After reading Rei's profile, I have to know how Midoriya and Todoroki learn about her behavior and react to it
That particular scene is very up in the air, but here is what I have.
So after battling Taboo (main antagonist, mad scientist who uses her quirk to combine quirk genetics to make society destroying monsters. There is a lot with her, but I won't go in on that.) during like the maybe story midpoint. At the end of fight, the ShunCrew reunite after being separated and are very happy about it. This is in the presence of multiple heroes and their classmates.
Now the lead up to how the conversation goes is fuzzy, but Rei eventually says something along the lines of the ShunCrew should have committed suicide long ago because they are from unheroic backgrounds and Rei is very much a my hero version of classist.
As soon as those words leave her mouth, several things happen.
Everyone in the room is horrified (rightfully so) and none are so more horrified as Midoriya and Todoroki who are so shocked that it allows time for Iori Kano to verbally beat Rei Midoriya down and complete his character arc. As soon as they are awake from their stupor though, they immediately take Rei and leave. They apologize to the ShunCrew then just bolt with her in tow.
You don't really see the conversation between them, but Rei Midoriya does NOT return to UA or Ultra Academy. In fact, her dorm is stripped barren, her locker in the hero changing room is completely cleaned up, her desk is cleaned out, like she is GONE. Their teacher (who I haven't decided who it is but I am leaning towards Kendo) tells the class that Rei has left.
Now for you, I'll explain what happened.
Upon leaving, Midoriya and Todoroki are dead silent in the car and Rei senses she has done something wrong but doesn't understand what. As soon as they get home, Midoriya runs off to cry (He may have gotten therapy for those quirkless years but having your own child rip those open is not fun) and Todoroki sends Rei to her room. Rei tries to text her former friend Isao, but isao basically tells her to fuck off and then blocks her number and her social media accounts. She later learns that every other classmate has as well.
The next day, the house is still quiet and Rei is very upset about that because Midoriya and Todoroki take shfits watching her as they go off. Her parents are collecting formal accountants of what Rei has done, and are growing more and more upset.
After a week of this uncomfortable silence, Rei is finally sat down and told that she will be removed from UA because she can either be expelled or leave and her parents chose her leaving. Rei will be forced to partake in charity work, and attend a normal university. Rei is very upset about this, and fights with her parents all the way about it.
Now at some point in her profile, I mentioned that she refuses for her story to be over and I mean it. Rei starts participating in a normal life, but she refuses to give up on become a hero... even if she has to do it illegally.
That is right, it is vigilante Rei time.
The idea of vigilante Rei is that she finds another way to become a hero, a more spiteful way but a way. While she works as a vigilante she starts to meet other vigilantes, and kind ends up being forced to see the world through those effected by the police brutality and quirk bias caused by the KiriBaku Scandals.
