Since I haven't read it, I can't say for sure. But it might include Naruto and some of his friends as they are central to the Naruto universe. And of course, the character who is proposed as the'real' fifth Hokage.
I'm not sure specifically as I haven't read this particular fanfic. But generally, it might be about someone's idea of who should really be the fifth Hokage in the Naruto universe, perhaps presenting an alternative story arc or character development related to that.
Another aspect to explore in the fanfic is Naruto Senju's relationship with the other villages. Given his Senju heritage, there might be different expectations and tensions. He could work towards a more equal - footed relationship with other villages, instead of the traditional power dynamics. This would involve a lot of diplomatic meetings and negotiations, which could be full of drama and intrigue.
His friends like Sakura and Shikamaru would surely support him. Sakura, with her medical skills, could be an important part of his regime, providing healthcare for the ninjas. Shikamaru, being intelligent, could offer strategic advice. Also, the younger generation of ninjas who have been inspired by Naruto would be his strong supporters, as they believe in his leadership and the new direction he could take the village in.
One common theme is mentorship. Tsunade, as the Fifth Hokage, often takes on the role of mentoring Naruto. This can involve teaching him new jutsu or helping him grow as a shinobi.
There are fanfics that explore an alternate universe where the Fifth Hokage is in a relationship with Naruto's father, Minato. In such a story, Naruto's relationship with Tsunade becomes more complex as he discovers this past connection. It can be really interesting to see how the story unfolds with this new dynamic.
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.
In such a fanfic, Naruto might bring new policies to the village. For example, he could focus more on training the young ninjas in new and innovative ways. He might also strengthen the village's relationships with other villages by promoting more cultural exchanges and joint missions.
Well, Naruto becoming the fifth Hokage in the fanfic could mean a lot of changes in the village's defense strategy. He'd probably use his own unique experiences and skills. Maybe he'd set up a special unit that combines his Rasengan technique with other jutsus for more powerful defense. He's always been about innovation and unity, so he could also make the village more open to outsiders, which is different from traditional Hokage approaches.
