Well, without reading the fanfic, it's hard to say for sure. However, given the title, perhaps Mineta has done something to annoy Bakugou, like making inappropriate remarks or actions. Bakugou, being his hot - tempered self, decides to kick Mineta, and the window might be involved either as a target or as a result of Mineta crashing into it. It could also be part of a bigger story in the fanfic world where there are consequences and further developments based on this incident.
Since I'm not privy to the 'bakugou kick mineta window fanfic', I can only speculate. It could be that Mineta has been pestering Bakugou or another character, and Bakugou's way of dealing with it is by using force, in this case, a kick. The window might be a significant element, maybe it's a symbol of breaking boundaries or a physical obstacle that Mineta ends up interacting with in an unexpected way due to the kick. There could also be other characters' reactions to this event, which might drive the plot forward in the fanfic.
Well, it could be that Mineta was being his usual pervy self around the girls, and Bakugou, who can't stand such behavior, just snaps and kicks him out the window. Maybe Bakugou has been warning Mineta for a while, but Mineta doesn't listen. So in a fit of rage, Bakugou uses his explosive power to send Mineta flying out the window.
I'm sorry, I haven't read that specific fanfic, so I can't summarize it.
Kirishima would probably support Bakugou. He respects Bakugou's strength and no - nonsense attitude. He also doesn't like Mineta's pervy behavior, so he might think that Mineta deserved it. Kirishima would see Bakugou's action as a way to keep the class in line.
Well, perhaps Bakugo kicks Mineta towards a window out of anger. Maybe Mineta was up to his usual pervy antics and Bakugo just couldn't take it anymore. It could also be that they were in a fight over something silly like who gets the last piece of food, and Bakugo resorts to this extreme action.
Obviously, Bakugo and Mineta are the main characters. Bakugo is a very aggressive and competitive character, always striving to be the best hero. Mineta, on the other hand, is not as noble. He is often the source of comical and sometimes irritating situations. In this fanfic, their interaction, specifically Bakugo kicking Mineta towards a window, is the central focus.
It could be that Mineta was being cowardly during a mock battle. All Might has always emphasized the importance of courage in heroism. Mineta, being his usual timid self in the face of danger, decides to hide or run away instead of facing the 'villain'. All Might, disappointed in his lack of courage, yells at him. He tells Mineta that heroes don't run from challenges and that he needs to find the inner strength to face his fears if he ever wants to be a real hero.
Mineta could react with a mixture of embarrassment and defiance. He's a proud character in his own way. So when All Might yells at him, he might try to put on a brave face and argue back a little. But deep down, he knows he's in the wrong. Eventually, he'll break down and start crying, realizing that he has disappointed not only All Might but also his classmates who are all striving to be heroes.
Definitely the teachers. They would play a crucial role in the expulsion process. For example, Aizawa might be the one who has to enforce the decision. He's always been strict about behavior and academics in the classroom.
Mineta could be redeemed in a 'bnha mineta redemption fanfic' by having a character development arc. He might start to engage in more heroic deeds. Like, he could sacrifice his own safety to protect others during a battle. This would show that he is growing and becoming a better person, which would lead to his redemption.
Deku might be completely shocked at first. Since Bakugou has always been so aggressive towards him, he would never expect such a confession. He might just stand there, mouth agape, not knowing what to say.
