Tenya Ida/Synopsis

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

Entrance Exam Arc
Tenya is first seen asking Present Mic a question about the 4 villains listed on the handout for Plus Ultra. He then notices Izuku shaking and tells him to sit still. Later on, he sees Izuku walking toward Ochako Uraraka and thinks that hes going to measure her power of concentration. Tenya grabs Izuku's shoulders and ask who he is and if hes going to obstruct another test taker. In Plus Ultra, he can be seen having 45 Points from villains hes defeated with his quirk "Engine" and then running away from the arena trap. When he sees Izuku's strength when he punched the arena trap, he is shocked to see that he had that much power. Later while everyone is looking at the damage, Tenya is the only one that notices that Izuku did that to save Ochako. He says to himself that he would have done the same if he hadn't been on the exam and that maybe its part of the test.

Quirk Apprehension Test Arc
Tenya is first seen arguing with Katsuki Bakugou about putting his feet on the desk. He asks him if he thinks its disrespectful to his classmates. Katsuki responds by saying no and asks what middle school he went to. He then tells him he previously attended Soumei Junior High School. Katsuki then says he has a reason to end him. Tenya, surprised, then asks him does really want to be hero. He then sees Izuku Midoriya and walks over to greet him. He then tells him that he was better than him in the Entrance Exam.

During the first trial of the Quirk Apprehension Test, 50 Meter Dash. Tenya completes the trial in 3.04 seconds. Throughout the fifth trial, Tenya questions about Izuku not doing so well.

he notices that Izuku has had training with his Quirk. In the test, Tenya sees that he has placed 4th. Later on, he goes to ask Izuku if his fingers had healed. He tells Izuku that Shouta Aizawa can encourage students through deceptions to get the best out of a student. He then sees Ochako Uraraka walk to them and remembers that Shouta gave her an infinity score on the test. She calls Izuku "Deku", and Izuku tells them its insult.. The next day, Tenya can later be seen wearing his hero costume.

Battle Trial Arc
During the arc, Tenya is teamed up with Katsuki Bakugou 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 then sees Ochako and says that he has been expecting her. He goes on to say that he 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. Ochako 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 Ochako uses the opportunity to launch her Home Run Comet attack, which distracts Tenya long enough for Ochako 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 continues on to say that he was the best due to him adapting the most to the situation by organising a counter strategy against his opponent that would allow him to protect the fake bomb the best way possible while hindering his opponent.

Unforeseen Simulation Joint 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 judgement, which is why Tenya voted for him (even though he wanted to be Class President). After Ochako asks if he's from an upper-class family, Tenya confirms that he is, telling Ochako 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 Ochako 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 tells 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 villains, much to Tenya's surprise. Tenya evacuates 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 Ochako in the process. No. 13 asks Tenya to dash back to Yuuei as fast as he can and inform the school of their situation. Although Tenya is reluctant to do so as it would be disgraceful to abandon his classmates, but after being encouraged by Rikidou, Ochako and No. 13, Tenya decides to run back to Yuuei. Before he can reach the exit, he is intercepted by Kurogiri, but Mezou Shouji distracts the villain long enough for Tenya to reach the exit, but Kurogiri tries to stop him once again only for his attempt to be foiled by Ochako and Tenya escapes to Yuuei.

Tenya, on his way to Yuuei, runs into All Might and tells him about the situation. Tenya manages to get to Yuuei and gets the Hero 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.

Sports Festival Arc
After the fourth period of modern literature ends, Tenya is seen with Izuku and Ochako, listening to Ochako's backstory and reasoning for becoming a heroine, which Tenya finds to be admirable. 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 Ochako 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 Shouto, Momo and Denki. Shouto 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.

Shouto orders Momo to prepare an insulator sheet and tells Denki to prepare to release his electricity. Shouto 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, Shouto immobilizes the stunned teams by freezing their legs. Shouto takes one of the headbands of the teams while charging forward to fight Izuku's team. Fumikage's Dark Shadow tries to attack Shouto but Momo uses her Quirk to block the Dark Shadow. Shouto'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 Shouto 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 Shouto, Tenya tells Shouto to pull himself together which snaps Shouto 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, Ochako 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 Shouto's match with Hanta, becoming shocked and horrified when Shouto 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 Ochako 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 Ochako must be pleased. However, Ochako politely declines Izuku's offer, saying that she will be all right. Tenya, along with Izuku, go to their seats to watch Ochako'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 Ochako when she gets hit repeatedly by Katsuki's explosions. During the match between Izuku and Shouto, Tenya becomes shocked that Shouto is using his fire power despite him saying that he never would. After Shouto defeats Izuku, Tenya along with Ochako, 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, 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 Shouto. 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 Eijirou, Tenya tells Izuku he will be back and goes down to the ring.

Tenya faces his opponent, Shouto, in his third round match. After the match begins, Shouto attacks first with a wave of ice but Tenya dodges the ice by jumping towards Shouto. While in the air, Tenya notes that now Shouto 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 Shouto with a speed-enhanced kick, but Shouto dodges his kick. Tenya quickly counters and attacks Shouto with another speed-enhanced kick which slams Shouto down onto the floor and injures him. Shouto grabs Tenya's leg, but Tenya kicks Shouto away. Tenya grabs Shouto and proceeds to try and throw Shouto out of bounds before Recipro Burst ends. However, along the way, Tenya realizes that there is ice in his mufflers and he slows down. Shouto 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 Ochako, watches the match between Fumikage and Katsuki. After Fumikage surrenders, Tenya tells Izuku and Ochako to watch the final match closely for their revenge later to which Izuku and Ochako agree with. 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 and tells Tenya to stay calm. Tenya is shocked at the news his mother is telling him and becomes distraught.

Tenya tells Ochako 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; use Ingenium as his Hero name.

Field Training Arc
Two days after the Sports Festival, Tenya is running to Yuuei 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. Tenya is in class and during the Hero Informatics Period, Shouta shows the Pro Hero nominations which reveals that Tenya received 301 Pro Hero nominations to which Ochako congratulates him for. Afterwards, Class 1-A have to decide on Hero names. Tenya, along with Izuku, are the last ones yet to reveal their Hero names. Tenya struggles on whether to use his brother's Hero name, Ingenium or not. However, 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 Ochako (with Ochako nodding in agreement) as they are friends. Tenya says that he will. Tenya 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 Normal Hero. 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.

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 three 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 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 he has avenging eyes and warns Tenya not to meddle with him otherwise even children will become targets. Stain prepares to walk away. 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. 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. However, Stain is punched in the face by Izuku Midoriya which stops Stain from killing Tenya. Tenya is shocked to see Izuku.

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. Suddenly, a column of fire and ice attacks Stain, forcing Stain to stop his attack on Tenya and dodge the fire and ice. Shouto reveals himself as the one that attacked Stain. Tenya is shocked to see Shouto.

Shouto battles Stain. As their battle gets underway, Tenya begs Shouto to stop fighting as he inherited Ingenium's Hero name. Shouto criticizes Tenya for making a vengeful face, saying that the Ingenium he knows would not make such a face. Izuku and Shouto 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. Shouto replies that if Tenya wants to stop them he must stand up. As Stain breaks through his wall of ice, Shouto encourages Tenya to set his eyes on the man 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 Shouto. Tenya 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 Shouto. Stain's Quirk wears off and Tenya gets up with the motivation of not wanting to be outpaced as a Hero by Izuku, Shouto 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 Shouto 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. Shouto 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 Shouto to cool down his leg, but Stain attacks Shouto with daggers to which Tenya intercepts and falls down to the ground. Shouto cools Tenya's leg, restoring Tenya's mobility. Tenya uses Recipro Extend and leaps into the air towards Stain. Tenya 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 Shouto shoots a stream of fire into Stain's face. Tenya and Shouto's additional attacks finally cause Stain to lose consciousness, defeating him. Tenya and Izuku land safely onto the ground thanks to Shouto's ice ramp. Shouto decides to tie up Stain with Izuku suggesting that they remove Stain's weapons.

Izuku, Shouto, Tenya and the Pro Hero leave the alley with the unconscious restrained Stain in tow. Tenya offers to pull Stain but Shouto tells Tenya that his arm is 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; Shouto tells Tenya to pull himself together because he is the Class President with Tenya complying. Out of the blue, the winged Noumu-like creature grabs Izuku; suddenly, Stain wakes up and defeats the winged Noumu-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. After Stain loses consciousness for the last time, Tenya becomes shocked that Stain is still standing. Tenya, along with Izuku and Shouto are taken to the Hosu General Hospital to have their wound treated,

The next day at Hosu General Hospital, the recuperating Izuku states to Shouto and Tenya that it is a miracle that they are still alive as Stain could probably have killed him if he wanted to. Shouto praises Tenya for his bravery but Tenya admits that he doesn't deserve any praise. The Chief of Hosu Police, Tsurugamae Kenji arrives and tells Izuku, Shouto and Tenya that the Hero Killer is undergoing treatment. He states that Izuku, Shouto 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 Manuel due to their negligence) will be given punishment. Shouto becomes furious that Tsurugamae expected them to follow the rules and let people die as a result. Izuku, Gran Torino and Tenya stop Shouto. However, Tsurugamae states that there were limited witnesses and as a result there will not be any punishment for Izuku, Shouto 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 Manuel but Manuel criticizes Tenya for his actions, asking him to never do it again. Tenya along with Izuku and Shouto thank the Chief of Hosu Police for not punishing them. Tsurugamae states that Tenya along with Izuku and Shouto 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. Shouto apologizes causing Izuku to ask why; Shouto states that whenever he is involved, people's hands go bad. Tenya and Izuku are surprised that even Shouto can crack a joke but Shouto says he is serious, causing the three young Heroes to laugh together.

The workplace training comes to an end and Tenya returns to Yuuei. 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. During Foundational Hero Studies, 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.

After Foundational Hero Studies 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 Ochako and Izuku.

End of Term Test Arc
One week before the end of term test, Tenya along with Izuku encourage Denki and Mina to do their best. In the lunchroom, Izuku, Tenya, Shouto, Ochako, Tsuyu and Tooru eat at a table, discussing 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 Yuuei'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 uninhabited city 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.

Tenya and Mashirao manage to get past Powerloader and pass the practical test.

Back in class at Yuuei, 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 Shouta 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; Shouta admits that using logical ruses is a mistake and will reflect on it. Tenya along with his class go to Kiyashi Ward Shopping Mall to buy necessities for the forest lodge.

School Trip Arc
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 Yuuei, Shouta 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.

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. However, Class 1-A notes that Class 1-B isn’t at the rest stop. Suddenly, two females wearing cat-like costumes and a small boy appear; the females excitedly introduce themselves as the professional Hero Team, The Pussycats. The black haired female explains to Class 1-A that they will be staying at the base of a mountain which is a part of their domain; they have three hours to reach the base of the mountain using their Quirks as they please and those who don’t arrive there by 12:30 pm won’t be served lunch. Soon, Class 1-A realize that they have already arrived at their destination and their training camp has already begun with the Pussycats being their supervisors. Some of Class 1-A try to leave, but Pixiebob uses her Quirk to create a landslide of dirt that causes Class 1-A to fall into a forest called Forest of Magic Beasts, which they must traverse to reach their destination. Suddenly, Class 1-A are confronted by a beast; Kouji 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 Shouto, Katsuki and Izuku mobilize and use their Quirks to destroy the dirt beast.

After Izuku, Tenya, Shouto and Katsuki destroy the dirt beast, Class 1-A begins traversing the Forest of Magic Beasts. However, the journey through the forest to the Cabin takes around about 8 hours. Class 1-A arrive at the facility, battered and tired. It is now 5:20 pm in the evening. Pixiebob 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. Pixiebob then commends Izuku, Tenya, Shouto and Katsuki for taking quick action against one of her Earth Beasts and concludes that they have experienced action against villains. After Kouta punches Izuku in his crotch, Tenya goes to check on Izuku and admonishes Kouta for his actions. However, Kouta harshly replies that he doesn’t want to be with people who want to become corny Heroes; Tenya is taken aback by Kouta'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 go 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 Kouta.

The next day at 5:30 AM, Class 1-A are outside the training camp cabin. Shouta greets his students and tells them that they will undergo reinforcement training to strengthen and upgrade their Quirks which will also allow Class 1-A to obtain their temporary licenses.

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 Tooru, Kyouka and Momo's conditions. After Eijirou and Shouta explain about a transmitter being planted on a villain by Momo and Yousetsu, Tenya deduces that Eijirou 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 Eijirou 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 he fully aware that the matter should be dealt by professionals, Eijirou 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.

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

Later that night, Tenya appears before Izuku, Shouto, Eijirou 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. Tenya is angry and frustrated that they are not taking his concerns, feelings and worry into consideration; Tenya says that he doesn’t want to see Izuku or any of them land up with severe injuries. Shouto tells Tenya that they will not engage the villains in combat while Eijirou 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, Shouto, Momo and Eijirou board a train to travel to a place called Kamino Ward, a place in Yokohama City in the Kanagawa Prefecture. At Kamino Ward, Izuku along with Shouto, Eijirou, Momo and Tenya put on disguises to make infiltration easier as well as to prevent the League of Villains from recognizing them. The disguised group exit the clothing shop and observe a video clip of Yuuei's public apology.
