The Uchiha might initially be filled with anger. Their trust in Naruto, if it was there before, would be completely shattered. They could start to plot revenge against Naruto, believing that he has wronged them. This could lead to a lot of tense moments in the fanfiction as the Uchiha gather their strength and resources.
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.
One idea could be that Sarada travels back in time and initially mistakes Naruto for Sasuke. This could lead to some humorous misunderstandings as she tries to interact with him. For example, she might challenge him to a fight thinking he's Sasuke, only to be completely surprised by Naruto's different fighting style and personality.
There are several potential great fanfics. For example, a fanfic could center around Sarada's search for her father's true self. She might go on a journey to understand Sasuke better, facing various challenges along the way. It could also delve into her relationship with her mother, Sakura. This type of fanfic would give a lot of insight into Sarada's character and her place in the Naruto Gaiden storyline.
One possible scenario could be that Sarada is initially in awe. Meeting the Uchiha clan, she might feel a strong sense of belonging. She could discover new jutsus that were unique to the clan and passed down through generations. This would not only enhance her skills but also give her a deeper understanding of her heritage.
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 She could become withdrawn for a while, not wanting to talk to her friends about it.
Obviously, Sarada Uchiha herself is a main character. Often, her parents, Sasuke and Sakura, are also prominently featured. Boruto Uzumaki might also be involved as he is Sarada's peer and they often interact in the Naruto universe.
One popular plot theme could be Sarada learning valuable life lessons from Naruto. Since Naruto has been through so much and has a wealth of experience, he could mentor Sarada. For example, he might teach her about perseverance in the face of difficult missions or how to handle the pressure of being from a well - known ninja clan. Another theme could be a time - travel plot where Sarada goes back in time and witnesses Naruto's journey from the start, which gives her a new perspective on her own life and goals. Also, a plot about Sarada and Naruto teaming up to face a new, powerful enemy that threatens the Hidden Leaf Village would be interesting. They could combine their unique skills, like Sarada's Sharingan - based abilities and Naruto's Nine - Tails chakra, to defeat the foe.
