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. Izuku, Shouto, Tenya and Katsuki 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. 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. 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.

Mezou along with his class undergo training to improve their Quirks.

On the night of the third day of training, Mezou is paired with Fumikage for the test of courage. During the test of courage, the League of Villains Vanguard Action Squad begin their attack by filling the forest with poisonous gas. One of the villains part of the squad called Moon Fish ambushes Fumikage and Mezou. Mezou covers for Fumikage but loses one of his tentacles in the process. They manage to retreat from Moon Fish. However, the ambush causes Fumikage to lose control of his Quirk. Mezou saves Izuku from Dark Shadow's claw and explains the situation to him. They turn their attention to Fumikage; Fumikage has been restrained by Dark Shadow, who is now larger and more ferocious due to the power of darkness. The empowered and berserk Dark Shadow begins taking control of Fumikage’s body. Struggling, Fumikage pleads Izuku and Mezou to run away from him otherwise they will die. Izuku watches in shock.

The rampaging Dark Shadow attacks and destroys several trees around it. Dark Shadow attacks Mezou and Izuku, but Mezou is able to dodge in the nick of time. After maneuvering behind a tree, Mezou sees that Dark Shadow attacks anything that moves or makes, while also noting that Fumikage’s regret and indignation is intensifying Dark Shadow’s control over Fumikage as well as its own power. Fumikage pleads Mezou and Izuku to save the others and forget about him. Mezou informs Izuku that they need light to calm Dark Shadow down so that Fumikage can regain control; he tells Izuku that he can distract Dark Shadow while he runs back to the facility for help; Izuku is indecisive due to wanting to save Katsuki as well. Before Izuku can reply, Dark Shadow strikes at them, but Mezou is able to evade. Seeing that their situation is desperate, Mezou tells Izuku that he can either save Fumikage with him or save Katsuki by himself. Izuku apologizes to Mezou because he cannot make that decision and says that he has a plan. Mezou and Izuku arrive to where Katsuki and Shouto are along with Dark Shadow in pursuit, with Mezou asking one of them to make light. Before he can explain further, Moonfish senses Mezou and Izuku’s presence and sends one of his teeth to attack them. The rampaging Dark Shadow uses its enormous claw to crush Moonfish, destroying Moonfish’s teeth and knocking him out. Shouto and Katsuki are surprised at what happened. Izuku’s plan was to lure the rampaging Dark Shadow to their location by creating decoys from Mezou’s Replicant Arms which worked. Izuku is happy to see Katsuki, glad that he doesn’t have to save only one of his classmates and sacrifice the other.
