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.
Sakura would be a great addition. As Sarada's mother, she could add an interesting dynamic. Also, Boruto could be included. His relationship with Sarada and his own skills could create some engaging storylines. Another good character could be Kakashi. His wisdom and combat experience could be useful in the story.
There could be Sasuke. Since Sarada is his daughter, he might be in the background, either not aware of the encounter yet or on his way to find Sarada. Naruto could also be a character. He has a connection to both Itachi and Sasuke, and he might play a role in the events that lead up to or follow the encounter. Another possible character could be Sakura. As Sarada's mother, she would be worried if Sarada was out of her sight and her actions to find Sarada could be part of the story.
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 She could become withdrawn for a while, not wanting to talk to her friends about it.
One potential antagonist could be a group of rogue ninjas who see Sarada's pregnancy as a sign of weakness in the village. They might try to target her to cause chaos. Another could be a jealous rival who doesn't like the attention Sarada is getting due to her pregnancy and her connection to Naruto.
Well, Sasuke, of course, is a key figure. He has been through a lot, from his time as a rogue ninja to his redemption. Sarada, on the other hand, is a young and determined ninja - in - training. She is constantly seeking to prove herself and to get closer to her father. In this fanfiction, their interactions will likely be the focus, with both of them evolving as characters through their meetings.
Obviously, the main characters are Sarada and Sasuke. Sarada, being Sasuke's daughter, has a lot to learn from him. Their relationship forms the core of this fanfiction.
Perhaps there are some anti - Uchiha elements within the village that are not happy with Naruto adopting Sarada. They could try to undermine her training or create problems for Naruto and Sarada. They might spread false rumors or try to isolate Sarada from the rest of the village.
Maybe an enemy from another village. If there are political tensions between villages, kidnapping Sarada could be a way to gain an advantage. They might think that by having her, they can force her village to make concessions in treaties or resources.
