If Naruto pretends to be a boy in a fanfiction, his relationships would be quite different. His bond with Jiraiya might become even stronger as Jiraiya could see this as an opportunity for Naruto to learn more about the male - dominated ninja world from a different perspective. Naruto's relationship with the villagers could also change. Some of the older villagers who were previously skeptical of Naruto might view him differently as a 'boy'. They might be more accepting or even start to respect him more. And with his peers, like Choji, Naruto might find himself involved in more typically 'male' activities like roughhousing or competing in strength - based games, which could either strengthen or strain their relationships depending on how well Naruto can keep up his act.
Well, Naruto's relationship with his male friends would take on a new dynamic. For example, Shikamaru might be less dismissive of 'male' Naruto as he might expect different behavior from a boy. Naruto could also get closer to some of the more reserved male characters who usually keep their distance from girls. On the other hand, his relationship with female characters like Ino could become more complex. Ino might be intrigued by this new 'boy' in town and try to figure out what makes him different. And Naruto would have to constantly balance his real self and his pretend self in all these relationships.
His relationship with Sasuke would likely be very different. Since Sasuke has also had experiences with the Rinnegan, they might now have a new level of understanding between them. They could train together to master the powers of the Rinnegan or compare notes on how to use its abilities.
With Kakashi, Naruto's relationship would also shift. Kakashi has had experience with the Sharingan and knows about powerful dojutsu. He would be both amazed and a bit worried about Naruto having the Rinnegan. He might try to mentor Naruto more intensively to make sure he uses it for good and doesn't let the power corrupt him. Naruto would look up to Kakashi even more as he tries to learn about his new power from Kakashi's knowledge.
His relationship with Jiraiya would be different. Jiraiya trained Minato, but with Naruto replacing Minato, Jiraiya might train Naruto even more intensively from an earlier age. Naruto would also probably be more open with Jiraiya about his feelings and plans, as he's not as reserved as Minato.
His relationship with Sasuke would be extremely complex. Sasuke, who has his own vendetta against the shinobi world, might initially be suspicious of Naruto's new role. But Naruto, as the Akatsuki leader, would try to convince Sasuke to join him in his new vision for the organization. It could be a love - hate relationship where they constantly butt heads but also understand each other on a deeper level.
His relationship with Sasuke would be very different. Instead of being rivals, they might become more like comrades or even brothers in arms, as Itachi and Sasuke were related. Naruto would probably be more understanding of Sasuke's thirst for power and revenge, and might try to guide him in a more Itachi - like way. With Sakura, Naruto might become more distant, as Itachi was not very close to female characters in the original story. And with his other friends like Shikamaru or Kiba, Naruto would likely be more reserved and less of the loud, exuberant self they knew, which could cause some confusion and concern among them.
When it comes to his friends like Shikamaru and Choji, Naruto might distance himself from them. Zabuza is a loner, and being raised by him, Naruto could start to prefer solitude. He might not value the group dynamic as much as he does in the original story and instead focus on his own strength and survival skills.
His relationship with Sasuke would be really interesting. Instead of Sasuke being the only one with the Sharingan, Naruto now has it too. Sasuke might feel a mix of envy and camaraderie. Envy because Naruto has something that was so much a part of his identity, and camaraderie because they now share a powerful ability.
His relationship with Sasuke would be very different. Instead of seeing Sasuke as a rival and a friend, he might view him as a potential threat to the village from the start. With Sakura, he may not be as friendly or protective. His bond with Kakashi would likely be non - existent or at least very strained, as Danzo and Kakashi have different outlooks. Naruto would probably be more isolated from his peers, as Danzo's upbringing would make him more guarded.
His relationship with Sasuke would be drastically different. Instead of being rivals from the Leaf Village, they could be on opposite sides. Sasuke might see Naruto as a traitor to the Leaf and Naruto might see Sasuke as someone who doesn't understand the Akatsuki's motives. With Sakura, Naruto might not have the same protective feelings. He could view her as just another ninja from a village that the Akatsuki has issues with.
His relationship with Sasuke would likely be very different. Sasuke, who is used to Naruto as a boy, might be initially confused and a bit off - balance when Naruto becomes a girl. He might see Naruto in a new light, perhaps feeling more protective or having a different kind of rivalry. With Sakura, they could become closer as 'sisters' or girlfriends in a sense. Sakura might start to confide in Naruto - as - a - girl more, sharing things like her insecurities about her looks or her feelings for Sasuke. And with Kakashi, he would probably be amused at first but also keep a close eye on Naruto to make sure he doesn't get into too much trouble while in his new form.
