Final Exams Arc
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. Yuga is paired with Ochaco Uraraka and they must face Thirteen in their test exercise.

Yuga, Ochaco and Thirteen arrive in an uninhabited city where Class 1-A's test exercise will take place. In the city, Thirteen explains the 30-minute test; Ochaco and Yuga 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.

Ochaco and Yuga reach the escape gate but before they can go through it, Thirteen creates a Black Hole, causing the duo to hold onto a guardrail to prevent themselves from being sucked in. Yuga fires his Navel Laser from his knees (thanks to his Hero Costume) at Thirteen but the attempt fails as Thirteen easily sucks away the lasers. Ochaco tries to think of a plan, causing Yuga to surmise that Ochaco is thinking about what Izuku would do; Yuga then asks Ochaco if she likes Izuku, which shocks Ochaco and makes her blush, causing her to let go of the guardrail out of embarrassment. As a result, Ochaco gets drawn towards Thirteen, much to their shared surprise. Facing Thirteen directly, Ochaco instinctively uses her combat skills learned from Gunhead and manages to handcuff Thirteen, allowing her and Yuga to pass the practical test.

Back in class at U.A., Yuga learns that he passed the written test and will go with his classmates to the forest lodge which is a boot camp. Yuga along with his class go to Kiyashi Ward Shopping Mall to buy necessities for the forest lodge.

The first semester has come to a close and summer break has begun.

Following the end of the semester, Yuga is invited by Deku to participate in an endurance training session, along the rest of Class 1-A boys. When Katsuki arrives and challenges Izuku, the boys opt to compete against each other by sprinting down the pool. When is Yuga turn, he tries to reach the other end of the pool using his Navel Laser without touching the water at all. However, in the middle of the flight, he begins to feel a intense pain in his stomach, causing him to deviate and collide with Hanta, who also is trying to reach the other side using his Quirk without getting in the pool. Both students fail into the swimming pool. Shoto wins the race.

After this, all Class 1-A prepare to watch the final race between Midoriya, Bakugo and Todoroki, but before they can start, Aizawa arrives and cuts their Quirks off due to their time limit for the pool expiring, kicking all the students out of the pool area.

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

To reach their destination, they must traverse the forest, which is inhabited by dozens of hostile earth monsters created by Pixie-Bob. The Students work together to fight their way through the forest. Yuga uses his quirk to destroy the clay creatures. The journey through the forest to the Cabin takes them around eight hours before finally arrive at the facility, battered and tired.

On the night of the third day of training, Yuga is paired up with Momo for a test of courage presented by the Pussycats. Minoru tries to trade partners with Yuga but he refuses. Class 1-A students traverse the forest while Class 1-B students try and scare them in the dark. Their fun event is interrupted by the arrival of the League of Villains' Vanguard Action Squad. The forest is filled with poison gas that leaves most students unconscious.

Momo creates gas masks and rushes through the forest, handing them out to all the students. She joins up with Yosetsu so he can guide her to the students in Class 1-B. Momo ask Yuga to watch over the unconscious Kyoka and Toru and take them back to the facility. Near the Vanguard Action Squad's rendezvous point, Yuga hides behind a bush along with Kyoka and Toru. Yuga contemplates on what to do because he follows Momo’s instructions, but Dabi and Twice’s presence are preventing him from doing that. Dabi seems to spots the bush Yuga is hiding behind, much to Yuga’s fear. Dabi prepares to go and check, however, he stops after Twice informs him that they must also call back Nomu since he only responds to Dabi. Yuga is relieved that Dabi did not discover him.

Izuku, Mezo and Shoto land along with Mr. Compress at the Vanguard Action Squad's rendezvous point; they engage in battles against Himiko and Twice until Kurogiri arrives to retrieve the Vanguard Action Squad. Mr. Compress reveals that he hid the real marbles containing Fumikage and Katsuki in his mouth. Mr. Compress slowly enters Kurogiri's Warp Gate. Suddenly, Yuga fires his Navel Laser at Mr. Compress's face, breaking his mask and causing Mr. Compress to spit out Katsuki and Fumikage.

Thanks to Yuga's actions, Mezo manages to rescue Fumikage, but Dabi grabs Katsuki's marble before Shoto can reach it. Dabi, Mr. Compress and the captured Katsuki teleport away from the training camp.

After Eijiro and Shoto state their intentions to save Katsuki themselves, Yuga is also against the idea of attempting to rescue Katsuki along with the majority of the class; Yuga suggests that they leave Katsuki’s rescue to the Pro Heroes since they have been prevented from partaking in combat, to which Fumikage agrees with Yuga.

Yuga watches and fears the All Might vs. All For One fight on T.V. along with his relative.

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 the students because he knows that five f them 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 further more says he would have expelled everyone but Bakugo, Hagakure and Jiro from the school, if it weren't for All Might's sudden retirement.

Class 1-A arrange their luggage in their respective bedrooms. Later that night, the boys of Class 1-A are in the common space on the first floor. The girls of Class 1-A show up and Mina Ashido suggests a room showcasing competition. When they check out Yuga’s room, it has an entire set of mirrors of different sizes, as well a large portrait of himself, a disco ball and an armour. They say it is very bright with multiple lights, but Aoyama calls it "dazzling". Mina and Hagakure completely saw it coming. Later, when they check Kyoka's room, Yuga and Denki comment on how it wasn't ladylike, leading to Kyoka to attack both of them.

The following day, Shota tells to Class 1-A that their next goal is to obtain their "Provisional Hero Licenses" Shota announces that theywill be working on developing their own special moves, much to the class' excitement. The class visits the Gym Gamma, where Cementoss creates a training ground for the class with Ectoplasm using his quirk to create villains for the class to practice their moves on.

Yuga trains his Quirk until the day of the Provisional Hero License Exam. Outside of the National Dagobah Arena, Class 1-A meets with students from Shiketsu High School and Ketsubutsu Academy High School. Before the exam starts, Yokumiru Mera from the Hero Public Safety Commission explains that the first part of the exam involves thinning out the amount of people who can succeed by playing a game, where people put three targets on their body and are given six balls to throw at the other examinee's marks. Those whose targets have been hit are disqualified. Participants need to eliminate two students to move on to the next phase of the exam.

As the exam starts, the students of the other schools focus entirely on U.A. However, Class 1-A is able to defend themselves and 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. Due to this attack, Yuga gets scattered, and have to defend himself from the attacks of the rest of the participants.

The situation becomes complicated for Yuga, since two of his Targets were hit and only had one before being eliminated, so he decides to hide among the rocks. Tenya, who was looking for her classmates, found Yuga found Yuga and decided to work with him so that they could find their classmates and pass. However, Yuga was content with the rest of Class 1-A passing ahead of him. Tenya refused to leave Yuga behind as he is the president of Class 1-A and as such it is his duty to support everyone including him.

However, they find themselves in the heat of battle against dozens of examinees from different schools ready to take them out. As Yuga thinks that the situation is bad, Tenya saves him 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.

Seeing that he is holding Tenya back, Yuga fires his Navel Laser  upwards; Tenya wonders what Yuga is planning. Yuga tells Tenya that he has already lost two targets and does not want Tenya to go down with him and thus decided to use himself as a decoy to attract more examinees which will allow Tenya to outspeed and attach his balls to two of them while they are distracted. Yuga admits that his dream is to be equal with everyone else.

Enemy students arrive, but just before they attack Tenya, all the remaining 1-A students make their way towards them, and manage to defeat the other students. On the ground, Yuga is confused as to what is going on; Mina Ashido tells Yuga it is thanks to his Navel Laser that they managed to group up with him and Tenya. The remaining Class 1-A students work together and they begin passing one after the other. Tenya criticizes Yuga that he is the only one that doesn't see himself on the same level as the others, as he's the beacon that allowed Class 1-A to succeed. Yuga and Tenya eliminate their last targets to fill the final two spots for the first phase. With that, Yokumiru announces the end of the first phase.

A while later, Aoyama leaves but used some cheese to say he knows Izuku's secret which he left behind for Izuku as the latter (who was aware of this) gets up and sees the message. The next day, Yuga does his training as he calls out to Izuku and shows him a new move he created, though it causes him severe stomach problems. Seeing his state, Izuku asks the instructor for permission to take Yuga away from training to recuperate before he asks him what he meant in his message. Yuga explained that he is aware of Izuku not being accustomed to his quirk and reveals that he went through a similar experience. Yuga goes on detailing his childhood of having to wear a belt to prevent his powers from leaking out and how he noticed it was similar to Izuku's initial lack of control of his before they both overcame it. He then tells Izuku he is not alone in hardships as its better to face them together or they won't excel. His words cause Izuku to smile and thank him for his support before Yuga suffers from another stomach problem. After a few days, he and Izuku become good friends with some of the class noting Yuga's more livelier attitude and his association with Izuku.
