If Naruto is forced to become a daimyo in the fanfiction, first of all, his physical appearance might change to fit the more regal role. His training as a ninja would be put to the test in different ways. Instead of fighting on the battlefield, he'd be in the middle of political battles. He would also have to deal with the expectations of the people under his rule. His old enemies might see this as an opportunity to take advantage of his new situation, while his friends would support him in trying to make the best of this strange new role.
Well, Naruto would probably face a lot of challenges. He's used to being a ninja, not a daimyo. He'd have to adapt to a new lifestyle. He might try to bring his ninja values to the daimyo role, like honesty and loyalty. But the existing power structures in the daimyo's world might oppose him. And he could end up changing the whole political landscape in the process.
It's possible that an outside force from another country is behind it. They want to weaken the Land of Fire by putting Naruto, a powerful and unpredictable element, in a position where he has to deal with political matters rather than ninja battles. They believe this will make the Land of Fire more vulnerable to their future attacks.
Well, it could be a really strange scenario. Maybe Naruto would be forced to adopt Daymo's way of thinking or fighting style. It might change his relationships with his friends in the village as they try to understand this new Naruto who is being forced into something so foreign.
In a fanfiction where Naruto is adopted by the Daimyo, Naruto would likely experience a significant shift in his social status. He would no longer be the lonely orphan in the village. Instead, he'd be part of the Daimyo's family. This could open up new opportunities for him. He might meet different kinds of people, including nobles and diplomats. His ninja skills could be put to use in different ways, perhaps in diplomatic negotiations or protecting the Daimyo's territory. His perspective on the world would change as he'd be exposed to the political and social workings of the Daimyo's court.
Well, he might become a kind of special agent for the Daimyo. He could be sent on important diplomatic missions to other lands. His strength and reputation would make other villages take the Fire Daimyo's requests more seriously.
One possible main plot twist could be that Naruto discovers that the people forcing him to become daimyo are actually being controlled by an old enemy. This enemy wants to use Naruto's new position to gain power in the hidden villages. So Naruto has to figure out how to break free from this forced situation while also dealing with the political chaos that starts to unfold as a result of his new status.
Well, Naruto might influence the Daimyo to make positive changes in the Land of Fire. For example, he could convince the Daimyo to invest more in the villages' infrastructure or education. Maybe Naruto would also share his stories of heroism with the Daimyo, which in turn could inspire the Daimyo to be more involved in the well - being of his people.
In this fanfiction, Naruto's character development would be quite complex. Initially, he'd be resistant to the idea of being a daimyo. But as time passes, he'd start to understand the importance of his new role. His impulsive nature might be toned down as he realizes the consequences of his actions have a much wider impact. He'd learn about leadership in a new way, not just leading a team of ninjas but an entire territory. His relationships with his friends would also change as they now have to interact with him in a different capacity. And he'd probably start to develop new skills related to governance and administration, which would be a big shift from his ninja skills.
If the Fire Daimyo finds out Naruto is alive in fanfiction, it depends on how the author wants to develop the story. Maybe the Daimyo will be overjoyed as Naruto is a great hero. He could hold a grand celebration in Naruto's honor. However, there could also be a darker side. Some of the Daimyo's advisers might see Naruto as a threat to their power. They might try to plot against Naruto, which would then lead to a whole new series of adventures for Naruto to face and overcome.
In this fanfiction, Naruto might gain more political influence. Since the Fire Daimyo is a very important figure in the Fire Country. Maybe Naruto will be given a special mission by the Daimyo to protect the country in a new way.
Well, in such a fanfiction, Naruto might bring his unique ninja skills to Fairy Tail. His shadow clone jutsu could be used in creative ways during battles in the Fairy Tail world. Maybe he'd form an interesting bond with Natsu, sharing their love for a good fight and loyalty to their friends.
