One possible plotline could be that Itachi sees Naruto's potential even at a young age. He might start teaching Naruto basic ninja skills like stealth. For example, Itachi could show Naruto how to move quietly in the forest without making a sound. This early training could give Naruto an edge when he later enters the academy, as he would already have a foundation in some ninja arts.
Maybe Itachi trains Naruto in chakra control. He could teach Naruto how to climb trees using chakra, which is a fundamental skill. This would make Naruto more confident and advanced compared to his peers when he starts at the academy. Also, Itachi might pass on some of his knowledge about the Sharingan, not the ability to use it, but how to recognize and counter it. This would be very useful for Naruto in future battles against Uchiha opponents.
Itachi could also train Naruto in terms of mental strength. He might tell Naruto stories about the harshness of the ninja world and how to face difficulties. This would shape Naruto's mindset early on. For instance, Naruto would learn not to be afraid of strong opponents but rather see them as challenges to overcome. In the fanfiction, this early training by Itachi could lead to Naruto being a more well - rounded ninja by the time he enters the academy, and it could also change the way some of his classmates and teachers perceive him.
Naruto might be more confident in his relationships. Since he has received training from Itachi, he would be more self - assured. He might not be as eager to prove himself in a brash way as in the original story, which could lead to better relationships with his classmates. For example, he wouldn't constantly challenge Sasuke in a show - of - strength manner.
One possible plotline could be the challenges they face in a world that might not be accepting of their relationship. With Itachi being pregnant, they have to deal with secrecy and the potential danger that could come to their unborn child from various forces in the Naruto universe.
In this fanfiction, Itachi might also train Naruto in the ways of the Sharingan. Even though Naruto doesn't have the Sharingan naturally, Itachi could find ways to make Naruto understand the principles behind it, like how to read an opponent's movements more accurately. This could lead to Naruto having an edge in battles against opponents who rely on speed and deception.
One possible plotline could be that Naruto is forced into a situation where he has to kill Itachi to protect the Hidden Leaf. Maybe Itachi is being controlled by some dark force and Naruto, with great reluctance, has to end his life to save the village and his friends.
A plotline might involve the two of them in a world where gender roles are more fluid. Effeminate Naruto and fem Itachi could be part of a mission together, and during the process, they discover new aspects of each other's personalities. For example, Naruto's kind - heartedness and Itachi's hidden soft side. Their relationship could develop from mutual respect to something deeper as they face various challenges. And perhaps they have to deal with the reactions of their friends and the ninja community to their relationship, which adds more drama to the story.
One possible plotline is that Fem Naruto and Itachi are assigned to protect a valuable village asset. Along the way, they face numerous enemies and have to work together to overcome them. As they fight side by side, they start to respect each other's abilities more.
One possible plot could be that Itachi, seeing Naruto's potential and his importance for the future of the Hidden Leaf, decides to secretly train him. Itachi might teach Naruto advanced jutsu, especially those related to chakra control and unique Sharingan - inspired techniques. Naruto, under Itachi's tutelage, would grow not only in power but also in his understanding of the ninja world's complex politics and the Uchiha clan's history.
Perhaps Sakura gets into trouble during a training exercise and Itachi has to rescue her, which then leads to a more intense and focused training regime. Another development could be that Sakura starts to think like Itachi in battle situations, using his tactics to outwit her opponents. It could also be that as she gets stronger, other characters start to notice and either become jealous or try to recruit her for their own purposes.
One possible plotline could be that they got married to form an alliance between two powerful factions secretly. Another could be that they fell in love while on a secret mission together that no one else knew about. Maybe Itachi was on a mission to protect Naruto from afar and they developed feelings over time.
One possible plotline could be that Naruto is somehow tricked into leaving with Kisami and Itachi. Maybe they convince him that there is a greater threat that only they can help him face. Along the way, Naruto might start to learn more about their motives and the secrets of their pasts. He could also be in a position where he has to use his own skills and values to influence them.
