Provisional Hero License Exam Arc
On the day of the Provisional Hero License Exam, Emi excitedly walks up to Class 1-A and Shota, having apparently met him before. Shota recognizes her, though he is less than excited to see her. Emi then reveals to Class 1-A that she and Shota used to work together as partners, even claiming that the two of them had feelings for each other but Shota denies the latter claim. She then calls her class over to meet Class 1-A, revealing that she teaches second-year students at Ketsubutsu Academy High School.

While Emi's class appears excited to meet U.A. High School students, some of them, namely Yo Shindo, appear to have ulterior motives. Emi instructs her class to get ready for the exam and change into their costumes. As the students were getting changed, she asks Shota if he told his class about what happens to U.A. students every year at the Provisional Hero License Exam and he responds that he did not.

After that, Emi and Shota are seen sitting together on the bleachers of the Exam area, watching their respective students as the exam unfold, with Emi attempting to flirt with and tease Shota throughout the entire event. She comments on how every year, all the other schools gang up against U.A. students, though Shota insists that this does not matter. Emi notices that Shota's students were not fazed by the repeated attacks and overcame it. She continues to talk while remarking he hasn't not expelled any of his pupils at that point, and asks him if he is particularly fond of this year's class. While Shota replies that he is not, Emi does not seem convinced by his answer.

After the exam concludes with a substantial portion of both Emi's and Shota's classes passing, Emi suggests that they carry out joint training with both classes in the future and Shota agrees.
