She could also face challenges like dealing with new romantic interests from other characters who were just friends before. And the team dynamics would surely change, creating a lot of comical and heartwarming moments.
In a fanfiction where Kuroko turns into a girl, it could start with a mysterious event. Let's say there was a strange light that engulfed Kuroko during a game. After turning into a girl, Kuroko might struggle with her identity at first. She would have to deal with things like different clothing styles and the way people now interact with her. The story could explore how she still tries to contribute to the basketball team, even with this new form, and how her teammates support her through this strange transformation.
One idea could be that Kuroko turns into a girl due to a magical experiment gone wrong. His friends are initially shocked but then start to see the new 'her' as just Kuroko with a different appearance.

In a 'kuroko turns into a girl fanfic', perhaps there's a magical event that causes the transformation. Kuroko, as a girl, could discover new aspects of his/her personality.

Well, when Kuroko turns into a girl, it could lead to a whole new set of adventures. For starters, she would have to deal with the physical changes. Her voice might be different, and she would have to get used to the different body mechanics. In the story, this could be a source of humor as she tries to run or jump as she did before. Also, her relationship with the coach might change. The coach could be more protective or have different expectations of her. And the story could also explore how she copes with the reactions of fans, who might be very surprised to see this new version of Kuroko.
One possible plot twist could be how his relationships change. For example, his friends might react with shock and confusion at first. Mikasa might have a whole new set of emotions to deal with, like a different kind of protectiveness. Also, the military might view him differently. They could be hesitant to send a 'female - Eren' into battle at first, or they might use his new form to their advantage in different ways, like using his appearance to deceive the Titans.
Well, the plot could involve his teammates having to take care of him. They might struggle at first because Kuroko as a baby can't communicate in the same way. Maybe they have to figure out his needs like when he's hungry or sleepy. And they could also try to keep it a secret from the other teams to avoid any distractions during games.
His friends from his original life could be main characters. For example, if he has a best friend, that person would play an important role in helping Kuroko adjust to being a girl. Maybe they would offer support and advice, or just be there to listen when Kuroko has a tough time dealing with the changes.

Also, it could be that in this form, she discovers new aspects of her quirk that she was previously unaware of, but these new abilities come with a price. Maybe using them in this female form drains her energy faster or has some other negative side - effects.
Perhaps in a parallel universe, Superman is born as a girl. This version of her grows up with different experiences and challenges. She could be more in tune with female issues in society and use her powers to fight for gender equality as well as the usual superhero stuff like saving the world from villains and disasters.
Another possibility is that Finn - now a girl - discovers new powers or abilities that were hidden before. Since in many stories, a change in gender can sometimes bring out different aspects of a character.
