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 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; 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; Koji 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; she praises Class 1-A for figuring out her Earth Beasts quickly and easily. Class 1-A fetch their luggage from the bus and put it in their rooms. Class 1-A 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 also allow Class 1-A to obtain their temporary licenses.

During the night of the third day, the Vanguard Action Squad attacks the training camp, filling the forest with poisonous gas and fire. Momo runs into Yuga and asks him to take the unconscious Kyoka and Toru 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 was instructed by Momo to take the unconscious Kyoka and Toru back to the facility, but Dabi and Twice’s presence are preventing him from doing that. Suddenly, Dabi 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 and Shoto nearly rescues Katsuki only for him to be snatched away by Dabi. Dabi, Mr. Compress and the captured Katsuki teleport away from the training camp.

After the capture of Katsuki, the training camp ends and Yuga returns home. Two days afterwards, Yuga visits Izuku in hospital. 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 explained that he is aware of Izuku not being accustomed to his quirk and reveals that he went through a similar experience.
