After Class 1-A is finished formulating their Hero names, Mashirao is given a list of 40 workplaces in order to choose a workplace that he wants to train at. Mashirao talks to her, noting that she should have more nominations because she put on a good show in the Sports Festival. On the day of the workplace training, Mashirao is at the train station with his class so that he can travel to the workplace of his choice by train.

Workplace training comes to an end and Mashirao returns to U.A.. In Class 1-A, Mashirao notes that if the Hero Killer would have been present with the Villain Alliance at the USJ, they would not have made it out unscathed. During Foundational Hero Studies, Mashirao, Izuku, Tenya, Mina, and Hanta are the first group to partake in the rescue training race. Mashirao completes the race.

On the day of the exercise test, Mr. Principal reveals that Class 1-A will be fighting against U.A.'s teachers for their exercise test. Mashirao is paired with Tenya and must face Power Loader in their test exercise.

Tenya, Mashirao, and Power Loader arrive in an uninhabited city where their test exercise will take place. Power Loader 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 Power Loader and pass the practical test.

Back in class at U.A., Mashirao learns that he passed the written test and will go to the forest lodge with his classmates which is a boot camp. Mashirao is happy that everyone will be able to go to the forest lodge. The next day, Mashirao along with his classmates go to Kiyashi Ward Shopping Mall.

The next day after the shopping trip, at U.A., 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 is not 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. Mandalay 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 do not arrive there by 12:30 pm will not 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 Pixie-bob 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 8 hours. Class 1-A arrive at the facility, battered and tired. It is now 5:20 pm in the evening. Pixie-bob 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.
