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.
One idea could be a story about Sarada training with Sakura and Sasuke. Sarada is eager to learn new jutsu and Sakura teaches her some medical ninjutsu while Sasuke shows her some of his signature moves. This would be a great way to explore the family dynamic and how Sarada grows as a ninja with the help of her parents.
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.
In a fanfiction set in an inn, Itachi might be there to pass on some crucial information to Sasuke and Naruto. He could choose the inn as a neutral and unexpected place. Sasuke would be hesitant to trust Itachi, but Naruto's presence might make him more receptive. They could engage in a battle of ideologies, with Naruto representing hope and friendship, Sasuke representing vengeance and Itachi representing sacrifice. The inn becomes the backdrop for this intense encounter.
A possible fanfic could focus on a parallel universe where Itachi and Sasuke are not bound by the same clan conflicts. In this universe, they could meet in a more peaceful setting, like a small village. Their relationship could develop gradually as they discover shared interests. For example, they might both be interested in learning about ancient ninja arts, and through this common ground, a yaoi - inspired relationship could start to form.
First, focus on the relationships. The relationship between Sasuke and Sakura, which has its own history of love and misunderstandings, and the relationship between them and Sarada, which is full of parental love and the hope for the next generation. Develop their personalities well. Sasuke's brooding nature, Sakura's strength and kindness, and Sarada's determination.
One possible plot could be Sarada's training journey with Sasuke. Sasuke, being a highly skilled ninja, could be teaching Sarada some advanced jutsu. Meanwhile, Sakura, as Sarada's mother, could be worried about her daughter's safety during the training. This could lead to some family - oriented drama where Sasuke has to assure Sakura that he'll take care of Sarada.
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.
