In Naruto fanfiction, family neglect can be shown in various ways. For example, Naruto's own upbringing was filled with neglect as he was shunned by the villagers. Fanfictions might expand on this by having his family, if they were alive, also be cold or distant. It could be that his parents, if alive, were too caught up in their shinobi duties to give him proper attention.
The concept can be portrayed through emotional distance. Naruto might not understand Yagura's cultural background or the significance of certain things to him. This lack of understanding leads to neglect. For example, Yagura has his own history and traditions as the Mizukage, and if Naruto doesn't respect or take into account these aspects, it can create a sense of neglect in their relationship in the fanfiction.
He may also seek solace in his friends. Since his family is neglecting him, Naruto would likely turn to his friends like Sasuke and Sakura. They become his new 'family' in a sense, providing the support and love he doesn't get at home. He shares his feelings with them and they encourage him to keep going, which helps him deal with the pain of neglect.
He might focus on his training more. By pouring all his energy into getting stronger, he can distract himself from the pain of family neglect. For example, he could spend long hours practicing new jutsu or improving his physical abilities.
For Naruto, the consequence of family neglect in fanfiction could be a deep - seated loneliness. He might have trust issues, always doubting if people really care about him or just using him. It can also make him more reckless in battle, as he doesn't have that family support system to hold him back from taking unnecessary risks.
It could also be due to some family curse or prophecy. In the Naruto universe, there are often strange powers and curses. Maybe there was a prophecy that said Naruto's family had to keep their distance from him to protect him from some greater evil. So, they chose to neglect him in order to keep him safe, even if it was a difficult choice.
In this kind of fanfic, Naruto might first feel a great deal of sadness. He could start to distance himself from his family. Maybe he focuses more on his training, pouring all his energy into becoming stronger so that he can prove himself without relying on his family's recognition.
Dark Naruto might become more rebellious. He could start to distance himself further from his family and focus on building his own power. Maybe he'll find allies outside of his family who understand and support him.
He might develop them through self - discovery. Maybe he stumbles upon some old scrolls or has a natural inclination towards it that he nurtures on his own.
The family neglect can make Naruto overly self - reliant. He has to take care of himself from a young age, so in the yaoi fanfiction context, he might be stubborn in relationships. He's used to doing things his own way and may not easily accept help or affection from his love interests. Also, he could be more distrustful. Since his own family let him down, he may find it hard to trust others fully, especially those he has romantic feelings for.
One possible reason could be jealousy. If Naruto has the rare Mokuton ability, his family might be jealous of his potential power and neglect him out of spite.
