There's a good chance that the main character would be the one who is seen as the real fifth Hokage in this fanfic. However, other important characters from the Naruto series would probably also be involved. For instance, Sakura could be there, as she is a key figure in the original story. The story might also introduce new characters who are either allies or opponents of the character aiming to be the fifth Hokage. These new characters could bring in new plot twists and storylines related to the power struggle for the position of the fifth Hokage.
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.
