Ochaco's parents own a construction business that hasn't gotten business in years. Neither of their quirks are compatible with the jobs, but Ochaco's is. Even as a small child, Ochaco desired to help her family out in any way she could. She wanted to work for them and use her quirk to help them make money. That way they could reduce labor costs and sell their heavy lifting equipment.
However, Ochaco's father told her that the way to truly make them happy would be for her to achieve her own dreams. As a result, Ochaco aspires to become a Pro-Hero in order to make enough money to give her parents an easy life.
Ochaco attends the U.A. Highschool Entrance Exams. She notices Izuku Midoriya tripping and uses her Quirk to float his body, preventing him from falling over. She apologizes for using her Quirk on Izuku without permission. She nervously admits to him her concerns about the test and departs by wishing him good luck.
During the practical portion of the exam, Ochaco scores twenty-eight points by using her Quirk on the villain-bots. Suddenly, a gigantic villain bot appears and tears apart the testing arena. Ochaco gets caught under debris as the robot approaches, putting her in danger of being crushed. Izuku puts his safety aside and rushes to her aid. It what was a complete shock to Ochaco, he defeats the massive robot with one powerful blow. However, Izuku breaks both his legs and his right arm in the process and begins to free fall. Ochaco frees herself from the debris in time to safe Izuku from falling from the great height. She smacks him just in time and uses her powers to float him as he's about to crash. The exams end shortly after. 
Ochaco returns to U.A. after the exams and asks Present Mic if she can transfer some of the points she'd earned onto Izuku. She tells Present Mic that Izuku had a zero score and that she needed to repay him for saving her. Present Mic thanks Ochaco for stopping by, but Izuku earned enough rescue points to pass. Ochaco also earned forty-five rescue points. Combined with her villain points, this places Ochaco third in the exam.
Ochaco is the last person to arrive in Class 1-A on the first day of school. She happens upon Izuku and Tenya talking at the door. Izuku is clearly embarrassed, but this doesn't stop Ochaco from telling him how awesome his punch from the exam was. A man clad in a sleeping bag, lying on the ground appears behind the trio. They are frightened when he tells them that they're taking up too much time chatting.
This man introduces himself as Shota Aizawa: their homeroom teacher. He immediately tells the class to dress in their P.E. attire and go to the training grounds. Ochaco is concerned that they will miss orientation, but Shota claims there isn't any time for formalities. Class 1-A follows Shota outside, where he announces that they will undergo quirk apprehension tests to determine their standing in the class. The person who places last will be immediately expelled. Ochaco expresses that she feels this is unfair to the students. Shota replies that many of the world's disasters are unfair and that the students will need to "Go Beyond" that.
In the fifty meter-dash, Ochaco uses her Quirk: "Zero Gravity" to negate the gravitational pull on her clothes and shoes. The added speed allows her to finish in 7.15 seconds, which is faster than her previous score from junior high. On the pitch test, Ochaco achieves an infinite score by floating the ball into the atmosphere. Izuku goes next, but Shota erases his Quirk to stop him from breaking his arm. Izuku recognizes him as the Pro-Hero Eraserhead, but Ochaco and other students do not recognize that name. Then Izuku throws the ball over seven hundred meters by breaking his finger and Ochaco cheers him on.
Following the physical tests, Shota reveals the student's scores. Ochaco places tenth out of the class while Izuku comes in last. Just when Izuku believes he's been expelled, Shota reveals that no one is going home and that threat was just a logical deception. Ochaco and most of the students are shocked by this revelation.
Afterward, Ochaco catches up with Izuku and Tenya to ask them if they want to walk to the station together. She recognizes Tenya by his name but accidentally calls Izuku by Deku. Izuku explains that Deku is a nickname that Katsuki uses to bully him. Ochaco likes the name Deku. She says it would make a great hero name and that it's cute. Ochaco and her new friends Tenya and Deku walk home together.
Ochaco eats lunch with Izuku and Tenya the next day. That afternoon, they attend Hero Basic Training class taught by All Might. All Might announces their first lesson will be combat training. Ochaco and her peers dress in their new costumes and meet their teacher at training ground beta. She tells Izuku she likes how simple his costume is, but dislikes how her own costume is too tight on her. All Might begins to explain the Battle Trial the students will undertake but gets interrupted when Ochaco and others keep asking questions. The students are paired up into teams of two and will fight mach-battles inside buildings. One team will be designated as the heroes while the other will be the villains. The objective of the heroes is to capture the villains or recover the payload the villains protect.
Class 1-A draws lots to choose their partner and Ochaco ends up with Izuku as her partner. All Might chooses their opponent at random as well. Ochaco and Izuku are chosen to be the hero team up against Katsuki and Tenya. They wait outside the building for five minutes after their opponents enter.
Ochaco tells Izuku that she's excited to be able to see All Might up close. Her enthusiasm is interrupted when she realizes Izuku is so nervous that he's sweating through his costume. Izuku admits that he's afraid to face Katsuki because of how powerful he is. He goes on to say that he must do better and that he won't lose in the Battle Trial. Ochaco says it's a fated battle between rivals and that they will win as a team.
They enter the building and Ochaco follows Izuku around the narrow corridors until Katsuki surprise attacks them. Izuku grabs Ochaco in time for both of them to evade Katsuki's explosion. Katsuki attacks again, but Izuku catches his arm and uses a shoulder toss to counter and slam Katsuki onto the ground. Ochaco cheers as she watches Izuku tell Katsuki that "Deku" is the name of a hero.
Katsuki recovers and kicks Izuku. Izuku tells Ochaco to go ahead without him while he fights Katsuki. Ochaco reaches Tenya and the fake bomb on the floors above. She walks in on Tenya getting himself into the villainous mindset. Ochaco finds this funny and lets her guard down by laughing out loud. Tenya notices her and reveals that he's removed anything for Ochaco to float from the room. As he monologues over his plan, Ochaco contacts Izuku and tells him she found the payload in the middle of the fifth floor.
Katsuki uses a giant explosion to attack Izuku that shakes the entire building. In the chaos, Ochaco floats herself and makes a jump for the weapon. However, Tenya is too fast for her and uses his Quirk to keep it out of her reach.
Izuku and Ochaco come up with a plan where the former uses his Quirk to break up the higher floors of the building. This gives Ochaco the opening and the tools to use her Quirk effectively. She swings a large pillar to send stones flying at Tenya, nicknaming the technique Home Run Comet. While Tenya avoids the attack, Ochaco jumps onto the payload and wins the Battle Trial.
Following their battle trial, Ochaco, Tenya, and Katsuki are critiqued in the monitoring room. All Might declares Tenya the MVP of the trial and asks the class why he chose Tenya. Momo answers his question. She says Ochaco dropped her guard mid-battle and she took advantage of the trial by using an imprecise special move. Izuku returns to class later on. Ochaco walks in with Denki soon after and immediately runs over to Izuku. She is concerned about his wounds but he tells her that he's fine. He asks where Katsuki went. She tells him Katsuki left and Izuku goes after him.
Ochaco gets questioned by reporters on her way to school the next day. They ask what All Might is like in person. Ochaco can't quite describe him, but she does call him very muscular. Class 1-A votes for their Class President during homeroom. Tenya suggests the class vote for it. Ochaco quietly uses her vote on Izuku so Katsuki doesn't notice. Izuku and Momo are voted in as class representatives.
At lunch, Ochaco eats and talks to Izuku and Tenya about the class president. Tenya tells Izuku he voted for him as well. Ochaco mentions that Tenya looked the part of being class president. Tenya accidentally mentions his families hero agency, prompting Ochaco to ask if his family is wealthy. Tenya admits that he comes from a family of pro-heroes and that the hero Ingenium is his elder brother.
Suddenly the school's alarms go off and the students begin to evacuate in a panic. Ochaco and the others get caught in the mob created by the panic. She calls for Tenya's help and he reaches his hand out to her. He requests that she help him float above everyone else. Using his Quirk, Tenya moves over the corridor and dispels the panic by informing everyone it's just the media trespassing on campus grounds.
Later on, Shota announces to the Class that they will partake in rescue training at an outside facility. Ochaco gets dressed in her costume save for her helmet. She notices Izuku wearing his P.E. uniform rather than his costume. He explains it got wrecked during combat training. Class 1-A boards the bus and Katsuki eventually starts fighting with his peers. Momo complains that their conversation is too vulgar, but Ochaco says that it is fun to hear them argue. Class 1-A reaches the Unforeseen Simulation Joint and are met by the Space Hero: Thirteen. Thirteen speaks to them about the importance of using their Quirks to help others. The teacher's speech is interrupted when villains suddenly enter the facility through a warp gate.
Shota fends off the villains on his own and leaves Thirteen to evacuate with the class. They prepare to escape, but they are cut off by the villain Kurogiri. He explains he and his allies are the League of Villains. They came to the U.S.J to kill All Might, but he isn't there. Katsuki and Eijiro attack the mist villain. Kurogiri is able to avoid their attack and counterattacks by warping the class across the facility. Tenya grabs Ochaco and Rikido and evades the warp gate.
Only Ochaco, Tenya, Rikido, Mezo, Mina, and Hanta remain on the entrance platform with Thirteen. Thirteen instructs Tenya to run back to the main campus to get help. He's reluctant at first, but Ochaco and the others encourage him to save the day. Kurogiri overhears their plan and attacks. Thirteen counters with their Black Hole Quirk to vacuum in Kurogiri's mist. Kurogiri turns Black Hole's power against Thirteen by opening a gate behind them. Thirteen is nearly torn in half and is ultimately defeated by the villain.
Ochaco and Mina to rush to Thirteen's side as Tenya makes a break for the door. As Kurogiri chases Tenya, Ochaco notices his neck armor and grabs it. She uses her Quirk to float Kurogiri's real body. He tries to recover, but Hanta and Rikido use their Quirks to throw him farther away. Thanks to all of their help, Tenya makes it out of the U.S.J. to run back to the school.
All Might appears at the U.S.J and rescues Shota from the villains. Ochaco finds Tsuyu and Minoru carrying Shota back and offers to help them. She cheers All Might on during his fight with the villain Nomu. Ochaco is overjoyed when Tenya eventually returns to the fight with reinforcements to save everyone from the League of Villains. In the aftermath of the attack, Class 1-A are debriefed by Detective Tsukauchi. Ochaco and Tenya ask abou Izuku's wellbeing. The police officer confirms Izuku will be fine. Ochaco and all her other peers return to U.A. High uninjured.
Two days after the attack on the U.S.J., Ochaco and her classmates return to school discuss the attack. Shota returns to class and the students get lectured about the importance of the upcoming U.A. Sports Festival. At lunchtime, Ochaco puts her game face on and emphatically and repeatedly expresses to everyone that she's going to do her best in the festival. Shortly after, Izuku and Tenya ask Ochaco why she wants to become a hero.
Embarrassed, Ochaco explains that she wants to become a hero to make money. This surprises Izuku and Ochaco apologizes for appearing to be greedy. Tenya says that it's perfectly fine to strive to support her own wellbeing. Ochaco explains that her families business hasn't been getting work and that they're poor. Izuku and Tenya state that Ochaco could float the equipment, to which she agrees. She expressed this idea to her father years ago, but he told her that she should achieve her own dreams to make them happy. Now Ochaco strives to become a pro-hero to make enough money to give her parents an easy life.
All Might suddenly appears and takes Izuku out for lunch. Ochaco finds this adorable and excuses Izuku. She joins Tenya for lunch and asks what All Might could want with Izuku. Tenya points out that Izuku helped All Might at the U.S.J and that they both have similar Quirks.
Later on after class, Class 1-A's doorway is blocked by a mob of students. Katsuki points out that they're rival students scouting out the competition and demands that the "extras" move out of the way. A student from the general studies course confronts Katsuki and declares war on Class 1-A. This shocks Ochaco and her peers, who don't know who this student is. Then a student from Class 1-B appears and yells at Katsuki. Ochaco and the others fear everyone hates their class thanks to Katsuki.
Ochaco trains for the next two weeks prior to the festival. On the day of the U.A. Sports Festival, Ochaco gets ready with her classmates in the waiting room. Shoto confronts Izuku and quietly earns Ochaco and everyone else's attention. He declares that he will defeat Izuku, to which Izuku responds that he will aim for the top. Class 1-A is called out onto the festival arena, where Katsuki gives the pledge. Ochaco and the others aren't surprised when all he says is that he will win.
The first round of the festival is an Obstacle Course four kilometers around the outside of the stadium. Ochaco makes it through the doorway despite Shoto's ice attack but is stopped by the "Robo Inferno" blockade of villain bots. Ochaco uses her Skill Release technique to destroy the robots her in path. She eventually makes it to the second leg of the race: "The Fall".
Ochaco and Mina watch Tsuyu effortless traverse the pitfall laced with pillars connected by tightropes. Ochaco questions when the school had time to build this obstacle. Then a student from the support course appears and loudly introducers her gadgets. Ochaco and Mina ask her why she can use those tools. The girl explains students from support can use any tools they develop themselves. She uses her gadgets to cross The Fall, all while wildly announcing it all. Ochaco watches in awe before pumping herself up to continue on.
Ochaco finishes the race in sixteenth place, qualifying her for the second event: the Cavalry Battle. She congratulates Izuku on getting first place. Midnight explains the Cavalry Battle rules. Ochaco points out that each team will have a different point value based on its member's placement in the first event. Midnight yells at Ochaco and Mina to be quiet and allow her to finish explaining.
The Cavalry Battle lasts fifteen minutes, and each team must try to steal opponent headbands that represent point value. Ochaco chooses to team up with Izuku because it's better to team up with friends. They try to recruit Tenya but he refuses because he wants to defeat Izuku and joins Shoto. Mei Hatsume asks to join Izuku so her gadgets can be in the spotlight. Ochaco recognizes her as the girl from the obstacle course, but Mei ignores Ochaco completely.Ochaco takes notice of how well Izuku and Mei start to get along. Izuku recruits Fumikage as the last member of Team Midoriya.
At the start of the event, Team Tetsutetsu traps Team Midoriya using one of their quirks. Ochaco finds herself unable to get free, but Izuku uses Mei's jetpack to get away. Ochaco uses her quirk to float everyone while wearing Mei's hover soles. She steps in one of Minoru's balls and gets her foot stuck to the ground. Team Mineta charges at Team Midoriya and attacks using Minoru and Tsuyu's quirks.
Izuku uses the jetpack to forcibly free Ochaco and takes to the skies once more. This time, they are met by Katsuki who tries to blast them out of the air. Fumikage's Dark Shadow protects the team and Ochaco makes a safe landing. She points out she can no longer fully control their flight path with one of the soles busted. Izuku chooses not to risk it and to rely on their increased mobility from Zero Gravity. Before they get any rest, Team Midoriya is confronted by Team Todoroki.
Team Todoroki and several others attack Ochaco's party all at once. Denki electrocutes the other teams while Dark Shadow protects Team Midoriya. Even with increased mobility, Team Midoriya can't outrun Tenya's team. Izuku skillfully outmaneuvers Team Todoroki for most of the remaining time. With only a minute remaining, Tenya uses a special move to steal Izuku's headband in a blink of an eye. Izuku pleads with his team to counterattack because they don't have another chance. Although Fumikage is hesitant, Ochaco encourages the team and rushes them towards their opponents. Ochaco's support prompts Izuku to use his quirk and attack Shoto head-on.
Izuku manages to grab one of Shoto's headbands. Mei notices that he grabbed the wrong one in the fray. Team Midoriya makes one final push but time runs out. Fumikage reveals to his team that he was able to grab one of Shoto's headbands in the chaos. This gives them enough points to place in fourth, qualifying them all for the final event. Afterward, Ochaco talks to Tenya about keeping his special move a secret. She notices Izuku is missing and asks where he went.
After their lunch break, Denki and Minoru trick the girls of Class 1-A into dressing up as cheerleaders. Momo is devastated to find out they were fooled so Ochaco tries to console her. Midnight draws lots to pick the matchups for the final event: a one on one fighting tournament. Ochaco is matched up against Katsuki, who she's surprised to find that he has no idea who she is. The students are given an intermission before the finals, which Ochaco uses to cheer and calm her nerves.
She watches as Izuku fights Hitoshi Shinso in the first fight. Izuku nearly walks out of the ring while under the spell of Hitoshi's quirk. Ochaco and Tenya are worried during the battle, but Izuku eventually comes out on top. All three of them are terrified when Shoto freezes Hanta in a giant wall of ice. After Ibara Shiozaki defeats Denki, Ochaco notices Izuku muttering about counter strategies. He apologizes for thinking out loud and explains this is a hobby of his. He even shows Ochaco his data on her. Ochaco says that Izuku is amazing because of his drive and focus. Ochaco leaves to the waiting room after Tenya's advertisement laced duel with Mei.
Tenya happens upon Ochaco in the waiting room and is scared by her nervous expression. She admits that she is afraid to fight Katsuki. Izuku walks in shortly after and offers a strategy for Ochaco to prevail. Ochaco thanks Izuku for the trouble, but politely declines his offer. She says she may have relied on him too much in the Cavalry Battle and was embarrassed when Tenya chose to be independent of them. Ochaco plans to tackle this challenge on her own and tells Izuku that she'll see him in the finals. Following Eijiro and Tetsutetsu's match, Ochaco and Katsuki enter the fighting stage for the eighth and final fight of the first round.
Katsuki warns Ochaco to withdraw from the match because he's not holding back. She refuses and rushes Katsuki as their battle begins. She knows Katsuki starts the fight with a right hook but is unable to evade his Explosion quirk. She throws her jacket through the smoke as a feint and attacks Katsuki from behind. She nearly touches him, but Katsuki reacts quickly and blasts her away. Ochaco rushes Katsuki repeatedly, forcing him to counter-attack by blasting her with the full force of his explosions. Even after being exploded over and over, Ochaco remains steadfast in standing up to Katsuki.
Ochaco thanks Katsuki for keeping his focus on her. She had been using her quirk to float the debris created by the explosions. Ochaco collected a large amount of rubble that floats above the stadium. Once Katsuki realizes her plan, Ochaco releases the debris and sends a meteor shower falling down on Katsuki. She tries to take advantage of the opening created by her attack and rushes Katsuki.
To Ochaco's complete shock, Katsuki blasts all of the stones away in one massive blast. Katsuki comments that he knew Ochaco had a plan because he remembered that she's friends with Izuku. Ochaco is discouraged by her failure, but she still tries to fight on. However, she collapses shortly after. Her body has been pushed past its limit and despite her will to go on, Ochaco faints and Katsuki is declared the winner.
Recovery Girl heals Ochaco and she returns to the waiting room. Izuku enters the room, surprised to see her doing well. Ochaco pretends to be optimistic about the fight and Izuku almost notices. Her father calls, but she ignores it to encourage Izuku about his upcoming battle with Shoto. After Izuku leaves, Ochaco calls her father back. He congratulates her on a job well done. Ochaco says she didn't do very well and failed. He heartens his daughter by saying that she will make a great hero and that he's very proud of her.
Ochaco is moved to tears by her dad's words. She wipes her tears away and leaves marks around her eyes from rubbing them. She returns to the stands just as Izuku and Shoto face off. Tenya notices the marks and Fumikage says to use Izuku's battle as inspiration.
As their battle begins, Ochaco ponders how Izuku can avoid Shoto's ice. Izuku eventually inspires Shoto to unleash his flames. Ochaco is surprised to see the full might of Shoto's Quirk. After Izuku is defeat, Ochaco joins Tenya, Tsuyu and Minoru visit him in the nurse's office. They are distraught when they learn he needs surgery, but Recovery Girl escorts them out. Ochaco continues to worry about Izuku during the battle between Fumikage and Mina. Izuku returns to the stands after the second round. Ochaco expresses her concerns but Izuku says he wants to watch everyone's hard work pay off.
Ochaco cheers for Tenya during his battle against Shoto. She's disappointed when he's defeated. During Fumikage's bout with Katsuki, Ochaco points out that Fumikage can't attack because of the light created by Katsuki's explosions. She and Izuku welcome Tenya back to the stands after his loss. His phone starts to vibrate, making him shake. Ochaco and Izuku are frightened at first, but Tenya explains. Tenya leaves after answering the phone. He explains that Ingenium was hurt in a fight with a villain. Ochaco and Izuku watch the final fight between Shoto and Katsuki.
Afterward, Ochaco attends the closing ceremony along with all the other festival participants. Following the U.A. Sports Festival, Shota grants Class 1-A two days off from school to recover. The next day, Ochaco returns to her apartment from shopping. She ponders what she'll have for lunch and then notices her door is unlocked. Her parents surprise her with a party to celebrate her achievements in the festival. Ochaco expresses that she's very happy to see them.
Ochaco returns to Class 1-A once classes resume at U.A. High School. Shota announces that their current period will be spent on Hero Informatics. He explains that the students will need to choose their hero names. The pro hero draft nominations are revealed and Ochaco finds out she has twenty offers from pros. Ochaco is excited to see that both she and Tenya received nominations. Shota announces that all the students will intern with pros whether they received offers or not.
Midnight joins the class to help the students choose their hero names. Ochaco chooses and presents the name "Uravity", much to Midnight's liking. Izuku decides to choose the name Deku. He later gives credit to Ochaco for inspiring him to look at the name in a different light as Ochaco is visibly proud of Izuku's choice. Following choosing hero names, Shota tells the class they will have two days to choose among their nominations. Even those who received none will have a list to choose from because everyone will spend the next week interning with a pro-hero agency.
At lunchtime, Ochaco decides on her workplace of choice. She tries to ask Izuku about his choice, but he's too busy muttering. Ochaco, Mashirao, Mina and Tsuyu snap him out of it. Ochaco tells them that she's chosen the Battle Hero Gunhead's agency to intern at.
Izuku points out that Gunhead is a fighting hero and that he thought that Ochaco wanted to be a rescue hero like Thirteen. Ochaco replies that since her bout with Katsuki she has wanted to broaden her horizons. She explains that Gunhead sent her an offer and by interning with him she can get stronger and get a different perspective. Then she asks Izuku why he's trembling in his chair. He explains that it's exercise.
Ochaco asks Izuku to walk with her and points out that Tenya left without them. Izuku says Tenya likely already chose his internship. Then All Might suddenly appears and takes Izuku away. Later on, they meet back up and Izuku tells Ochaco he got an internship offer. She's excited and they walk home together. They're dismayed to find that Tenya has left school without them. Just prior to the start of internships, Class 1-A meets at the train station. Shota see's them off and they separate to go to their workplace of choice. Just before Tenya leaves, Izuku and Ochaco tell him he can talk to them if he needs a friend.
On the first day of internships, Ochaco goes on patrol with Gunhead. He explains that his agency specializes in controlling crime. They get requests for all types of jobs all at once filtered by city district. After the job is complete, the heroes must file a report in order to be paid for their service. After explaining, Gunhead says Uravity will catch on quickly. Ochaco notes that she didn't expect Gunhead to be so friendly.
The next day, Gunhead trains Ochaco and others on the basic fighting form. Ochaco notices that Gunhead strikes a cute pose while teaching her. Later, Ochaco receives an ominous message from Izuku containing only his location in Hosu City. She eventually finds out that Izuku, Shoto, and Tenya fought against the Hero Killer: Stain. She calls Izuku after the incident and finds out he's okay. Izuku confirms he's in good health, and Ochaco lets him rest so she can learn about what happened later. Gunhead catches Ochaco on her phone and teases her about talking to her boyfriend, to her embarrassment.
Towards the end of the internship, Gunhead trains Ochaco on fighting someone armed with a knife. She uses a fake knife to attack, and Gunhead easily takes her down while explaining it step by step. When she's defeated, Ochaco admits that Gunhead's martial arts are amazing. She realizes that despite his cuteness, Gunhead is a fierce combatant.
Ochaco returns to U.A. once the internship concludes. Tsuyu asks her how the internship went. Clad in a fierce aura, Ochaco replies that it was very enlightening. Her peers point out that she's found her fighting spirit and she's changed a lot in only a week.
Class 1-A takes part in a rescue race during All Might's basic hero training class. When the first group takes their starting positions, Ochaco puts her bet on Tenya to win. However, she's surprised and amazed to see that Izuku has a new mastery over his quirk, allowing him to traverse the race using a variety of athletic moves. Ochaco and her peers point out that Izuku's new moves are very similar to the way Katsuki propels himself through the air using his explosions.
Ochaco and the girls of the class change in the locker room after the races conclude before Minoru tries to peep on them but Kyoka stops them. After the school day ends, Ochaco walks home with Izuku and Tenya.
One week prior to final exams, Ochaco eats lunch with Tsuyu, Toru, Tenya, Shoto, and Izuku. They discuss what might be on their upcoming written and practical exams. Ochaco placed thirteenth in the midterms, making her nervous for their tests. Neito interrupts them to taunt Izuku, Shoto, and Tenya about their run-in with Stain. Itsuka knocks him out to stop him and tells the group she believes the practical exam will consist of fighting villain-bots.
After returning to class, Mina and Denki are overjoyed the learn about the practical. Katsuki berates them both for not being able to control their quirks. Then Katsuki calls out Izuku for stealing his moves. Ochaco points out that Katsuki is referencing how Izuku was flying around like Katsuki during the rescue race. Ochaco spends the few days leading up to the exam studying at her apartment. The day of the practical arrives following the three days of written tests and Class 1-A meets up with many of the teachers at the central plaza of the exam arena.
Shota and Principal Nezu reveal that the practical exam has been changed. Ochaco is surprised to learn that students will be fighting in pairs against the teachers. All of the matchups are revealed in order. Ochaco and Yuga are set to face Thirteen in the fifth practical battle. They will be allotted thirty minutes to either capture them or escape the battle stage through an escape gate. All teachers will wear compressed weights to give the students a handicap.
Ochaco waits inside the monitoring room for her battle to arrive. She meets Izuku inside. He explains his partner Katsuki doesn't want to speak. Ochaco replies that she's trying to gain inspiration from the other fights since Yuga is occupied looking at himself. Ochaco cheers for Eijiro and Rikido in their bout with Cementoss. Izuku states they will lose because their quirks have time limits while Cement does not. They are both shocked when Eijiro and Rikido are quickly routed and fail their exam.
Ochaco and Izuku cheer on Fumikage and Tsuyu in their fight with Ectoplasm. When they pass, Ochaco is happy to say that they are both smart heroes. They also watch Shoto and Momo's battle with Shota. Ochaco notices Shota does not chase them after Shoto uses his giant ice wall against him. Izuku points out that he may have overused his eyes. Ochaco and Yuga go next in a battle with Thirteen. Soon after it begins, Ochaco and Yuga are forced to cling to a guardrail for dear life as Thirteen uses their quirk to suck them in. Ochaco starts to wonder what Izuku would do in this situation and Yuga notices. He asks Ochaco if she has romantic feelings for Izuku.
Ochaco is extremely embarrassed and lets go of the rail. Thirteen stops their quirk from turning Ochaco into dust. Ochaco uses this opening and her training from Gunhead to efficiently take down Thirteen. When Thirteen tries to resist, Yuga pins them down and Ochaco puts on the handcuffs. Ochaco returns to the monitoring room after passing her own exam. She cheers for all of her peers, including Izuku and Katsuki's epic battle with All Might.
Class 1-A returns to homeroom after the finals. Shota announces that Ochaco passed both her written and practical exams. Even those who failed the exam will go on a school trip to a training camp in the woods over summer break. Class 1-A (save for Shoto and Katsuki) decides to go shopping together the next day at the Kiyashi Ward Shopping Mall in order to get supplies they will need for the trip. Most of them go their separate ways to find what they need, but Izuku and Ochaco remain together. Izuku tells Ochaco he needs new weights and asks what she needs. She replies a duffel bag and then remembers Yuga inquiring about their relationship. She gets embarrassed and runs off, leaving Izuku alone.
Ochaco eventually regrets leaving Izuku behind. She rationalizes her feelings for Izuku as platonic admiration and goes to find him. Ochaco finds Izuku entangled with League of Villains leader: Tomura Shigaraki. She threatens Tomura and he leaves. He warns Izuku not to follow him as he disappears into the crowd. Ochaco calls the police, but Tomura escapes.
The Police Force arrive due to Ochaco's call and temporarily close down the Kiyashi Ward Shopping Mall to investigate the whereabouts of Tomura.
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. 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; Izuku excitedly introduce the females 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. Izuku, Shoto, Tenya and Katsuki mobilize and use their Quirks to destroy the dirt beast.
After Izuku, Tenya, Shoto 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.
Class 1-A fetch their luggage from the bus and put it in their rooms. They go to the dining hall to have dinner. After finishing eating dinner, Class 1-A go to the hot springs.
The next day at 5:30 AM, Class 1-A are outside the training camp cabin. Shota greets his students and tells them that they will undergo reinforcement training to strengthen and upgrade their Quirks which will allow Class 1-A to obtain their temporary licenses.
During the night of the third day, Ochaco and Tsuyu are paired together for the test of courage. A few minutes later, the Vanguard Action Squad attacks; Himiko attacks Ochaco and Tsuyu in which Ochaco's arm was slightly wounded due to the ambush.
A few moments earlier before the Bakugo Escort Squad was formed, Tsuyu and Ochaco are fighting Himiko Toga who managed to slightly wound Ochaco's arm. Himiko notes that her Quirk requires her to make big wounds in order to suck her targets' blood. However, thanks to her machine, her Quirk's weakness is compensated by the machine's ability to drain blood from tiny wounds. Himiko begins to attack, to which Tsuyu responds to by flinging Ochaco away with her tongue. Tsuyu tells Ochaco to run back to the facility and call for help and says that she also plans on retreating with her. Suddenly, Himiko manages to wound Tsuyu's tongue with her knife. Tsuyu tries running away, only for Himiko to pin her hair to a tree with her machine.
Himiko prepares to drain Tsuyu's blood, however, Ochaco arrives to Tsuyu's aid, which causes Himiko to turn her attention to Ochaco. Himiko attacks with her knife, only for Ochaco to dodge. Ochaco then uses the martial arts skills she learned from Gunhead to force Himiko onto the ground. Straddling Himiko's back, Ochaco tells Tsuyu to restrain her arms. However, Himiko begins talking to Ochaco, calling her spectacular while noting that they are similar, as they are in love with someone. She tells Ochaco that she knows how she feels because they are girls; and begins talking about people who are in love strive to be like the ones they love, which enrages Ochaco. Himiko notes that love stories are fun and uses her machine to stab Ochaco's leg to drain her blood, who was unable to stop her due to being caught off guard with Himiko's talking.
Suddenly, the Bakugo Escort Team arrives and sees Ochaco. Himiko stops draining Ochaco’s blood and pushes Ochaco aside, not wanting to engage a large group of enemies and not wanting to die. Before retreating, Himiko sees Izuku and blushes. Himiko retreats with Ochaco wanting to follow her, butTsuyu stops her due to Himiko’s Quirk being largely unknown. After seeing that Ochaco and Tsuyu are alright, Izuku asks them to join the escort. However, Ochaco and Tsuyu wonder why Katsuki isn’t with them. Mezo, Shoto and Izuku turn around only to find that Fumikage and Katsuki are missing.
Suddenly, a masked villain appears on a tree branch and reveals that he used his “magic” to take Katsuki by turning him into a marble. The masked magician-like villain states that the Heroes don’t deserve someone of Katsuki’s caliber and notes that Katsuki will shine even brighter on the villains’ side. Izuku demands that he give Katsuki back.
Izuku hatches a plan to allow them to save Katsuki and asks Ochaco to make them weightless so that Tsuyu can throw them towards Mr. Compress. Ochaco and Shoto are unsure about letting Izuku help with the rescue, but after Izuku convinces them, Ochaco makes them weightless while Tsuyu flings them. Before Tsuyu flings them, Ochaco bandages Izuku's arms and wishes them good luck.
After the three young Heroes are sent flying towards Mr. Compress, Ochaco and Tsuyu run after them. They reach them but find out that they were too late to save Katsuki.
Two days later, Ochaco visits Izuku in a hospital near the training camp. Eijiro states a plan to rescue Katsuki, but most of Class 1-A are against the idea with Ochaco saying that Katsuki needing rescuing would disgrace and humiliate him.
Ochaco watches the broadcast of the battle between All Might and Sensei.
While waiting for the Second Exam to start, Ochaco overhears Hanta Sero tells Denki Kaminari and Minoru Mineta that Izuku saw Camie Utsushimi's naked body, which leaves her silent. After Camie walks away, Ochaco's heart starts pounding and she is not able to suppress her feelings and tries to speak with Izuku about something but the exam starts.
A rescue scenario is being broadcast to the examinees; large-scale destruction of buildings have resulted in large numbers of victims. The damage to the roads are severe and the emergency unit will be considerably late. Until the emergency unit arrives, all rescue activities will be left to the heroes and they must save every life they can. The waiting room door opens up and the one hundred examinees rush out to the disaster site to carry out their rescue operations. Ochaco, Izuku, Tenya, Minoru, and Mina Ashido head to the nearest affected urban zone.
Ochaco watches as Izuku tends to an injured child who gives him a hard time at first until Izuku's kind words reassure him. Izuku tells Ochaco and Tenya that he will take the child to the first-aid station but will return for them. As she watches him leave, Ochaco berates herself as she realizes she does have feelings for Izuku but realizes in order to focus on her dream, she must shut off her feelings for Izuku for the time being. The reason Ochaco found Izuku to be cool in the first place was because he does everything he can without giving up for the sole purpose of achieving his objective and found Izuku's determination admirable. Ochaco decides to do her best as and keeping focus on being a hero will aid her in doing so. With this drive, Ochaco springs into action.
Ochaco and Tsuyu intern under Ryukyu, thanks to Nejire, who recommended them after their field-training teachers rejected them.
One day, they defeat a villain together and use a new combo move called Meteor Fafrotskies. Ryukyu then tells them that the internship will help with their fighting skills and that they might help with "The Case", which is to team up with Sir Nighteye's hero office for an investigation.
Afterwards, she joins the rest of Class 1A when Momo makes Golden Tips Imperial tea for all of them and Ochaco shows a curious Izuku a video about tea. The two see the villain Gentle Criminal and wonder about his crimes.
