One possible reason could be a long - held misunderstanding. Maybe Naruto discovers some family secrets that he misinterprets as betrayal or neglect. For example, if he finds out that his family had made some sort of pact that he disagrees with, it could lead to his rejection.
Well, one possibility is that Naruto, in his godlike state, might feel that his family's expectations or their way of life is holding him back from achieving some greater good. Maybe he has a different vision for the ninja world that his family doesn't understand or support, so he rejects them to pursue that vision on his own.
His family members themselves could potentially be antagonists in a sense. If Naruto is rejecting them, there could be some family members who try to stop him from leaving or try to change his mind forcefully. They might see his rejection as a threat to the family's reputation or unity.
One possible reason could be a sense of betrayal. Maybe he discovers some long - hidden secrets about his family that make him feel they are not who he thought they were. For example, if he found out his parents had some kind of deal with the village elders that he disagreed with.
In the long run, if there is a resolution, Naruto's character development could show great growth. He might learn to forgive or understand his family's situation, and through this journey, he could become more empathetic and a better leader. He will have gone through a tough emotional experience and come out stronger, having a more nuanced view of family relationships.
One possible reason could be the burden that comes with his heritage. Naruto's heritage is filled with great power and responsibility. Maybe he feels that he can't live up to the expectations of his clan or predecessors, so he rejects it.
In this fanfiction, Naruto could reject his clan because of the dark secrets or past actions of the clan. He is a character who values justice and friendship. If the clan has a history of wrongdoings that he discovers, he may not want to be associated with it. Also, Naruto has his own dreams and goals that might not fit within the framework of the clan. He has always been a bit of a rebel, and rejecting the clan could be his way of standing up for what he believes in.
It could be that in this fanfiction, there are some external influences like an enemy who has manipulated Naruto's mind. The enemy might have planted false memories or ideas in Naruto's head, making him believe that his parents are not who he thought they were, leading to his rejection.
It would also impact his relationship with his village. The village has always seen Naruto as a part of their heritage in a way, especially considering his connection to the Fourth Hokage. If he rejects his heritage, some villagers might feel betrayed or confused.
His relationship with Sasuke could be affected in a big way. Sasuke is very much tied to his clan, and Naruto's rejection might make Sasuke view him differently. It could either create a rift between them or make Sasuke question his own loyalty to his clan. As for his friends like Sakura, she might be initially shocked but then try to understand Naruto's perspective.
