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 Yuuei. In Class 1-A, Mashirao notes that if the Hero Killer would have been present with the Villain Alliance at the USJ, they wouldn't have made it out unscathed. During Foundational Hero Studies, Mashirao along with Izuku, Tenya, Mina and Hanta are the first group to partake in the rescue training race. Mashirao completes the race.

Mashirao is paired with Tenya and must face Powerloader in their test exercise.

Tenya, Mashirao and Powerloader arrive in an uninhabited city where their test exercise will take place.

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.
