Well, Hinata could play a major role. Since she has feelings for Naruto, she may be deeply affected by his decision to abandon his child. She could be the one trying to convince Naruto to take the child back. Tsunade might also be important. As the former Hokage, she could be the one making decisions about the fate of the abandoned child in the village. And then there's Jiraiya. Even though he's dead in the original story, in fanfiction, his spirit or memories could influence Naruto's actions regarding the child.
Sakura could be a main character. She might be the one who discovers the abandoned child and tries to figure out what to do. Kakashi could also be involved. He has a history with Naruto and might be torn between loyalty to Naruto and doing what's right for the child. Sasuke could be another character. He might return to the village and get involved in the situation, either to help or because he has his own motives regarding Naruto's actions.
Sasuke could also be a main character. He might start off as an antagonist to the abandoned child, seeing them as a threat or simply not trusting them. But as the story progresses, their relationship could evolve. And then there could be Kakashi, who might be the one training the abandoned child in the ways of the ninja.
It could be a relative from his family who was behind the abandonment. Maybe they want to keep Naruto away from some family secret or power, and they will do anything to stop him from finding out the truth.
Perhaps it could be a new character created specifically for the fanfiction. A young ninja from a minor clan who showed extraordinary talent in a unique form of jutsu. But because their clan was small and not very influential, and the larger clans felt threatened by this new talent, they managed to get the village to abandon this prodigy.
Obviously, Naruto and his sister are the main characters. Naruto is the one with the godlike state, and his sister is the reason for his abandonment in this fanfiction.
In such fanfiction, one scenario could be that Naruto's child is abandoned due to his dangerous lifestyle as a ninja. His enemies might target his family, forcing him to send his child away for safety. Another possibility is that the child has some sort of special power that is not understood and feared by the village, leading to its abandonment. Or perhaps Naruto is in a difficult situation where he believes he can't take care of the child properly, like if he's constantly away on missions and has no support system at home.
In this fanfiction, Naruto is the central figure. Alongside him, we might expect to see characters like the Raikage from Kumo. Their interactions and differences in ideologies could be a major part of the story. There could also be some minor characters from both Konoha and Kumo who help to build the background and context of Naruto's decision to abandon Kumo, like the shopkeepers or other common shinobi who witness the events leading up to this big decision.
