In a 'Takasu becomes a girl' fanfic, Takasu could start to notice how differently people treat her. Guys might start to be more chivalrous or flirtatious, which she's not used to. She could also use her new - found femininity to her advantage in some situations, like getting better grades by charming a teacher. But at the same time, she might struggle with the idea of losing her masculinity - related skills, like her strength, and have to find new ways to be confident in herself.
Well, perhaps Takasu as a girl could join a female - dominated club at school. This would lead to her making new friends and experiencing a different side of school life. She might also face some challenges in her relationship with Ryuuji. Since she's now a girl, their friendship could shift into a more complex dynamic, with Ryuuji seeing her in a new light and Takasu having to figure out her own feelings for him in this new form.
Takasu's character development would likely be very different. As a girl, she'd have to face different types of insecurities. For example, she might worry more about her appearance or how she's perceived by others. Her relationships with the other characters would also change. Instead of the typical male - female friendships she had before, she'd be in a different social position. She might become more self - conscious about her actions and how they affect those around her.
One possible plot could be that Ryuuji wakes up one day as a girl. He, now she, has to deal with the reactions of her friends like Taiga. Taiga might initially be shocked but then grow more protective. Ryuuji would also have to adjust to new social dynamics at school, like how the boys interact with her now and how she fits in with the girls. She might struggle with wearing different clothes and having different expectations placed on her.

Since she's a girl, she might approach the mental and physical aspects of transformation in a new way.
One possible plot point is how Deku as a girl interacts with female characters. She could form new friendships or rivalries with them. For instance, she might bond more closely with Uraraka now that they share the same gender. And in terms of her hero training, she may face different challenges and opportunities compared to when she was male.
Perhaps an old acquaintance of Ryuuji's who has some unresolved issues with him. When Ryuuji turns into a girl, this person sees it as an opportunity to get revenge in a more devious way.
