In the fanfiction, perhaps Stain trains Izuku because he believes Izuku has the purity of heart to use power in a way that Stain deems correct. Stain could teach Izuku how to analyze opponents better, which would enhance Izuku's ability to strategize in battles. Izuku might then start to question the current hero ranking system during his training. He could grow to be a hero who is more focused on the essence of heroism rather than just fame and recognition, which would make him stand out among his peers and also cause some friction with the more traditional heroes and hero agencies.
One possible plot could be that Izuku discovers Rei's hidden strength. Maybe Rei has some untapped quirk potential that Izuku, with his analytical mind, helps her realize. They could team up to face a new threat in the My Hero Academia world that requires both of their unique skills and experiences.
Maybe the fanfiction could focus on Eri's growth under Izuku's care. She starts to see herself as a normal girl with a powerful quirk, not just a tool. Izuku helps her with her schoolwork, they cook together, and he tells her stories about All Might. As time passes, Eri becomes more confident and starts to think about how she can use her quirk to help others, just like Izuku does. She might even start to train to become a hero herself one day.
