Consider Shinsou making a petition to change the way U.A entrance exams are set up, so no potential hero is ever denied the opportunity because of an unconventional quirk.
Initially, nobody really wants to sign it and he considers using his quirk to get people to sign it, but Deku convinces him otherwise.
On the other hand, Hatsume becomes the face of the petition, collecting over 100 signatures in a single day, and at least half of them are from faculty and upper year students. People gravitate towards her because of the sheer charisma she radiates. She drives a hard bargain convincing people that they’d benefit from an improved exam
Class 1-A and 1-B both have a competition to see who can gather the most signatures and Class 1-A wins, in large part to Momo and Kirishima. Kirishima is someone who is easy to get along with, and he has this way of making complete strangers feel like they’ve been life-long friends. Momo gathers more signatures because other students don’t have time to sign in between classes because all their pencils are packed up, and Momo never runs out of pencils.
When it comes time to present the petition at a staff meeting, Shinsou is a little nervous, but once he finishes presenting it and explaining how unfair the entrance exams are to people like him, Aizawa seconds it. The other heroes were considering it before, but Aizawa’s approval leads them to decide that the entrance exams need some changing. After all, approval from Aizawa doesn’t come lightly.
In the upcoming years, Shinsou works closely with the staff to make the exams more fair and Hatsume’s in charge of coming up with new ways of testing quirks.
In his final year, the first improved entrance exam is set to happen and Shinsou is with Present Mic, watching over the exams. There stands out a handful of students with enormous potential that would have never been recognized with the traditional exams. Afterwards, All Might stops Shinsou to speak with him and congratulates him, saying that a part of being a hero is challenging what others don’t.
