With Sakura, Naruto might not be as much of a bumbling suitor. His time with Totosai could have given him more confidence and a different kind of maturity. He might see Sakura more as a teammate with whom he can share his knowledge of weapon - making and other skills he learned from Totosai, rather than just having a one - sided crush.
His relationship with Sasuke would be different. Instead of the intense rivalry based on power and recognition, it could be more about their different approaches to protecting the village. Naruto, with his skills from Totosai, might offer Sasuke unique weapons or tools to aid him in his missions.
His relationship with Kakashi would also change. Kakashi would be more curious about Naruto's new skills and how they could be integrated into the team. Naruto might look up to Kakashi less for his combat skills and more for his leadership, as Naruto has his own set of skills from Totosai that are quite distinct.
His relationship with Sasuke would likely be very different. Without the shared experiences in Konoha, their initial rivalry might not be as intense. Naruto might not be as desperate to bring Sasuke back. And his relationships with his other Konoha friends like Sakura and Kakashi would also change. He'd be more connected to Yugito's friends and allies instead.
The story might focus on how Naruto's upbringing by Totosai changes his personality. Instead of being the boisterous and food - loving Naruto we know, he could be more introverted and focused on his craft. However, his core values of loyalty and protecting his friends would still remain, and he would use his new skills to protect the village in a different way.
If Naruto was raised in a Jinchuriki Sanctuary in fanfiction, his relationships would undergo a significant transformation. First of all, he would have a group of peers who are also Jinchurikis. This would create a sense of camaraderie that is based on a mutual understanding of the unique challenges they face. His relationships would not be marred by the fear and prejudice that he faced in Konoha. Instead, they would be built on mutual respect and the common goal of mastering their Jinchuriki powers. He might form closer bonds with some Jinchurikis who could become like family to him. And in terms of romantic relationships, he could potentially find a partner who not only accepts him but also shares his powerful and complex identity as a Jinchuriki.
His relationships would be drastically different. For example, his relationship with Sasuke would be strange. Sasuke might be both intrigued and scared of Naruto's new powers. And Naruto might not have the same bond with his original friends from the Leaf Village as he's now more in the vampire world.
His relationship with Sasuke could be different. Maybe Sasuke would be in awe of Naruto's new powers at first. They might have less of a rivalry and more of a partnership from the start, with Sasuke seeing Naruto as a step ahead in power and knowledge.
His personality might be more serious. Since Onoki is a no - nonsense leader, Naruto could pick up that trait. He might be less impulsive and more calculating in battles.
Naruto could be more empathetic towards the Uchiha's cause. Since Mikoto is his mother figure, he would be exposed to the Uchiha's history and their grievances from a young age. This would make him more understanding of Sasuke's later actions and more likely to try and find a peaceful solution for the Uchiha's problems.
Naruto might be more knowledgeable about the history and politics of the village. Hiruzen, being the Hokage, would surely educate Naruto on such matters. This would make Naruto more diplomatic and better able to handle complex village - related issues. He would also be more respectful of traditions and the hierarchy within the village, having been raised by the village's leader.
He might be more aloof. Since a phoenix is a rather otherworldly creature, Naruto could pick up some of its more detached qualities. He may not be as quick to make friends as in the original story, instead observing more from a distance before approaching others.
Naruto's story would be different in terms of his upbringing. Instead of the loneliness he faced in the original, with the Yamanaka, he might have a more family - oriented environment. He could be taught the values of the Yamanaka clan from an early age.
