Inko Midoriya remains alive throughout the manga. The story doesn't involve her death. Her character plays an important role in supporting the protagonist without facing such a fate.
Midoriya would initially be in shock. But then, his heroic instincts would kick in. He might try to analyze Toga's behavior and find a way to use it against her. For instance, if he notices that she gets distracted easily, he could create a diversion. He would also be thinking about the safety of others. He might worry that Toga has some bigger plan that involves harming his classmates or the city. So he would be constantly looking for a way to not only escape but also stop Toga's potential evil plans. And throughout all this, he would be drawing on his training at U.A. to keep his composure and think rationally.
To write Aizawa well, focus on his stoic nature. Show his dry sense of humor and his no - nonsense approach to teaching and hero work. For example, when he interacts with Inko, he might be a bit gruff at first but then show his softer side over time. For Inko, emphasize her motherly love for Izuku. Let her be warm and caring, but also show that she has her own fears and insecurities. When writing their relationship, start with small exchanges, like a polite conversation at a school event, and gradually build the connection.
You can start by searching on popular fanfic websites like Archive of Our Own (AO3) or FanFiction.net. Just type in 'Izuku and Inko' in the search bar and you'll get a list of relevant fanfics. You can also check out some My Hero Academia fanfic communities on social media platforms. They often share and recommend great fanfics.
Midoriya's character development would be quite distinct. In his new form as a girl, he would have to re - evaluate his self - identity. He's always been a determined boy with a strong sense of justice. But as a girl, he might find that the world expects different things from him. This could lead to a struggle between his old self and the new self he's becoming. He might also develop a more nurturing side, which could enhance his hero capabilities in a different way. For instance, he could be better at calming down panicked civilians during a disaster. He would also have to deal with new forms of discrimination or assumptions based on his new gender.
There could be a sense of envy among some classmates. Just like how Todoroki has his own family issues related to his powerful father, Midoriya now has a connection to a respected teacher. This could cause some tension, especially if Midoriya starts getting special treatment from Aizawa during class or training.
For Izuku, his self - sacrificing nature can be further developed by putting him in situations where he has to choose between his own safety and the safety of others. This will show his growth as a hero. For Momo, her confidence can be explored more. Maybe she has to lead a team in a difficult task and overcome her insecurities. Inko's caring side can be developed by having her take in more characters who are in need, like an orphaned hero - in - training. This will show her as a mother figure not just to Izuku but to the whole community.
Another way her anger could manifest is by getting the school or other authorities involved. If Katsuki's actions towards Izuku are really bad in the fanfiction, Inko might go to the school principal or a hero agency to complain about Katsuki's behavior, hoping to get him to stop his mean - spirited actions towards her son.
To write a good Midoriya fanfic, first, understand his character. Know his values like his determination to be a hero. Then, create an interesting plot. For example, you could put him in a difficult situation he hasn't faced in the original story. Also, keep his voice consistent. He's usually quite positive and energetic.
