Another reason could be related to power. He might discover a new and dark source of power that Konoha would not tolerate. Feeling that he has no choice but to embrace this power to achieve his goals, he leaves. He could be on a quest for greater strength and believes that Konoha's rules and values would hold him back from reaching his full potential.
One possible reason could be that he feels ostracized. In the Naruto series, Naruto was often treated as an outcast in Konoha in his early days. If he turns dark, this feeling might be magnified to the point where he decides to leave. He may think that Konoha doesn't really accept him and that he can find a better place or a new purpose elsewhere.
Another reason could be related to his friends. If something bad were to happen to his closest friends in Konoha, and he felt that the village was at fault or unable to protect them, Naruto might leave in grief and anger. He values his friends deeply, and their well - being is one of his top priorities.
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 plot reason could be discrimination. In the Naruto world, there are often biases against those with different abilities or appearances. If Fem Naruto is constantly facing unfair treatment in Konoha due to her being a female version of Naruto, she might decide to leave. For example, she may not be given the same opportunities as male ninjas in training or missions. Another reason could be a search for identity. Maybe she feels that she can't truly be herself in Konoha and needs to go on a journey to discover who she really is away from the village that has so many expectations of her.
He could leave because of a broken heart over a lost love. If Naruto had strong feelings for someone in Konoha, like Sakura, and she chose someone else or rejected him in a cruel way, it might be too much for him to bear. So he decides to leave the place full of memories related to that person.
Another reason could be related to a secret mission. In some fanfictions, Naruto might be given a top - secret mission that requires him to leave Konoha undercover as an 'assassin'. This mission could be something that only he can do, perhaps related to protecting the village from a powerful hidden enemy. So, he has to leave and take on this dangerous role away from the prying eyes of the villagers.
One reason could be that he feels ostracized. Despite his efforts to protect Konoha, some villagers still look at him with suspicion because of the Nine - Tails inside him. He might just get tired of constantly having to prove himself and decide to leave in search of a place where he can be accepted for who he is.
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.
One possible reason could be a sense of betrayal. Maybe he felt abandoned or mistreated by Konoha in some way. For example, if he was shunned because of the power within him that others feared.
Perhaps he discovered some dark secrets about Konoha that made him lose faith in the village. For example, if he found out that the village leaders were involved in unethical or immoral activities that were against his values, it could make him hate Konoha. He might also feel betrayed if his so - called friends turned their backs on him for some reason.
In this fanfiction, Naruto might leave because of the political situation in Konoha. There could be factions that he doesn't agree with or that are causing unrest. Naruto, being someone who values peace and unity, might find it difficult to deal with the internal politics and decides to leave in order to find a more harmonious place or to figure out a solution away from the chaos.
