As the 5th Hokage, Naruto's relationship with the village elders would be complex. He'd have to assert his authority while also respecting their experience. Some elders who were against him in the past might now have to accept his leadership. With his sensei Jiraiya (if he were still alive), Naruto would have a different dynamic. He'd be able to show Jiraiya that he has grown into a great leader. And with the younger generation of ninjas, Naruto would be an inspiration. They'd idolize him and strive to be like him, which would in turn help Naruto in his goal of making the village stronger.
Naruto's relationship with the older generation like Tsunade would change significantly. Tsunade, being the former Hokage, would now be in an advisory role. Naruto would seek her advice on matters of the village's economy and long - term stability. With his peers like Kiba, Naruto would be more of a guiding figure. Kiba would look up to Naruto as the Hokage and might ask for more challenging missions for his growth. And with Hinata, their relationship could become more official. As Hokage, Naruto would have to balance his personal life with Hinata and his duties towards the village.
His relationship with Sasuke would likely become more of a partnership. They would work together to protect the village and the ninja world. With Sakura, Naruto might become more of a respected leader figure, and she could be one of his most trusted medical ninjas. And for Kakashi, Naruto would now be his equal in terms of leadership, and they would probably exchange ideas on how to better lead the village.
His relationship with Sasuke would be very different. Sasuke might see Naruto in a new light, perhaps with more respect as he's achieved the highest position in the village. Naruto would also have a different dynamic with Kakashi. He'd be more of an equal now, and Kakashi would have to adjust to Naruto being in a leadership role.
Her relationship with Naruto would likely become more of an equal partnership. Instead of Naruto being the main hero, they would share the responsibility of leading the village. They might have more serious discussions about village policies and strategies.
The dynamic would shift a bit. Naruto would have to balance his friendship with Sasuke and his duties as Hokage. He would probably try to bring Sasuke more into the fold of the village, making him feel like a true part of it. Sasuke, in turn, would start to see the village in a new light, through Naruto's leadership. Their relationship would be a key factor in the stability and growth of the village.
If Naruto travels back to the past, his relationship with his parents would be completely different. He would finally get to meet them as an adult and be able to have proper conversations with them. He could share his experiences and they could give him advice from their own wisdom.
For Naruto's relationship with Kakashi - sensei, Kakashi would be very observant. He would notice the changes in Naruto immediately and try to guide him. Since Naruto is now a Youkai, his interactions with his peers would be different. Some might avoid him out of fear, like Hinata who would be very shy and worried about this new Naruto. But Naruto's core values would still be there. So over time, as he proves that he's still the same person deep down, his relationships could start to heal and grow in new ways, even if his appearance and some of his powers are now different.
His relationship with Sasuke would likely become very strained. Sasuke, who has his own dark path, might still see Naruto's new Jashinist ways as too extreme. With Sakura, she would probably be very disappointed and try to convince Naruto to return to his old self. As for Kakashi, he would be deeply concerned and might even see Naruto as a potential threat to the village at first.
His relationship with his former sensei, Iruka, would be really interesting. Naruto could go back and show Iruka how much he has achieved, which would be a really heartwarming moment. And with Kakashi, he could share his experiences as Hokage and maybe even learn some new things from Kakashi in the past.
Naruto's personality might become more reserved in some ways. As Hokage, he has to represent the village in a more solemn and diplomatic manner. He can't be as carefree as he used to be. For example, in international meetings, he has to think carefully about his words and actions.
Regarding his friends like Shikamaru and Kiba, Naruto would be more accessible. As Hokage, he would be very busy, but without that role, he could spend more time with them. They could all go on more missions together as a team, strengthening their friendships in a different way than if Naruto was in a position of leadership.
