One common pairing is Naruto and Sasuke. Their relationship in the original series is complex and filled with strong emotions. When Naruto leaves Konoha, it can be a turning point for their relationship to take a more romantic yaoi - like turn. Another pairing could be Naruto and Gaara. Gaara has always had a special connection with Naruto, and Naruto leaving Konoha might bring them closer together in a different way in fanfictions. There's also the pairing of Naruto and Kakashi. Kakashi is Naruto's teacher, and in some fanfictions, the departure from Konoha can lead to a more equal and romantic relationship between them.
One common theme is the exploration of unspoken feelings. In many of these fanfictions, Naruto's departure from Konoha becomes a catalyst for his relationship with another male character. For example, there could be a theme of longing and reunion. Another theme might be the struggle between duty and love. Naruto leaving Konoha means leaving behind his duties, and in the context of a yaoi relationship, he has to balance his newfound feelings with what he once held dear in the village. Also, themes of self - discovery are popular. Away from Konoha, Naruto can explore different aspects of himself, especially in relation to his sexuality and his emotional connection to the other male character.
Konoha would initially be in shock. Naruto is a hero to many in the village, and his sudden departure with Itachi, who was once considered a traitor, would cause a lot of unrest. The villagers might start to question the leadership of the village, wondering why Naruto left and if there was something they could have done to prevent it.
Another reason could be that he witnesses corruption or unfairness within the village leadership. If he sees that the system is rigged against certain groups, including himself or his friends, he could grow to hate Konoha and decide to leave.
One possible reason could be to seek stronger opponents outside of Konoha. Naruto might feel that he has outgrown the training opportunities in the village and wants to face greater challenges.
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.
It could lead to political unrest in Konoha. There might be those who blame the village leadership for Naruto's departure. This could lead to power struggles as different factions try to take control and change the way the village is run. Some might demand more transparency and better treatment of their shinobi to prevent such a thing from happening again.
Konoha's power structure could be affected. Naruto is one of the strongest shinobi in the village. Without him, the village might be more vulnerable to attacks from other villages or threats. They would need to quickly find ways to fill the gap in their defenses.
Sasuke might be more understanding. Given his own experiences of leaving Konoha, he could respect Naruto's decision. However, he might also secretly plan to keep an eye on Naruto from afar to make sure he is safe.
It could create a sense of unease and fear. Naruto is a very powerful ninja, and if he turns dark and leaves, the villagers would be worried about him coming back as an enemy. It might also lead to a decrease in morale among the ninjas who once considered Naruto a friend or ally.
