His friends like Sasuke, Sakura, and Kakashi would surely support him. They have been through a lot together and know Naruto's good heart and leadership potential.
I think the whole of Team 7 would be behind him. Sasuke, despite his past, would see Naruto's potential as a Hokage and support him in his own way, perhaps by helping to protect the village from external threats. Kakashi, as Naruto's former teacher, would also be there to guide him in the early days of his Hokage - ship.
I think the whole of Team 7 would be in full support. Sasuke might return to the village and support Naruto as he sees Naruto's growth and leadership potential. Kakashi would also be there to guide Naruto as he steps into the role. Additionally, the people of Konoha who have seen Naruto grow from an outcast to a hero would be very likely to support him as their new Hokage.
His friends like Sasuke would most likely support him. Sasuke, having walked a long path of redemption, would see Naruto's vision of an empire as a way to finally achieve the peace they both have been longing for.
I think some of the younger ninjas in the village would support Naruto. They look up to him as a role model. Also, those who have been helped by Naruto in the past, like the families of the villagers he saved. They would see that Naruto is fighting for what's right and would stand with him against the council. Additionally, some of the outcast ninjas who feel oppressed by the council's rules might also join Naruto.
The villagers of the Land of Waves would surely support Naruto. They have suffered a great deal under Gato's rule, so they would see Naruto as their savior. Also, Sasuke might support Naruto. Even though they have their differences, Sasuke would recognize the need to stop someone as evil as Gato.
His closest friends like Sasuke would most likely support him. Sasuke, who has also seen the dark side of the shinobi world, would understand Naruto's reasons for rebellion. Also, Sakura, who has always been by Naruto's side, would be there to support him. Shikamaru, with his intelligence, might also see the need for change and back Naruto up.
I think the nature spirits might support Percy. Since Percy has a connection with water and nature in general, they would see him as a more benevolent leader compared to the current gods. Also, the mortals who have been saved by Percy in the past would probably be in favor of him becoming the king of gods. They believe he would use his power to protect them and make their lives better, rather than just for the gods' own amusement or self - interest.
In this fanfiction, Naruto would interact with Vesemir, the old and wise Witcher. Vesemir could see Naruto's potential and help him understand the history and traditions of the Witchers. Naruto would also run into the various monsters in the Witcher world. Instead of just fighting them right away, he might try to communicate with them first, like he did with some of the tailed beasts in his own world. His interactions with these creatures would be unique and could even change the way Witchers view certain monsters.
Sakura might support Naruto. She has always believed in Naruto and his ability to do the right thing. So when he becomes the leader of Root, she would see it as an opportunity for Naruto to bring positive change. She could offer her medical skills to help the Root members who may be injured during the transformation of the organization.
Sakura would probably support Naruto marrying Yakumo. She has grown to be a good friend of Naruto over the years. She knows Naruto's big heart and when she sees how much he cares for Yakumo, she would be on board. Shikamaru, despite his laziness, would also offer his support. He is perceptive and can tell that Naruto and Yakumo are good for each other.
