Sarada might be initially shocked and sad. She loves both her parents, and the divorce would be a huge blow to her. She could become withdrawn for a while, not wanting to talk to her friends about it.
She might inherit Naruto's blond hair and blue eyes. Since Naruto has a very distinct look, it's possible that Sarada would have some of his features. Maybe she would still have some Uchiha traits as well, like the Sharingan. But overall, she could look more like Naruto with a bit of an Uchiha touch.
One possible plot could be that they are on a mission together in a dangerous situation. As they face numerous challenges and rely on each other for survival, their bond deepens. In a moment of intense relief after narrowly escaping death, they share a spontaneous kiss. It could be a story about two characters from different backgrounds coming together through shared experiences.
Itachi would probably be very calm and composed. He might see Sarada as a symbol of the new generation of ninjas in the village. He could be gentle with her, perhaps sensing her potential and her desire to grow as a ninja.
There's also a chance she meets her own ancestors. This would be a very emotional and educational encounter for her. She could learn about her family's past in a more direct way and maybe discover some long - lost family secrets.
Sarada's relationships would change. If she meets her ancestors or younger versions of people she knows, she'd have to navigate new dynamics. For example, if she meets a young Sakura, she might initially be in awe but then realize that her mother was also a normal ninja once. This would make her respect Sakura even more and also change how she views herself as part of their family legacy.
A possible relationship could be one of mutual respect. Sarada would respect Itachi for his skills and his past sacrifices. Itachi, on the other hand, might see Sarada as a symbol of hope for the future of the Uchiha clan. They could share stories about the Uchiha, with Itachi passing on the history and traditions that Sarada might not be fully aware of. This could strengthen their bond and lead to a deeper understanding between them. In the fanfiction, they might also team up to face a common enemy, relying on each other's strengths and abilities, which would further solidify their relationship.
