I'm not entirely sure specifically as there could be many different takes in such a fanfiction. But generally, it might be about Naruto being banished to the west and could involve his adventures in that new, unfamiliar region. Maybe he has to face new enemies, make new allies, and deal with the unique cultures and challenges of the western - like area in the Naruto universe.
In the 'naruto banished west fanfiction', Naruto is the main focus. But it's likely there are other characters too. For example, the leader of the western region's ninja group could be a major character. He or she might initially be wary of Naruto but as the story progresses, they see Naruto's good side. There could also be Naruto's friends from the Leaf Village who try to find a way to bring him back, and their actions could be shown in parallel to Naruto's adventures in the west.
Well, without having read it, it could involve Naruto being sent away from his home, perhaps Konoha, and then rising to power in the west. Maybe he has to face new enemies, form new alliances, and deal with the politics and power struggles in that region. It could also explore how his ninja skills are adapted to this new situation and how his relationships with other characters change.
Naruto is surely a main character. There could be new characters created specifically for this fanfic as well. For example, local leaders or warriors in the west that Naruto has to deal with. Maybe there's a character who helps him when he first arrives in the west and becomes his right - hand person. And of course, we can't rule out the possibility of some of Naruto's old enemies showing up in this new setting to cause trouble for him.
Naruto might also initially feel a sense of abandonment. However, his kind - hearted nature could lead him to try and see the good in the situation. He could start to explore the world outside, learning about different cultures and ninja techniques. He may use this experience to become more empathetic towards others who have also faced hardships, and in the long run, this banishment could be a turning point in his life to become an even greater ninja.
At first, Naruto is probably shocked and confused. He might not understand why the village would take such a harsh step just for hurting Sasuke. He may feel betrayed, especially if he thought he had friends and allies in the village.
A possible plot for this type of fanfiction could involve the banished ninja having a secret mission that the village doesn't want to be associated with. So, they banish the ninja to make it seem like they have no part in it. The ninja then has to complete the mission while also dealing with the stigma of being banished.
Well, in a fanfiction like this, it could explore Naruto's sage mode abilities in a new context while he's with Yugito who has also been banished. Maybe they form an alliance to fight against the forces that banished them. They could discover new powers together and change the shinobi world's view of them.
In a 'Naruto and Anko Banished' fanfiction, the story could start with a false accusation against them. This would lead to their banishment. Once exiled, they could encounter new enemies and allies. For example, they might meet a group of outcasts who teach them unique jutsu. This would add new elements to their fighting styles and also change their perspective on the ninja world.
