If Naruto becomes a Jounin in the fanfic, his relationship with the village elders would be complex. On one hand, he would be respected for his new rank and power. On the other hand, he might face more scrutiny as he has his own ideas about how the village should be run. His relationship with the other Jounin in the village would also change. He would be part of their group now, and they would expect him to uphold the standards and traditions of the Jounin rank.
Naruto's relationship with the younger generation would be very different. As a Jounin, he would be a role model. The kids in the village would look up to him even more. He could inspire them to work hard. His relationship with Hinata might also evolve. Maybe he would finally have more time to focus on their relationship now that he has achieved a higher rank and more stability in his ninja career.
His relationship with his old friends like Sasuke would likely become more of an equal partnership. Since they are both highly skilled, they could collaborate on important missions. With Sakura, he might be seen as more of a respected colleague, and she could look up to him in a different way as a Jounin.
In terms of his romantic relationships, if there was a budding relationship with Hinata, for instance, his new status as a jounin could either strengthen their bond as she admires his achievement, or it could create some distance as he has more duties and less time for personal matters.
With his friends, he would still be close, but there would be a new level of respect. They would see him as a more experienced and powerful shinobi. For example, Sasuke might have a different kind of rivalry with him, one that is more about mutual growth at the Jounin level rather than just power struggles. Naruto's leadership skills would also be more prominent in group situations, which could change the dynamics of his relationships with his friends.
His relationship with Sakura would change a lot. Sakura might be more protective of Naruto as a cat, seeing him as a cute and vulnerable creature. She might take on a more motherly role towards him. With Kakashi, Kakashi would probably be amused by Naruto's cat form at first, but then he'd start to worry about how to turn him back. And as for his friends in general, they'd have to communicate with him in different ways, like through body language and meows.
His relationship with Sasuke would be greatly affected. Sasuke might see Naruto as a completely different person now that he has become the Nine - Tails. There could be a sense of fear or at least a new level of caution from Sasuke. They might have to re - establish their bond, as Naruto's new form could be a threat in Sasuke's eyes.
Naruto's relationship with his students, if he has any as a Jounin, would be very important. He would be a mentor figure. He would have to be strict but also kind, just like Kakashi was to him. He would pass on his values and ninja techniques. His relationship with the Hokage would also be different. He would be closer to being an equal, having more say in important decisions regarding the village's security and future.
His relationship with Sakura would be very different. Instead of the old friendship/romantic tension, Sakura might be initially afraid of him as a vampire. She would have to overcome her fear and see that Naruto is still the same person inside. His relationship with Sasuke could also be strained. Sasuke might see Naruto's transformation as a sign of weakness or a new threat.
If Naruto becomes a Jounin early in fanfiction, his relationship with his peers might change. They could look up to him more, seeing him as a role model. His friends like Sasuke might be a bit jealous at first but would also be proud. His relationship with his teachers could shift as he is now closer to their rank.
His relationship with Sasuke would be really interesting. Since Sasuke has his own complex connection to the Uchiha clan and Madara, Naruto becoming a Madara fan could either bring them closer together in understanding the Uchiha's past or drive them further apart if Sasuke doesn't agree with Naruto's new - found admiration. Maybe Naruto would start to push Sasuke towards a more 'Madara - like' view of power and revenge.
His relationship with Sakura would change a lot. Sakura might be initially scared of Naruto's fox form, but as she realizes it's still him inside, she would start to see him in a new light. She could become more protective of him. With Kakashi, Kakashi would be more cautious and observant, trying to figure out how to help Naruto control his new form. And with his rivals, they might either be more envious or more afraid of him now that he has this unique transformation.
