J with the Hero backup, just in time to save Izuku and All Might. Tenya is then seen with the rest of his class after the battle with the Villain Alliance ends.

U.A. Sports Festival Arc
Following the attack on the U.S.J. students continue their routines until the Sport Festival is about to start. Tenya and Izuku are surprised to see that Ochaco is the most excited for the event. After the fourth period of modern literature ends, Izuku and Tenya listen to Ochaco's motivations to be a heroine. She wants to earn money, noting that it is a selfish reason, but Tenya says that becoming a hero to make a living is not selfish at all.

Izuku and Tenya point out that Ochaco's Quirk could drastically reduce business expenses if she got licensed, and her family could sell their construction equipment as well. Ochaco agrees completely, but remembers that her father encouraged her as a child to follow her own dreams instead. Izuku and Tenya are genuinely inspired by Ochaco's noble ambition..

On the day of the Sports Festival, Tenya is seen walking out to the event with his class. During the Obstacle Race, Tenya manages to navigate past the robots. Afterwards, he heads towards the Fall, where he uses his 'Engine' Quirk to ride the tightropes in order to get to overcome the obstacle. Tenya later speedily avoids the hidden landmines as they explode.

He eventually manages to complete the Obstacle Race, placing sixth, allowing him to continue on to the next event, the Human Cavalry Battle. Izuku tries to have Tenya join him and Ochaco in their team, however, while liking Izuku's strategy, he politely declines his invitation to join his team.

Tenya states that, even though they are good friends, he feels that if he keeps following Izuku he will never grow. Tenya then says that he will be challenging himself against Izuku so that he can grow. Tenya is then seen teaming up with Shoto, Momo and Denki. Shoto explains that Tenya will be in the front using his Quirk to act as a physical defense. After the Human Cavalry Battle begins, Tenya and his team confront Izuku and his team.

Shoto orders Momo to prepare an insulator sheet and tells Denki to prepare to release his electricity. Shoto covers himself along with Momo and Tenya with the insulator sheet while Denki releases a huge amount of electricity, electrocuting and stunning the other teams attacking them. Afterwards, Shoto immobilizes the stunned teams by freezing their legs. Shoto takes one of the headbands of the teams while charging forward to fight Izuku's team. Fumikage's Dark Shadow tries to attack Shoto but Momo uses her Quirk to block the Dark Shadow. Shoto's team continues fighting but Izuku's team proves to be quite resilient.

With only a minute left, Tenya tells his team to hold on tight as he uses his move Recipro Burst to forcibly accelerate his movement to blazing speeds allowing him and his team to speed past their enemies in a blink of an eye which catches Izuku's team off guard and allows Shoto to grab Izuku's 10 million headband in the confusion. Tenya then explains his move but adds that he will suffer from engine stall for a short time, meaning he and his team are unable to move. He then says reminds Izuku that he is challenging himself against him. Izuku's team attack Tenya and his team. Unable to move, Tenya and his team are forced to fight Izuku's team for the remaining minute of the Human Cavalry Battle.

After Izuku manages to get a headband from Shoto, Tenya tells Shoto to pull himself together which snaps Shoto back to reality. For the last ten seconds, Tenya's team prepares to battle, but the Human Cavalry Battle ends before they could battle. Tenya's team places first, allowing him and his team to participate in the final event. After the lunch break begins, Ochaco talks to him about him being sneaky with his Recipro Burst move, but Tenya replies that he was not being sneaky and all he wanted to do was be a proper rival to Izuku.

The final event is a tournament event and Tenya's opponent in the first round is Mei Hatsume. Mei meets her opponent, asking if he is Tenya, to which he replies that he is. Mei gives Tenya some support items so that their fight can be on equal terms, which he accepts. During the recreational events, Tenya is seen drinking cool drinks to renew his energy. Tenya watches Shoto's match with Hanta, becoming shocked and horrified when Shoto creates a huge pillar of ice.

Tenya then faces Mei in his match with her, equipped with the support items and gadgets she gave him. After Midnight explains that students in the Department of Heroes need to apply for permission to use support items, Tenya apologizes for doing so, saying that he was moved by her superb sportsmanship for wanting to fight on equal terms and felt that not using her support gadgets would be dishonorable of him.

The match begins with Tenya running at Mei using his enhanced leg support item received from Mei, but Mei dodges him with her own equipment. For the next ten minutes, Tenya and Mei continue their fight with Mei explaining the features of her gadgets and items in the process. After ten minutes, Mei steps out of bounds and eliminates herself from the tournament, allowing Tenya to advance to the next round. Tenya is angered for being played like a fool, with Mei apologizing to him for doing so.

After winning his match, Tenya goes to the waiting room to relax, only to find Ochaco in the waiting room as well. After Izuku arrives and offers to give her notes on a strategy against Katsuki based on her Quirk, Tenya thinks that Ochaco must be pleased. However, Ochaco politely declines Izuku's offer, saying that she will be all right. Tenya, along with Izuku, go to their seats to watch Ochaco's match with Katsuki. Tenya asks Izuku what his counter strategy for Katsuki was, to which Izuku replies that the strategy involved striking fast to gain the advantage. Tenya watches the match and expresses worry for Ochaco when she gets hit repeatedly by Katsuki's explosions.

During the match between Izuku and Shoto, Tenya becomes shocked that Shoto is using his fire power despite him saying that he never would. After Shoto defeats Izuku, Tenya, along with Ochaco, Tsuyu, and Minoru, go to Kango's office to see Izuku. However, Tenya is forced to leave as Kango states that Izuku is going to undergo surgery.

Tenya faces his opponent, Ibara Shiozaki in his second round match. During the match, Ibara attacks Tenya with her thorns, but Tenya's maneuverability allowed him to avoid her thorns. In the remaining seconds of the match, Tenya uses Recipro Burst, grabs Ibara, and throws her out of bounds, thus making Tenya the winner and allowing him to move on to the third round (the semi-finals).

Tenya then goes to see Izuku and is happy to see that his surgery went well. After Tenya told Izuku how he defeated Ibara, he tells Izuku that he will make ample use of his match against Shoto. Izuku asks Tenya if his brother is watching, Tenya tells Izuku that he was, but is busy due to work. Tenya tells Izuku that he will report back to his brother as the victor of the tournament event. After Katsuki defeats Eijiro, Tenya tells Izuku he will be back and goes down to the ring.

Tenya faces his opponent, Shoto, in his third round match. After the match begins, Shoto attacks first with a wave of ice, but Tenya dodges the ice by jumping towards Shoto. While in the air, Tenya notes that now that Shoto is using his fire power, his options are very narrow, causing Tenya to think that his best option is using Recipro Burst to finish the match quickly.

Tenya uses Recipro Burst and tries to attack Shoto with a speed-enhanced kick, but Shoto dodges his kick. Tenya quickly counters and attacks Shoto with another speed-enhanced kick, which slams Shoto down onto the floor and injures him. Shoto grabs Tenya's leg, but Tenya kicks Shoto away. Tenya grabs Shoto and proceeds to try and throw Shoto out of bounds before Recipro Burst ends.

However, along the way, Tenya realizes that there is ice in his mufflers and he slows down. Shoto then freezes Tenya's entire body. Due to being unable to move, Tenya is declared defeated and is eliminated from the tournament event. Tenya is angry at himself for not thinking more about his opponent's tactics and apologizes to his brother for losing.

Tenya, along with Izuku and Ochaco, watches the match between Fumikage and Katsuki. After Fumikage surrenders, Tenya tells Izuku and Ochaco to watch the final match closely for their revenge later, to which Izuku and Ochaco agree. Suddenly, Tenya's phone starts ringing and excuses himself.

Tenya goes to answer his phone in private. Tenya picks up his phone, noticing that his mother is calling him. Tenya apologizes to his mother for losing in his match and that he was too careless. However, Tenya's mother tells him that she is not phoning about that, though she does apologize for his loss and tells Tenya to stay calm for her real reason. Tenya is shocked at the news his mother is telling him and becomes distraught. Tenya tells Ochaco and Izuku that he has to leave due to learning that his older brother has been cut down by a villain. Tenya leaves the Sports Festival and goes to the Hosu General Hospital where his brother is.

At the hospital, Tenya immediately barges into the room his brother is in and is shocked at Tensei's injuries. Tensei, despite being weak, tells Tenya that he is a brilliant little brother and apologizes to him for not being able to be the role model Tenya sees him as. Tenya begins to weep. Tensei tells Tenya that he can no longer feel any movement in his legs and says that this is probably the end for Turbo Hero Ingenium. Tenya refuses to believe this, unable to stand the idea. Tensei tells Tenya he cannot stand the idea either and asks him to carry on the torch and use Ingenium as his Hero name.

Vs. Hero Killer Arc
Two days after the Sports Festival, Tenya is running to U.A. and passes by Izuku, telling him that they should be at least 10 minutes earlier for school. After arriving inside, Tenya tells Izuku that he doesn't have to be worried about his older brother as he will be fine and apologizes for causing him unnecessary concern. During the Hero Informatics Period, Shota shows the students the Pro Hero nominations, which reveals that Tenya received 301 Pro Hero nominations to which Ochaco congratulates him.

Afterwards, Class 1-A has to decide on Hero names. Tenya and Izuku are the last ones to reveal their Hero names. Tenya struggles on whether to use his brother's Hero name, Ingenium or not. Tenya is unable to bring himself to write down Tensei's Hero name Ingenium and instead writes down and shows his classmates his own name.

After Class 1-A is finished formulating their Hero names, Tenya is given his personalized work place list to choose a work place that he wants to train at. Tenya chooses the Hosu City Hero Office to train at. The day of the work place training arrives and Tenya is at the train station with his class. As Tenya goes to board his train, Izuku tells Tenya that if he needs someone to talk to, he can talk to him and Ochaco (with Ochaco nodding in agreement) as they are friends. Tenya says that he will. He then walks away to his train with a scowl on his face.

Tenya arrives at Hosu City's office. In the borough of Hosu City, Tenya in his Hero costume goes on patrol with Manual. Tenya ponders that the Hero Killer Stain was the one who critically injured his older brother Ingenium, deciding that he himself will chase after Stain, unable to forgive the Hero Killer for his crime, declaring that he will avenge his older brother and kill him.

In the Hosu Hero Office, Tenya has arrived back from patrolling. Tenya has gathered information on the Hero Killer Stain, the villain who severely injured his older brother and realizes that Stain has an attack pattern. Tenya concludes that Stain will without a doubt be in Hosu to attack more Pro Heroes. Tenya, in a silent rage, tells Stain to appear so that he himself can dispose of Stain with his own hands.

It is the third day of workplace training and Tenya is out patrolling with Normal Hero. Normal Hero asks Tenya if he is chasing after the Hero Killer Stain, thinking that would be the only reason Tenya came to the Hosu Hero Office. He tells Tenya not to act out on a personal grudge. Normal Hero apologizes for his question to which Tenya replies that he appreciates his warning. However, Tenya ponders that if he doesn't get revenge, what should he do with his rage and emotions.

Chaos emerges in Hosu and Normal Hero, who at the time was patrolling with Tenya, tells Tenya to go with him. Suddenly, Tenya sees someone in an alley. he approaches closer and sees that it is the Hero Killer Stain. Tenya immediately charges at Stain. However, Stain takes his katana and slashes it at Tenya, knocking Tenya down to the ground as well as knocking off Tenya's helmet and glasses. Stain sees that Tenya is just a child and tells him to leave. Tenya gets up, seeing that the villain in front of him is indeed the Hero Killer Stain.

With a scowl on his face, Tenya tells Stain that he has been searching for him but didn't expect to meet him so soon. Stain points his katana at Tenya's face, telling Tenya that his eyes are seething with vengeance and warns Tenya not to meddle with him, otherwise even children will become targets. Stain prepares to walk away, but Tenya, seething with rage, yells at Stain that he is the brother of a Pro Hero that he cut down and he is here in his older brother's stead. Tenya tells Stain to remember his Hero name; Ingenium, which is the name of the Hero that will take him down. Stain sees that the child is serious and tells Tenya to prepare for death.

Tenya attacks Stain with a high speed kick, but the Hero Killer dodges Tenya's fast kick with ease by jumping above him. Stain kicks Tenya's right arm, causing it to bleed and slams Tenya onto the ground with his left foot. Stain stabs Tenya's left shoulder with his katana which defeats Tenya. Stain reveals to Tenya that he let Tensei live in order to feed rumors. Stain says that both him and his brother are weak because they are fake Heroes. Tenya, even though he is defeated, rebukes Stain's claim that his older brother Tensei is weak, yelling that Tensei was a splendid Hero and that he will kill Stain to avenge his older brother. Stain tells Tenya to save the injured Pro Hero behind him, advising the defeated younger brother to act selflessly by rescuing others first and not be selfish by brandishing his power for his own sake. Stain states that seeking revenge just to satisfy one's selfish desires is the act furthest from the title of "Hero" which is why he will die now.

Stain stomps his foot on Tenya's head and prepares to kill Tenya with his katana, licking the blood. Tenya tries to move his body but is unable to. Tearing up, Tenya refuses to believe Stain's advise, yelling that Stain is just criminal scum who hurt his older brother. Stain is about to deliver the finishing blow, but is punched in the face by the timely appearance of Izuku Midoriya, which stops Stain from killing Tenya, shocking Tenya.

Tenya orders Izuku not to get involved since his fight with Stain has nothing to do with him. Izuku responds to Tenya's order, saying that Heroes would not be able to do anything by following Tenya's logic. Tenya watches the battle between Izuku and Stain. After Izuku lands a powerful blow on Stain, Tenya is shocked at Izuku's fast movements, comparing Izuku's movements to Katsuki's. However, Stain managed to get some blood from Izuku when Izuku was dodging his slashes, causing Izuku to become immobilized. Stain prepares to kill Tenya once again, but suddenly, a column of fire and ice attacks Stain, forcing Stain to stop his attack on Tenya and dodge the fire and ice. Shoto reveals himself as the one that attacked Stain.

Shoto then proceeds to battle Stain. As their battle gets underway, Tenya begs Shoto to stop fighting, as he inherited Ingenium's Hero name. Shoto criticizes Tenya for making a vengeful face, saying that the Ingenium he knows would not make such a face. Izuku and Shoto team up to battle Stain, stating that they will protect Tenya. Tenya starts to feel regret for his actions as he has not been acting like a Hero should be. Stain paralyzes Izuku with his Quirk, causing a regretful Tenya to tell them to stop. Shoto replies that if Tenya wants to stop them he must stand up. As Stain breaks through his wall of ice, Shoto encourages Tenya to set his eyes on the person he wants to be. Tenya remembers that he wants to be like his brother, Ingenium and tries to break free of Stain's Quirk.

Tenya is ashamed that he needs protection from his friends, Izuku and Shoto. He then remembers his brother's motivation for being a Hero; that helping people is the best motivation for being a Hero. Tenya agrees with Stain; that he is a failure as a Hero and pales in comparison to Izuku and Shoto.

Stain's Quirk wears off and Tenya gets up with the motivation of not wanting to be outpaced as a Hero by Izuku, Shoto and his brother. Tenya uses Recipro Burst and smashes his leg into Stain's katana, breaking the katana in half. Tenya then kicks Stain away. Tenya apologizes to Izuku and Shoto for getting them involved in his problems, not wanting them to spill anymore blood for his sake.

Stain criticizes Tenya for having a change of heart, saying that a man's character never changes. Shoto tells Tenya to pay no heed to Stain, but Tenya says that Stain is correct about him not being a true Hero. Tenya tells Stain that he cannot give up so easily, as doing so means that Ingenium would die. Tenya asks Shoto to cool down his leg, but Stain attacks Shoto with daggers to which Tenya intercepts and falls down to the ground. Shoto cools Tenya's leg, restoring Tenya's mobility. Tenya uses Recipro Extend and leaps into the air towards Stain. He hits Stain in the stomach with his speed enhanced kick while Izuku punches Stain in the face with his enhanced might.

Stain makes one last ditch attempt to kill Tenya, but Tenya retaliates with a kick and Shoto shoots a stream of fire into Stain's face. Tenya and Shoto's additional attacks finally cause Stain to lose consciousness, defeating him. Tenya and Izuku land safely onto the ground thanks to Shoto's ice ramp. Shoto decides to tie up Stain with Izuku suggesting that they remove Stain's weapons.

Izuku, Shoto, Tenya and Native leave the alley with the unconscious restrained Stain in tow. Tenya offers to pull Stain but Shoto tells Tenya that his arms are in bad shape. After Gran Torino and Endeavor's sidekicks arrive, Tenya apologizes for his un-heroic actions with Izuku saying that he is also sorry for overlooking his pain, causing the speedy teenager to burst into tears; Shoto tells Tenya to pull himself together because he is the Class President, with Tenya complying. Out of the blue, the winged Nomu-like creature grabs Izuku; suddenly, Stain wakes up and defeats the winged Nomu-like creature while saving Izuku in the process.

After Endeavor arrives, Stain's bandaged mask falls off and reveals his true face, shocking Izuku. Stain walks forward and declares that the only one who is allowed to kill him is All Might, unleashing a bloody malefic aura in the process. Tenya falls to his knees out of fear, along with several other heroes. After Stain loses consciousness for the last time, Tenya becomes shocked that Stain is still standing. Tenya, along with Izuku and Shoto are taken to the Hosu General Hospital to have their wounds treated.

The next day at Hosu General Hospital, the recuperating Izuku states to Shoto and Tenya that it is a miracle that they are still alive as Stain could probably have killed them if he wanted to. Shoto praises Tenya for his bravery but Tenya admits that he doesn't deserve any praise. The Chief of Hosu Police, Kenji Tsuragamae arrives and tells Izuku, Shoto and Tenya that the Hero Killer is undergoing treatment. He states that Izuku, Shoto and Tenya acted on their own without the supervision of their superiors and as such violated the rules, thus they along with their superiors (Gran Torino, Endeavor and Manual due to their negligence) will be given punishment.

Shoto becomes furious that Tsuragamae expected them to follow the rules and let people die as a result. Izuku, Gran Torino and Tenya stop Shoto. However, Tsuragamae states that there were limited witnesses and as a result there will not be any punishment for Izuku, Shoto and Tenya but they won't be receiving any praise either from the public as the events that occurred yesterday will be covered up.

Tenya apologizes to Manual but Manual criticizes Tenya for his actions, asking him to never do it again. Tenya along with Izuku and Shoto thank the Chief of Hosu Police for not punishing them. Tsuragamae states that Tenya along with Izuku and Shoto have a promising future and thanks them for their heroic actions.

The next day of the newspapers publication of Stain's defeat, Izuku returns to the room where Tenya says his physical examination reveals that his left hand's fingers won't move properly, although a surgery will fix the damage. Tenya states that until he becomes a true Hero, he will leave his left hand in its injured state as a reminder of his un-heroic actions during the encounter with the Hero Killer; he will only undergo the surgery when he become a true Hero.

Izuku thinks that apologizing would have little effect and sees that Tenya realizes his mistake. Izuku says to Tenya that his hand is also like his; Izuku states that they must become stronger together to which Tenya agrees. Shoto apologizes causing Izuku to ask why; Shoto states that whenever he is involved, people's hands go bad. Tenya and Izuku are surprised that even Shoto can crack a joke but Shoto says he is serious, causing the three young Heroes to laugh together.

The workplace training comes to an end and Tenya returns to U.A.. In Class 1-A, after Denki makes a remark about the Hero Killer, Tenya says its fine because he understands if people find the Hero Killer "cool" due to his convictions. However, Tenya criticizes the Hero Killer for advancing his conviction with a purge which eventually led to his downfall. Tenya declares that he resolves to become a Hero anew in order to not follow the wrong path, causing Izuku to smile.

Later, Tenya along with Izuku, Ojiro, Mina and Hanta are the first group to partake in the Rescue Training Race. Tenya manages to finish the race despite his injury and worries about Izuku, who fell. After the race is finished, Tenya is in the boys' locker room and has changed into his school uniform.

When Minoru finds a hole in the wall and decides to peep through it to see the girls' locker room, Tenya reprimands Minoru for his behavior. After school is finished, Tenya is seen walking home with Ochaco and Izuku.

Final Exams Arc
One week before the end of term test, Tenya, who is revealed to have scored second on the midterms, encourages Denki and Mina to do their best. His words are joined by Izuku and Shoto, which unintentionally makes Denki and Mina feel even worse about their low scores.

In the lunchroom, Izuku, Tenya, Shoto, Ochaco, Tsuyu, and Toru, while eating, talk about how they will perform in 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 in their exercise test. Tenya is paired with Mashirao and must face Powerloader in their test exercise.

Tenya, Mashirao, and Powerloader arrive in an at a dirt field where their test exercise will take place. Powerloader explains the 30 minute test; Tenya and Mashirao must either handcuff him or one of them must escape the battlefield within 30 minutes in order to win and pass the test. The test begins.

Because Power Loader is constantly digging through the ground, Tenya and Mashirao can barely move because the ground collapses in front of them. Tenya decides their best course of action would be to escape. Mashirao gets on Tenya's back. Tenya activates Recipro Burst and outruns the traps. When the ground in front of him collapses, Tenya leaps over it.

Mashirao wraps his tail around Tenya's leg and the latter uses Recipro Extend to send Mashirao towards the escape gate, avoiding Power Loader's attempt to stop them. The team passes the practical test.

Back in class at U.A., Tenya learns that he passed the written test and will go along with his classmates to the forest lodge which is a boot camp. After Shota informs the class that the consequences for failing was a logical ruse, Tenya speaks up about his logical ruses causing them to lose trust in him; Shota admits that using logical ruses is a mistake and will reflect on it.

Later, Tenya, along with his class, goes to Kiyashi Ward Shopping Mall to buy necessities for the forest lodge. Izuku is confronted by Tomura Shigaraki in the Shopping Mall, who later leaves without hurting him. After Tomura leaves, Tenya hears what happened and rushes to Izuku, asking his friend if he is alright.

The next day after the shopping trip at U.A., Shota informs Class 1-A that the destination for their lodge trip has been changed and the new destination will only be announced on the day of the event. The first semester has come to a close and summer break has begun.

A day prior to summer break, Izuku invites Tenya and all the boys of Class 1-A to the pool for endurance training. The boys take a break after a intense training lead by Tenya. During which, Izuku and Tenya remember their path to becoming friends with one another. Katsuki abruptly arrives and challenges Izuku to a fight. Izuku refuses, but Tenya decides to hold a competition to see who can swim the fastest. Izuku swims and uses his Quirk to defeat even Tenya who uses his Recipro Burst technique. After finishing, they both notice Shoto Todoroki. All three of them once again vow to become the heroes they wish to be. The final race between Izuku, Katsuki, and Shoto is about to start, with Tenya as the referee. Before they can begin, though, Shota arrives and kick all the students out of the pool area.

On the day of the event, Class 1-A boards a bus that will take them to the forest lodge destination.An hour later, Class 1-A’s bus stops for a restroom break. There, they meet Pixie-Bob and Mandalay, two members of the Wild, Wild Pussycats, 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, which they must traverse to reach their destination.

Suddenly, Class 1-A are confronted by a beast; Koji tries using his Quirk to control the beast but it does not work due to the beast being made out of dirt. Tenya, along with Shoto, Katsuki, and Izuku, mobilize and use their Quirks to destroy the dirt beast.

Class 1-A begins traversing the Beast's Forest, destroying any dirt monster that faces them. However, the journey through the forest to the Cabin takes around about eight hours. Class 1-A arrive at the facility, battered and tired. Pixie-Bob admits that she thought they would take longer to get to the facility; she praises Class 1-A for figuring out her Earth Beasts quickly and easily.

She points out that Izuku, Shoto, Tenya, and Katsuki did especially well for taking quick action against the first of her Earth Beasts and concludes that they have experienced action against villains. After Kota punches Izuku in his crotch, Tenya goes to check on Izuku and admonishes Kota for his actions. However, Kota harshly replies that he doesn’t want to be with wannabe heroes and Tenya is taken aback by Kota's lack of respect.

Class 1-A fetch their luggage and put it in their rooms, Class 1-A head to the dining hall and have dinner; they enjoy the delicious food that the Pussycats provide them. After finishing dinner, Class 1-A goes to the hot springs. At the hot springs, Tenya orders Minoru to stop with his perverted ways, but Minoru ignores him and begins scaling up the wall, only to fall down courtesy of Kota.

The next day at 5:30 AM, Class 1-A is seen outside the training camp cabin. Shota greets his students and tells them that they will undergo reinforcement training to strengthen and upgrade their Quirks. Tenya's training consists of doing long training runs to increase his leg strength and stamina. That night, after the students are tasked with making curry for dinner, Tenya sees this as survival skill training and motivates the students to make the most delicious curry in the world.

After another day of intense training, Tenya prepares to participate in a courage test organized by the Pussycats. However, before he has the opportunity to participate, the Vanguard Action Squad of the League of Villains invade the place that night, attacking the students and tutors. One of them, Spinner, is a devotee of Stain's ideals and recognizes Tenya as the one who brought Stain's terror to an end, and unsheathes his sword as he claims to make Stain's dreams a reality. Mandalay decides to deal of him, she tells the Class 1-A students who are not participating in the test to leave and orders Tenya to take the lead. As Tenya leads his classmates away, Izuku Midoriya tells Tenya to go on ahead as he informs Mandalay about the villains' objective.

Tenya Ida, along with Mashirao, Minoru, and Koji, arrive at the facility, where they see Shota holding Dabi, who disintegrates after receiving great damage. Shota orders the students to go into the facility, while he heads into the forest himself.

Once inside, Tenya and the rest wait until they receive a telepathic message from Mandalay, in which she says that Shota has authorized the students to use their Quirks to defend themselves. Eijiro asks Vlad King to allow them to fight, and Tenya supports him, saying that not knowing how many enemies there are, it would be better to have as many people fighting as they can. Vlad King refuses and prevents the students in the building from fighting, explaining that only the students in the woods have permission to fight with Quirks because they need to defend themselves. At that moment, they are attacked by a copy of Dabi, but Vlad protects them and quickly defeats the copy. Shota arrives and destroys the clone of Dabi, saying to Vlad King that the villain is only aiming to distract the pro-heroes.

Despite the efforts of the teachers and students, the League manages to kidnap Bakugo, and leave the forest, leaving several students injured.

Two days later after the League of Villains' attack on the training camp is over, Tenya visits Izuku who is in hospital. Tenya informs Izuku about Toru, Kyoka, and Momo's conditions. After Eijiro and Shota explain about a transmitter being planted on a villain by Momo and Yosetsu, Tenya deduces that Eijiro wants Momo to create a device for themselves so that Class 1-A can track down and rescue Katsuki themselves.

Tenya demands that the rescue of Katsuki be left to the Pro Heroes, but Eijiro is tired of being unable to do anything that will make him a Hero and a friend, causing them to get into an argument. After being calmed down by Denki and Tsuyu, although fully aware that the matter should be dealt by professionals, Eijiro encourages Izuku to go through with the plan as it will allow him to reach and save Katsuki. Izuku gives Tenya a pleading look, but Tenya is hesitant as he knows fully well about the consequences they will face.

Hideout Raid Arc
Like Tenya, most of Class 1-A are hesitant about attempting to rescue Katsuki. Tenya leaves Izuku's room and overhears Eijiro telling Izuku about going through with the rescue plan tonight.

Later that night, Tenya appears before Izuku, Shoto, Eijiro, and Momo. Tenya is angry that they are about to repeat the same mistake he made at Hosu. Despite Izuku knowing that breaking the rules is against the law, Tenya punches Izuku in the face. Frustrated that they are not taking his concerns, feelings, and worries into consideration; Tenya says that he doesn’t want to see Izuku or any of them end up with severe injuries.

Shoto tells Tenya that they will not engage the villains in combat while Eijiro states that their rescue will be covert. Momo states that she came along to accompany them all in order to prevent them from engaging in combat. Izuku tells Tenya that after failing to save Katsuki at the training camp, his gut feeling is telling him that he must save Katsuki. Tenya sees that they are determined and resolute and is cheered up by the fact that they won’t engage in combat; Tenya decides to go with them.

Tenya, along with Izuku, Shoto, Momo, and Eijiro, board a train to travel to a place called Kamino Ward, a place in Yokohama City in the Kanagawa Prefecture. At Kamino Ward, they put on disguises to make infiltration easier as well as to prevent the League of Villains from recognizing them. The disguised group exits the clothing shop and observes a video clip of U.A.'s public apology.

They continue towards the place that Momo's tracking device is detecting. After waiting for a while near the place, Momo notes that the villains have made no movements and states the possibility of Katsuki not being in the place while Tenya reminds them that if he sees any combat, then he will not hesitate to stop them. Izuku thanks Tenya Afterwards, they prepare to infiltrate the supposed League of Villains’ hideout; Tenya, although he respect Izuku's determination, will not hesitate to stop Izuku if there is combat because it is his turn to protect him.

Tenya and the others go to the back of the hideout and see a window. Shoto and Tenya have Izuku and Eijiro stand on their shoulders to see what is inside using the night-vision goggles Eijiro brought along. Mt. Lady destroys the front of the warehouse which shocks Tenya.

Seeing that the Pro Heroes are at the warehouse, Izuku and the group assume that All Might is with Katsuki as they are speaking. Izuku and the group decide to head home. Suddenly, the entire warehouse is completely destroyed by a man along with the surrounding area being significantly damaged.They are paralyzed by fear due to All for One's overwhelming presence. Izuku attempts to move in order to save Katsuki who was teleported to their location. However, Tenya stops Izuku from making his move, serious in his resolve to protect Izuku and the rest of the group.

As the battle between All Might, All For One, Katsuki, and the League of Villains continues, Izuku comes up with an idea. Tenya tries to oppose, but Izuku says that the plan won’t involve fighting and that it will enable them to rescue Katsuki and escape. However, the entire plan rests on Eijiro because Katsuki will respond to him due to the friendship they have built up during their time at U.A.. Tenya understands that the plan is a gamble, but considering the situation, there won’t be much risk due to All Might’s presence.

Izuku puts his plan into action; Izuku and Tenya hold onto Eijiro with Izuku using One For All Full Cowl and Tenya using his Recipro Burst to burst through the wall while Eijiro uses his Hardening to protect himself, Izuku and Tenya. After Izuku, Tenya and Eijiro burst through the wall, Shoto creates an ice ramp. Izuku Tenya and Eijiro jump off Shoto’s ice ramp and head into the sky.

All For One sees the trio and attempts to attack them, but All Might intervenes by knocking him out. Katsuki sees the trio while Eijiro yells at Katsuki to take his hand. Tomura tries to take himi, but Katsuki uses his Explosion to launch himself towards Izuku, Tenya and Eijiro. Katsuki grabs Eijiro’s hand and smiles.

Kenji and Spinner launch Mr. Compress into the air, but Mt. Lady intercepts him, allowing Izuku along with Eijiro, Tenya and the rescued Katsuki to get away. Izuku, Eijiro, Tenya and Katsuki land on the ground far from the battlefield and begin escaping.

Tenya along with Izuku, Eijiro and Katsuki reach the front of the train station and watch the battle between All Might and All For One unfold, cheering for the former to not give up. After All Might defeats All For One, Tenya along with Izuku, Eijiro and Katsuki meet up with Momo and Shoto. They take Katsuki to a Police Station for his safety. Afterwards, Tenya goes home.

Provisional Hero License Exam Arc
Following Bakugo’s rescue and the retirement of All Might, Nezu transformed U.A. into a boarding school in order to protect the students. The Height Alliance was built in just three days. Shota Aizawa 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.

Then, Shota scolds Tenya, Izuku, Momo, Eijiro, and Shoto, revealing that he knows that they were present at the site of Katsuki Bakugo's rescue and took it upon themselves to rescue him. He also knows that the rest of Class 1-A, except Katsuki, Toru, and Kyoka, also knew about their plans, but did nothing to persuade them. He then says he would have expelled everyone but Bakugo, Hagakure, and Jiro from the school if it weren't for All Might's sudden retirement. Shota advises the group that went to save Katsuki to go through the proper procedures next time which will also restore the trust between them.

Class 1-A arranges 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 Mina Ashido suggests a room showcasing competition. When they check out Tenya’s room, it is full of books, and is inhumanly neat. He also has entire shelves full of spare glasses, which Uraraka finds it hilarious. Tenya states that it is because he expects them all to be destroyed during training.

After the competition, at Ochaco's urgings, Tenya, along with Izuku, Shoto, Eijiro, and Momo, heads outside the dorm where they find her with Tsuyu. Tsuyu apologizes for harshly doubting their plan to save Katsuki, and they apologize for worrying her.

The next day, Class 1-A begin their school life anew. In Class 1-A's room, Shota Aizawa mentions that their first objective will be earning their "Provisional Hero Licenses". To prepare for the Provincial Hero License exam, Class 1-A students will create at least two signature Super Moves that they will use in combat, with his help and that of Cementoss, Ectoplasm, and Midnight. They mention Tenya's Recipro Burst as an example of a special move, claiming that it poses enough threat to be classified as one, much to Tenya's delight.

Following the recommendations of Shota, Tenya, Izuku, and Ochaco head to the Development Studio for a costume upgrade. Tenya wants an upgrade to his radiator to help keep his engines cool. There, they meet again with Mei Hatsume, who causes problems to the three students with her inventions. When Tenya asks Power Loader for cooling capabilities for his legs, Mei gives him arm engines, sending him into the ceiling. Mei's argument in favour of this baby is that Tenya can run with his arms while his legs cool off. Mei's suggestion makes Izuku realize he can use his legs for combat if his arms are so vulnerable to excessive use of One For All. He asks Tenya for advices on how to use the legs for combat. Tenya's advice allows Izuku to develop One For All: Full Cowl - Shoot Style.

On the day where the Hero Qualification Exam starts, Class 1-A arrive at the test location, along with several other classes from other hero schools. Shortly after the exam starts, the first part of the exam involves thinning out the amount of people who can succeed by playing a game, where people put three marks on their body and are given six balls to throw at the other examinee's marks. Those whose marks have been hit are disqualified.

As the exam starts, the students of the other schools focus entirely on U.A. Thanks to their training and costume upgrades, Class 1-A manages to avoid being hit by the 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.

After Class 1-A gets scattered after the customary Crushing of U.A., Tenya decides to go after his classmates. While searching for them, Tenya happens upon Yuga hiding by himself. Tenya explains that he's already found some of Class 1-A and he's trying to have all of them regroup. Yuga proposes that they might have already passed while Tenya is searching. As the class president, Tenya would be happy for his classmates if that were the case. He asks that he and Yuga work together to pass.

However, they find themselves in the middle of several students from different schools ready to take them out. As Yuga thinks that the situation is bad, Tenya saves Yuga from a stray bullet and tells him not to give up. Tenya tells Yuga that as long as he is able he will do his best to serve his class, just as his brother would do and that his actions follow his dreams. Inspired by Tenya's self-sacrifice, Yuga shoots his navel laser upwards. He already has two of his targets lit up and does not want Tenya to go down with him, so he decides to use himself as bait to draw in the enemy so Tenya can hide and ambush them. Yuga explains that he's always wanted to be equal.

Enemy students arrive, but just before they attack Tenya, all the remaining 1-A students make their way towards them. One by one, Class 1-A students manage to defeat the other students and successfully passes the first phase of the exams. Tenya and Yuga run to their targeted opponents and Tenya tells the latter that no matter who he wants to be an equal with, he's the beacon that allowed Class 1-A to succeed. They eliminate their last targets to fill the final two spots for the first phase, annoucning the end of the first phase.

The second phase of the exam begins and the students are expected to rescue H.U.C employees who will act as victims. Tenya notes that the disaster site may be modeled after Kamino and tells Izuku that while they had been focused on rescuing Katsuki and avoiding combat there had been many casualties that day. As the second phase begins Tenya sticks with the rest of his class and manages to pass with 80 points, receiving his provisional license. He pulls Minoru away from Shoto as the former had begun taunting Shoto for his failure to pass the exam.

Shie Hassaikai Arc
The night after the exam, Izuku and Katsuki have a fight, so they are punished by Shota Aizawa. The next morning, classes resume and the rest of Class 1-A learns of Izuku and Katsuki's bout. Tenya feels disappointed with them and tells them that they have been lucky that they got off the hook with house arrest for a few days only, cleaning the dormitory common spaces day and night, and that the rest of Class 1-A will attend the opening ceremony without them.

The next day, after the classes, Izuku overhears some of Class 1-A talking about Hizashi's new grammar lessons and the Hero Work-Studies. Izuku feels that he has been left behind due to his house arrest punishment. Izuku tries to ask Tenya about the Hero Work Studies, but he refuses to share any information due to his misbehavior, stating that the class was told by Aizawa to not tell Izuku or Katsuki anything. Izuku's house arrest ends after three impatient days.

In Class 1-A, Izuku apologizes to the whole class for the inconvenience he caused and tells Tenya that he is sorry for disappointing him, which Tenya accepts. Shota arrives, and says that they will now go into more detail about the Hero work-studies. He brings in top three students of the U.A., who have experience with the Hero program: Mirio Togata, Tamaki Amajiki and Nejire Hado, also know as The Big 3.

Despite being considered the top students, their personalities confuse Class 1-A, who get even more 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. Izuku takes the initiative, but his kicks phases clean through Mirio's head. Using his Permeation Quirk, Mirio easily defeats more than half of the entire class 1-A. The other half tries to counterattack, Deku having discerned the functioning of his Quirk, but still Mirio also defeats them with hardly any problem.

As Class 1-A recovers, Mirio states that the reason he wanted to fight Class 1-A is to show the experience he gained from the Hero Internships; Mirio was able to transform his Quirk and reach the top. Class 1-A start seeing that Hero Work-Studies are different from the Field Training they went through.

During lunch a few days later, Tenya and Shoto notice Izuku is stressed out from some troubles in his internship. Both attempt to cheer him up, with Iida even using the same words Midoriya used for him before their Hero Agency Internships months ago. Tenya reminds Izuku that he can always talk to his friends and the latter tears up. Izuku wipes away his tears and claims heroes don't cry, and thanks Tenya for his support; Tenya's words have made Izuku's heart a little lighter. Shoto thinks that even Heroes must cry, and he and Tenya offering some of their food to Izuku.

During this period, some time after Tenya passed the Provisional Hero License Exam, he visits his brother Tensei while he is recovering in hospital. Tensei mentions to Tenya that it might be time for his engine's "tuning". Tensei tells Tenya that in the Iida family, "tuning" of the engine involves removing the mufflers that exit from the calves, which incurs an extreme amount of pain. After a while, improved mufflers grow in, allowing for increased performance.

Remedial Course Arc
Izuku, Eijiro, Tsuyu, and Ochaco are involved in a villain incident on their jobs with different hero offices, participating in the rescue of a girl named Eri, mission that ended in success but in which the League of Villains escaped with a powerful drug and Deku's Hero Work-Studies tutor died. They had to go through a bunch of inquiries and processes and heal from their wounds before being able to return to Heights Alliance.

When they finally arrive, the entirety of Class 1-A greet them, glad that they are alright, checking to make sure they are doing okay, physically and mentally, after their mission. Tenya Ida tries to calm down the class and asks them to be sensitive towards their feelings after everything they went through. Izuku thanks him for thinking about their feelings but he insures he is fine. Tenya accepts Izuku's opinion, and then "explodes", showing that he is worrying the most.

Days later, Tenya is seen along side Uraraka complimenting Izuku for his effort and dedication to his studies, he then invites Izuku and Aoyama to lunch to which the latter refuses.

U.A. School Festival Arc
At U.A. High School, Shota Aizawa announces that U.A. High School will be having a school festival and explains that the festival is sponsored by the other departments such as the General Department. However, Shota points out that part of the festival will be within U.A. and tells Class 1-A to pick out a program to perform at the festival. Tenya Ida asks ideas from Class 1-A; all of them give creative ideas, but they can not come to any agreement, so Shota tells Class 1-A to make a decision by tomorrow otherwise the class will be doing a public lecture.

Back at Heights Alliance, Tenya believes that Class 1-A should do a program where everyone can blow off steam. Finally, they decide to choose the Mina's idea of a dance, combining it with other suggestions. In the end, Class 1-A decides that their school festival program will be a live performance and dance with party space.

One day later, Tenya Ida is busy helping plan Class 1-A band and dance performance that is due a month later. Class A-1 students are divided into three groups, Band team, Staging Team and Dance team, with Tenya being part of the Dance team. The dance team constantly practice the choreography devised by Mina until the festival.

On the day of the School Festival, Tenya along with the rest of Class 1-A get worried as Izuku is late to show up for the performance. He manages to make it just in the nick of time. The performance is a resounding success and Tenya is showed doing the robot.

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, Tenya is placed with Mashirao, Mezo Shoji and Shoto, and they will face Class B's team of Pony Tsunotori, Sen Kaibara, Juzo Honenuki and Tetsutetsu Tetsutetsu at Round 3.

After Momo's group lost, Tenya's group waited for their turn as repairs were made to the area for their turn. Before his team headed out into the arena, Tenya catches Shoto's attention when he is lost in thought and relates to him on representing his brother, Tensei. Tenya briefly reflects on his brother's recovery from the hospital before telling Shoto they have to do their best as the latter agreed and they went out to battle. As the two teams get ready to start, Tenya watches as Shoto tells his team that their opponents will likely turn this into a head-on battle.

Tenya and the rest of his team run towards their opponents, who are still unsure of what move the 1-A team will make. Shoto blasts them and freezes all four of the Class 1-B students with a Giant Ice Wall. After Shoto's attack, Tenya uses Recipro Burst to run towards Tetsutetsu after waiting for the ice to slow down his movements. However, Juzo is able to free his team from Shoto's ice using his Softening Quirk.

Released from Shoto's ice, members of Team B attack Class A. Tenya tries to escape, but finds himself trying to run on top of pipes that Juzo has softened. Tenya loses his footing and falls into the frozen ground, which also was softened and turned into mud pit. Juzo claims Tenya is hard to deal with so he allow him to sink and re-harden the ice around him, trapping him. Juzo claims it was foolish for Tenya to use Recipro Burst so early in the match. Tenya argues that Juzo is underestimating him and activates his upgrade technique: Recipro Turbo!.

Thanks to Tensei's advice gave him short after Provisional Hero License Exam, Tenya tuned his engines to increase his horsepower while decreasing fuel consumption. Now Tenya can go beyond his limits for ten minutes. However, Tenya can't quite control himself and doesn't land a clean hit on Juzo. Even so, Juzo retreats by softening the ground into a liquid and swimming away within it. With Juzo out of the picture for now, Tenya moves out to find his other teammates.

First help Mashirao, who is having problems dealing with Sen and his Gyrate Quirk. Before Sen defeats Mashirao, Tenya speeds past, capturing Sen and running off to put him in jail. Sen is upset with Tenya for interrupting one-on-one fight, to which Tenya replies that his brother would have done the same, and that if he is to do this in the real world as a Hero, he must do it in training too. Tenya knows that saving people is more important than defeating the enemy.

Elsewhere, Tetsutetsu fights against Shoto. Although Shoto begins to use increasingly hot flames to get rid of him, Tetsutetsu keeps attacking and pressuring him, despite showing symptoms of fatigue and risk of melting. Shoto is about to perform a counterattack when Juzo interrupts their fight and softens the ground so that Shoto sinks, then hardens the ground once again after debris falls on Shoto, trapping him.

Shoto slowly loses consciousness but, out of the blue, Tenya appears and delivers a powerful kick to Juzo's head, destroying half of his mask. Tenya apologizes to Shoto for being late and carries his unconscious body away. Tetsutetsu says that he won't let them get away. Tenya has a flashback to the time he fought Hero Killer: Stain along with receiving wisdom from his brother. He yells that he will abstain from villains and that saving comes first.

Juzo laments allowing Tenya to run freely and resolves to make up for his mistakes. Juzo refuses to let his team lose because of his mistake, and softens a large metal tower before yelling to Tetsutetsu to push it over. Tenya tries to run away at full speed while carrying Shoto, but both get crushed by the building and get knocked out. At the same time, both Juzo and Tetsutetsu also collapse and are out cold.

Four competitors are down. Shoto, Tetsutetsu, and Juzo are all unconscious and Tenya trapped. He attempts to break free from the softened substance but can't due to his limbs being trapped under the tower. Tenya regrets not having been able to arrive earlier to help Shoto. Meanwhile, Vlad King comments on how Sen Kaibara's efforts to slow down Tenya during the match was effective enough to halt his progress

The battle continues with the remaining members of both teams, ending in a tie after Pony captured Mashirao and levitates herself high above the field with her unconscious teammates until time runs out. Everyone is taken to Recovery Girl's office and post-match critique is slated for later. Ochaco feels sorry for Tenya but Izuku claims he did very well in the battle.

At the office, Tenya apologizes to Shoto and says they could've won if he had been faster, but Shoto claims he was the one who slowed the team down and reflects on overusing his ice power compared to his flames. The two students vow to become Heroes who can put everyone to ease and rush to anyone who needs it. Juzo interrupts their chat and admits the flames and Recipro are hard to deal with. He wants to practice and asks both his rivals for a rematch. They agree and Recovery Girl kicks them all out of her office.

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. Tenya is in the office taking request when Momo tells him that one of the neighbors, Mrs. Sato, has suffered a sprain. Tenya immediately leaves to help the elderly woman and quickly takes her to the island hospital.

At night, all Class A members mention that despite they only did minor deeds, this kind of hero work is still hard, even though they're not fighting anyone. However, the island citizens are thankful, and they bring a bunch of food for the kids to eat at the Hero Agency. Tenya asks some of his classmates for some decorum due to their excitement over food, and thanks the neighbors for their supplies.

The next day, while Tenya 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, Shoto, Hanta, Rikido and, Fumikage will intercept the villain at the beach as Ochaco and Koji 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. 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. Shoto wants to chase him, but Tenya stops him by saying that if they couldn't defeat him outnumbering him, trying to face him alone is very dangerous, plus they must prioritize population safety

At night, the students retreat to a factory to heal their wounds and provide first aid to the inhabitants of the island. Tenya helps refugees and reassures them by ensuring Class 1-A protect them from villains. Later, they 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 next morning, Nine and his crew arrive at the entrance to the island. When the students see the villains approaching, they put their plan into action. Yuga Aoyama and Momo Yaoyorozu start attacking them from afar with their respective Quirks at full power. While Nine blocks the attack with his Air Wall Quirk, his allies break away from the blast. Chimera runs dodging the cannon shots, but a shot explodes near him and launches him off a cliff, though he lands unscathed near a waterfall. Here, Tenya, Shoto, Eijiro, and Tsuyu ambush him

Along with Eijiro, Tenya attacks him with a series of kicks and punches but Chimera blocks all his attacks easily until he feels his body funny. The students reveal that Tsuyu has covered their arms and legs with a special toxic mucus that she had secreted with his Frog Quirk. Chimera uses his quirk to transform himself, becoming bigger and more powerful and nullifying the toxin, and start attacking the four students.

Pinned by Chimera, Shoto devises a plan: they need their companions to distract the villain and help him get closer to him so that he can use his Ice powers at full potential to freeze Chimera. All of them agree to put the plan into action. Chimera manages to defeat Tsuyu, Eijiro and Tenya, knock them out, but thanks to their efforts the plan works, and Shoto freeze the villain before passing out from the cold temperatures in his body.

While they are unconscious after the battle, 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 for the next two weeks, Class 1-A continues to stay on Nabu Island to help repair the damage done by Nine and his villains until the Public Safety Commission suspends the program and orders them to be sent home. With the island being repaired by the military and the heroes, Class 1-A boards a ferry to return to the U.A. High School.

Paranormal Liberation War Arc
Winter break ends and students return to the U.A. to show their progress with their Quirks and skills. In Class 1-A, Tenya declares a happy new year to his classmates and that for today's class, everyone is to give practical reports on their Work-Studies and to be prepared to share what they gained from their experiences at Ground Alpha.

Shota comes in and tells everyone to get moving, and Tenya declares he did what he asked him to brief the class. Denki comments that Tenya is acting all fired up to which Tenya responds by saying his Work-Studies with Manual made him more flexible, though his energetic delivery causes everyone to comment how fired up he really is.

At Ground Alpha, under the supervision of All Might, Tenya show his skills fighting Villain Bots, and proclaims he improves his mindset during his Work-Studies with Manual. Later at night, Tenya helps his classmates to organize a Work Study/Brainstorm/Hot pot party to energize everyone for the new term. While enjoying food and socializing, Tenya reminds everyone that there are three months left for the final exams, and that they shouldn't relax too much. Mineta protests to Iida that his constant reminders ruin the taste of the hot pot.

The weeks pass until it's late March. The Hero Public Safety Commission had uncovered the plans of Tomura Shigaraki and his organization, the Paranormal Liberation Front. They organize a large force of heroes to take the villain organization down. While a team of heroes raid the Front's main headquarters, another team do the same at the Jaku General Hospital, where the Nomu are created.

Tenya, as well as several of her classmates, is part of a third group tasked with evacuating civilians from a city near the hospital, led by Burnin. The evacuation of the city proceeds without any problem, although Tenya wants to be sure that everyone is safe. He suggests to his teammates that they should check each building to ensure nobody has been left behind in senior homes and apartments.

Suddenly, the hospital and the entire area around it begin to falling apart, and the disintegration spreads rapidly until it reaches the city itself. Despite the efforts of some of his classmates to stop it, the destruction continues to spread, so the students run to safety taking all the citizens who were still there.

After evacuating the civilians from the site of the battle, Shoto ran away to aid his classmates and the Pro Heroes fighting Tomura. He notes that he can't contact them and Froppy says that the comms aren't working in some areas. Suddenly, the news report that a huge villain is making his way through many cities, with no heroes to stop him.
