Sasuke could also be a main character. Even though he has his own path, his relationship with Naruto is so deep that he would surely be involved in Naruto's life as the Hokage. He might offer his support or advice when Naruto faces difficulties. And Kakashi, as Naruto's former teacher and the previous Hokage, could also be a key figure in the story.
Other characters like Shikamaru, who has always been Naruto's friend and a strategic thinker in the village, might also be a main character. He could be Naruto's right - hand man, helping him with the administrative tasks and coming up with plans to deal with various threats to the village.
Well, Naruto himself is likely to be there as he is an important part of the Naruto universe. Sakura might also be a common character. Since she has a long - standing relationship with Naruto and other characters in the series. Hinata could also be featured as she has her own connection to Naruto. These characters can be involved in the 'lemon' aspects, like perhaps a love story between the 6th Hokage and one of them.
Naruto himself could be a likely candidate. Given his strength, leadership skills, and his dream of uniting the ninja world, he would make a great 6th Hokage.
A group of corrupt politicians within the village itself could be the main antagonists. They might be secretly plotting to undermine Naruto's authority as the 5th Hokage in order to gain more power for themselves. They could be making deals with other villages or ninja groups that are not in the best interest of Konoha, and Naruto has to expose and stop their schemes.
Sasuke could also be a possibility for the 6th Hokage in the fanfic. He has grown stronger over the years and his unique perspective on the ninja world could bring new ideas to the leadership of the Hidden Leaf. He might start off as a controversial choice but prove himself through his actions in protecting the village and making tough decisions.
Obviously, the 5th Hokage herself. Then there would probably be Naruto, as he is a central character in the Naruto universe. Sakura might also be there, as she is one of Naruto's closest friends. And Kakashi could make an appearance, given his importance in the story. Shikamaru, with his intelligence, could also be involved, perhaps as an advisor to the 5th Hokage.
Obviously, Naruto himself is central. His family like Hinata and Boruto would be very likely to be involved. Sasuke is also a key character as Naruto's friend and ally. Kakashi, being Naruto's former teacher, could also play a role. Shikamaru, as Naruto's advisor, would be important in any political or strategic situations. And then there are the other members of the Konoha 11, like Sakura who could be involved in medical support or combat situations if needed.
Under Naruto as the 5th Hokage in fanfiction, the village would experience a cultural shift. Since Naruto values all kinds of people, the village would be more open to different ideas and ways of life. New forms of ninja techniques might be developed as he encourages everyone to explore their potential. Also, the village's defenses would be strengthened not just by physical means but also by the strong bonds between the villagers, which Naruto would foster.
In fanfiction, Naruto's rule as the 5th Hokage might be full of positive changes. He would probably focus on improving relationships between the different ninja clans in the village. He'd also likely invest a lot in training the new generation of ninjas, using his own experiences to teach them about perseverance and the importance of friendship.
