I'm not sure specifically without reading it, but there could be a hero who has a connection to the white dragon. Maybe a young adventurer who discovers the dragon and together they embark on a journey to bring justice.
There might be a villain in the fanfic as well. This character could be someone who opposes the white dragon's idea of justice. They could be a powerful sorcerer or a corrupt noble, trying to maintain their own power and status quo against the dragon's influence.
Given that we have no information about 'chasing the white dragon fanfic' other than its title, we can only make general assumptions about the main characters. It could be that the main character is an outcast who discovers the legend of the white dragon and decides to pursue it in order to prove themselves or find their place in the world. There could also be an antagonist who tries to stop the main character from getting to the white dragon, either out of jealousy or because they have their own plans for the dragon. Or perhaps there are multiple main characters, each with their own motives for chasing the white dragon, and their interactions and conflicts form the core of the story.
The fanfic might also introduce an interesting relationship between the white dragon and the characters. For example, some characters may be in awe of it, while others may be skeptical or even try to oppose it. This creates various story arcs and character developments within the fanfic.
Since I haven't read it, I can't say for sure. But I would expect the white dragon to be one of the main characters.

Well, Naruto is obviously one of the main characters. He brings his ninja skills, his determination, and his dream of becoming Hokage. The White Dragon Emperor or a character with its powers would also be a main character. They could be an ally or a rival to Naruto, depending on the plot of the fanfiction.
The main character is most likely the last dragon itself. But there could also be other important characters like a brave knight who tries to befriend the dragon, or a wizard who has some connection to the dragon's past.
In 'the dragon and the rose fanfic', aside from the dragon and the rose, there could be other characters too.
