The final event is a tournament event, but Mashirao requests withdrawal from the event, saying that his participation in the Human Cavalry Battle was done by being manipulated and insinuates that it was because of Hitoshi's Quirk. Mashirao says that he understands that the tournament event is a rare opportunity and that walking away would be foolish, but while everyone was giving their best on their own he wasn't doing his best due to being manipulated.

Field Training Arc
Two days after the Sports Festival, Mashirao is in class. During the Hero Informatics period, Class 1-A has to decide on Hero names. Mashirao writes down and reveals his Hero name: Fighter Hero Tailman (武闘ヒーロー テイルマン).

After Class 1-A is finished formulating their Hero names, Mashirao is given a list of 40 work places in order to choose a work place 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 work place training, Mashirao is at the train station with his class so that he can travel to the work place 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 would have not 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. All Might commends the group for improving their Quirks broadly since entering Yuuei and asks them to prepare for the end-of-term test.
