In the fanfiction, Naruto could leave Konoha because of a misunderstanding. Maybe he was wrongly accused of something and felt he had no choice but to leave to clear his name and find the truth. He might believe that staying in the village would only lead to more false accusations and restrictions on his actions.
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.
Another reason might be related to a prophecy or a personal quest. He could have received some kind of vision or message that led him to believe that his destiny lies outside of Konoha. He may need to leave in order to fulfill a greater purpose, such as protecting the ninja world from a new, unknown threat that can't be dealt with from within the village.
Maybe there are some dark secrets within Konoha that he discovers in the fanfic. These secrets could be related to the treatment of certain individuals or something more sinister about the village's leadership. Discovering such things could make Naruto decide to leave in order to distance himself from the corruption or unfairness.
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 for Naruto's safety. Maybe she has to go on a dangerous mission and believes Konoha is the safest place for him. Another reason might be that she is forced by some powerful enemies who threaten Naruto's life if she doesn't leave him in Konoha.
One possible reason could be a sense of disillusionment with the village. Maybe he feels unappreciated for all his efforts in protecting Konoha. Another reason might be that he is being framed for something bad in the village and decides to leave rather than face false accusations. Also, he could be lured by the promise of a greater adventure outside Konoha that is not directly related to money.
One possible reason could be that Naruto discovers some dark secrets about Konoha that shatter his idealized view of the village. Maybe he finds out that the village elders were involved in unethical practices, like using shinobi for immoral experiments. This would make him lose faith in Konoha and decide to leave.
Perhaps they are forced to leave due to false accusations or being framed for something they didn't do. This could create a situation where they feel they have no choice but to leave Konoha in order to clear their names and also protect the village from the real threats that might be lurking in the shadows.
Naruto might forgive Konoha because he realizes that holding a grudge won't solve anything. He has seen the destruction that hatred can cause, like during the Pain arc. So, he chooses to forgive in order to move forward and bring about positive change. Another reason could be his respect for the previous Hokages and their ideals for Konoha.
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 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.
