It could mean that the council in the Naruto universe is asking for fan - made fictional stories. Maybe they want to see different interpretations of the Naruto world from the fans.
In this kind of fanfic, Naruto might respond with defiance. He has always been a character who follows his own path. So, he could simply ignore the council's demands and focus on his own training regime to grow stronger. For example, he might continue his intense physical and chakra training with Jiraiya, believing that his way of getting stronger is more important than following the council's old - fashioned ideas.
In this fanfiction, the council's demand for Naruto's power might be the starting point for a whole new adventure. Naruto could be forced to go on the run to protect his power. Along the way, he might discover new aspects of his power or even meet new allies who help him understand the importance of his power and why the council wants it. Maybe he'll also find out that there are some dark secrets behind the council's demand, which could lead to a major showdown between him and the council in the end.
If the council makes such a demand in fanfiction, it might be a way to bring the two rivals closer. Naruto, being the more open - minded one, could teach Sasuke about the value of friendship and the power that comes from believing in others. Sasuke, on the other hand, might learn new combat skills from Naruto that could be crucial in future battles.
Naruto would probably be excited at first. He has always wanted to help Sasuke and this would be a great opportunity for him to do so. He'd be eager to share his skills and knowledge.
He may also face opposition from some council members who are afraid of his growing power. They could try to set him up or sabotage his efforts to grow stronger. Naruto would then have to be cautious and find ways to outwit them while still focusing on his growth.
Naruto could also be angry. He has always been a bit hot - headed. He might think that Kakashi doesn't trust him enough with the sword or that Kakashi is trying to undermine his progress as a ninja. So, he would likely challenge Kakashi, either verbally or by showing his determination not to give up the sword without a good reason.
He might use his influence as a hero. Naruto has a lot of friends and supporters in the village. By getting them to see his point of view about the council's inefficiencies or wrongdoings, he could start a movement to oust the council. For example, he could talk to his old friends like Shikamaru, who is intelligent and might be able to come up with a strategic plan.
One possible reason could be that the council often restricts Naruto's actions. They might see him as a potential threat or a wild card due to his Nine - Tails power. So, Naruto, being a free - spirited person, would naturally hate being controlled by them.
Naruto could also show his hatred through his actions. Maybe he refuses to cooperate with any mission or task that is directly related to the council's orders. He would rather do things his own way or follow the orders of someone he trusts more, like Kakashi or Iruka.
