One possible reason could be that Naruto's newfound power and responsibilities as he got older made his family feel distant. Maybe they didn't know how to handle the fact that he was no longer the little boy they knew. Another reason might be that his family got caught up in their own affairs, like political or social matters within the village, and unknowingly neglected Naruto.
Well, it could be that Naruto's family had some internal issues. For example, if there were family secrets or past traumas that resurfaced. They might have been so preoccupied with dealing with these problems that Naruto was left on the sidelines. Also, perhaps Naruto's achievements made them jealous in a way, and instead of being proud, they distanced themselves, leading to the neglect.
In the context of fanfiction, the writer might be exploring the idea of Naruto's family being influenced by external forces. Maybe there was some sort of dark magic or curse that affected their perception of Naruto. Or it could be that the village itself had certain expectations of Naruto as he grew older, and his family, trying to conform to those expectations, ended up neglecting his emotional needs.
It could be that his sister has some special abilities or talents that the family or the village values more. For example, if she has a very rare and powerful bloodline limit, everyone's attention would be drawn to her. In a ninja world, power and potential are highly regarded, so Naruto might be overlooked because his sister seems to have more of that 'special something' at first glance.
One possible plotline could be Naruto's struggle with self - worth. Since his family neglects him, he might constantly doubt his value. He could start to seek validation from other sources like his friends or mentors in the ninja academy. For example, he may pour all his energy into training to prove that he's worthy despite his family's lack of attention.
Perhaps there are family secrets or misunderstandings. His family might have some hidden agenda or past issues related to Naruto's brother that make them focus more on him. It could also be that Naruto's brother is seen as more compliant with the family's traditions and expectations, while Naruto is more of a free - spirit, which causes the neglect.
One possible storyline could be Naruto exploring the village and finding a surrogate family among the outcasts. He might bond with them over shared experiences of being shunned. Another could be Naruto trying to prove his worth to his neglectful family by achieving great things in the ninja world, like becoming Hokage. Or perhaps he discovers a long - lost relative who actually cares for him and they go on a journey to make his family recognize his value.
Maybe there are secrets in the family. For example, his parents might be involved in some dangerous and secretive missions that require them to keep their distance from Naruto to protect him, but Naruto misinterprets it as neglect.
Maybe the brother is seen as more obedient and studious. In a ninja village, those traits are often highly valued. Naruto, on the other hand, is very boisterous and doesn't always follow the rules. So, in the fanfic, the family or those around them might give more attention to the brother. Also, it could be that there's some sort of prophecy or family legacy associated with the brother that overshadows Naruto, causing the neglect.
He might become withdrawn. Naruto, who was always so full of life and energy, could start to keep to himself more. He might stop seeking his family's approval and focus on his own path, whether it's through training or making new friends outside of the family.
Another plotline could involve Naruto leaving the village due to the neglect. He goes on a journey, becomes even more powerful, and then the family realizes they need him when a new enemy targets the village. But Naruto has to decide whether to forgive them or not. It could explore themes of forgiveness and self - discovery.
In some fanfictions, it could be due to jealousy. Maybe other family members are jealous of Naruto's potential or some special ability related to EMS (whatever it is). So they choose to neglect him.
Well, perhaps in this fanfic, Naruto's family has a different set of values compared to Naruto. His determination to become Hokage and his unwavering belief in himself might be seen as over - ambitious or self - centered by his family. His family, who might prefer a more low - key and traditional lifestyle, could start to hate him because they think he is disrupting the family's harmony and going against their long - established ways.
