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.
At first, it could be a bit awkward. Sarada has only heard stories about Itachi. But as they start to interact, they might develop a mentor - mentee relationship. Itachi could see Sarada's potential and start to guide her.
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.
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.
Well, perhaps Sarada could be initially in awe of Itachi. She might learn some unique jutsu techniques from him in the fanfiction. It could also be a scenario where Itachi gives her some sage advice on how to handle her own powers and responsibilities within the Uchiha clan.
Itachi's skills and wisdom would no doubt rub off on Sarada. His combat expertise and his way of thinking could give Sarada new ideas on how to approach battles and solve problems. This would make her a more well - rounded and formidable ninja, thus contributing to her growth in the ninja world.
In a Sarada meets past Sasuke fanfiction, it could be that Sarada has to keep her identity a secret at first. She might be on a mission in the past for some reason. As she observes past Sasuke, she could notice his skills and the way he interacts with others, like Naruto. This would give her a chance to understand the bond between her father and Naruto from a whole new perspective, which could be really interesting for the readers.
One great Sasuke, Sakura, Sarada fanfic is 'A Family's Bond'. It beautifully portrays the family dynamics between them. The story shows Sasuke's growth as a father, Sakura's strength as a mother, and Sarada's journey to understand her family better.
One idea could be a story where Sasuke takes Sarada on a special training mission, much like how his father might have trained him. Sakura could be worried at first but then see how Sarada grows from the experience.
In the fanfiction, the interaction between Sarada and Sasuke's family could be filled with emotions. Maybe Sasuke's family has high expectations of Sarada, given her relation to Sasuke. This could create some tension at first, but as they get to know her better, they start to accept and love her.
