Another storyline could be a time - travel fanfiction. Sakura somehow travels back in time and meets a young Itachi. She tries to prevent the Uchiha massacre by working with Itachi. In this process, she might also learn more about the Uchiha clan and their secrets, which she can later use to help Naruto in their present - day battles.
One interesting storyline could be a story where Sasuke, Naruto and Itachi have to team up against a new, powerful enemy. They put aside their differences and combine their unique skills. Naruto's positive energy and powerful jutsu, Sasuke's sharingan - based techniques, and Itachi's strategic mind make them a formidable force. This kind of story could explore their growth as characters and how they learn to trust each other more deeply.
In a more complex story, Female Itachi could be part of a prophecy related to Naruto. The two of them are fated to join forces to defeat a greater evil. Their journey involves them learning about each other's powers and pasts. Female Itachi might have her own secrets about the Uchiha clan that she reveals to Naruto as they grow closer in their fight against the common enemy.
One interesting storyline could be Sakura joining the Anbu and having to prove herself among the male - dominated group. She might face challenges like secrecy requirements and intense training, all while Naruto is on his own journey, and their paths cross in unexpected ways during missions.
Perhaps in the fanfiction, there is some sort of magic or jutsu gone wrong. Itachi and Sakura are affected by it, and this leads to Sakura's pregnancy. They might then struggle to understand what has happened and how to move forward, especially considering Itachi's complex past and Sakura's own goals and dreams.
Another storyline could revolve around a promise they made as children that they forgot over time. As they grow older and face different challenges, something triggers their memory of that promise. It could be a place or an item. Then they have to figure out what the promise meant and how it still holds significance in their current relationship, whether it's a promise of friendship or something more.
Another storyline could be a training - arc - like fanfiction. Maybe Naruto wants to teach Hinata and Sakura a new jutsu he learned. Hinata might struggle a bit more because of her gentle nature compared to Sakura's more assertive learning style. They could all learn from each other's strengths and weaknesses during this training, which would also strengthen their bonds as friends and comrades.
Well, in some fanfics, Sakura goes on solo adventures to discover new medical techniques. For example, she might travel to a far - off land where there are rare herbs that can enhance her healing abilities. Another storyline could be her training with a mysterious master who teaches her unique combat skills that she can use in battles.
Well, in some fanfictions, Itachi might seem to be cheating on Naruto in the sense that he's forming closer alliances with other characters for strategic purposes. For example, he could be getting involved with another ninja clan to gain information or resources for the greater good, but Naruto misinterprets his actions as being unfaithful in their friendship.
One possible storyline could be that it's a result of some strange jutsu gone wrong that binds their fates in this unexpected way. They then have to deal with the reactions of their friends and foes alike. For example, Naruto might be shocked at first but then supportive, while Sasuke could be more conflicted given his relationship with Itachi.
One interesting storyline could be a story where Naruto has to choose between Hinata and Ino Sakura. Maybe there's a mission that reveals different sides of their characters and makes Naruto question his feelings. For example, Hinata could show great courage in protecting Naruto during a dangerous part of the mission, while Ino Sakura displays her intelligence in solving a complex riddle that helps the team. This creates a dilemma for Naruto as he realizes how important both of them are to him in different ways.
