A simple plot could be that they are invited to join as a sign of a new era of cooperation. Naruto and Sasuke accept and immediately start to work on improving relations. They hold joint training sessions for the ninjas of both villages, which helps in building trust and camaraderie.
One possibility could be that Naruto and Sasuke, with their newfound understanding and power, decide to bridge the gap between Konoha and Suna. They might start by sharing their unique skills and knowledge. For example, Naruto could teach Suna ninjas about his shadow clone jutsu, while Sasuke could offer insights on advanced chakra control. This would lead to a stronger alliance between the two villages, with the two heroes becoming symbols of unity.
One reason could be a special mission. For example, there might be a threat that only Naruto can help with in Suna. Maybe there's a new type of enemy that has some connection to Suna's unique chakra sources and Naruto's abilities are needed to figure it out.
In the long run, the relationship could be mended if Naruto is able to show that his move to Suna has been beneficial not only to him but also to both villages. His friends might start to see his actions in a new light. They could collaborate on certain projects or missions that involve both Konoha and Suna. However, there would always be a sense of loss and change in their relationship. Naruto's departure would be a significant turning point, and they would have to re - evaluate their friendship in the context of the new situation where Naruto is now part of Suna.
It's not clearly stated in the original Naruto series that Konoha as a whole watches Naruto vs Sasuke fanfiction. Fanfiction is a creation of the fans outside the official story. However, it would be an interesting concept to think about. Some characters might be amused or even inspired if they were to read such fan - created stories, but there's no in - canon evidence for it.
This type of fanfiction concept is really out of the ordinary. Naruto's character is built on his values of friendship, loyalty, and his dream of becoming Hokage. Killing Sasuke would mean betraying all of that. However, in a fanfiction, the author might be exploring the 'what - if' scenario. For example, what if Sasuke's actions against Konoha were so heinous that Naruto felt he had no choice? But still, it's a far - fetched and very different view from the original Naruto we know.
He could encounter new types of ninja beasts. For instance, he might come across a giant sand - dwelling creature that he has to fight or befriend. This could lead to a whole new set of skills or knowledge about the world outside Konoha.
Naruto might leave Konoha for Suna because he sees Suna as a place where he can make a real change on a larger scale. Konoha is a well - established village with its own ways, and it might be difficult for Naruto to implement his ideas fully. In Suna, which may be in a more desperate or rebuilding state, he could have more influence. Additionally, if there are personal vendettas against him in Konoha that he can't resolve, he may choose to flee to Suna to escape the hostility and find a new purpose.
Naruto could use his own growth and strength as an example. He shows Sasuke that he has become stronger not just in power but also in his understanding of the ninja world. He tells Sasuke that together they can change Konoha for the better, that Konoha has changed since he left and is now a place where he can be accepted and contribute. He might also share his own experiences of loneliness and how having Sasuke back would complete him in a way.
One reason could be that he feels betrayed in Konoha. Maybe some secrets were uncovered about the village's past actions towards him or his family that made him lose faith. So, he decides to start anew in Kiri where he hopes to find a different kind of acceptance.
