The plot could also develop into a conflict with the village. Since Naruto is a key figure in the village, his rejection of his family might have political implications. The village elders might try to interfere and bring Naruto back to the 'right path' which could lead to a power struggle between Naruto and the village leadership.
In this fanfiction, the plot development might begin with Naruto being transported to Rias' world or vice versa. When Naruto rejects Rias, it causes a stir in the power balance of Rias' world. Her peers might be shocked or angry at Naruto's refusal. Meanwhile, Naruto is just trying to figure out how to get back to his own world. As the story unfolds, Rias might try to use her charm or power to change Naruto's mind, but he remains steadfast. This could lead to conflicts not only between Naruto and Rias but also between Naruto and the other characters in Rias' world who have an interest in the situation. Naruto will have to use his ninja skills and his strong will to navigate through this strange new world while constantly rejecting Rias' attempts to draw him in.
In this fanfiction scenario, the plot development could involve Naruto being part of his parents' missions earlier. Since he is trained by them, they might take him along to teach him real - world combat skills. This would expose Naruto to different threats and allies much sooner. Also, his relationships with other characters like Sasuke and Sakura could be different as he would have a different level of confidence and skill from the start.
He might become more independent. Without the protection of his parents, he has to fend for himself. So he could learn survival skills faster and become stronger in combat.
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.
The plot could start with Naruto growing up in a happy family. He'd learn about the village and ninja ways in a more positive environment. His first missions might be more successful as he has his parents' advice. As he grows, he might face threats to the village earlier, but with his family by his side, he'd be better equipped to handle them.
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.
His confidence would likely grow. Having the love and guidance of his parents would make him feel more secure.
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.
Naruto may become more self - reliant. Without the support of his parents, he has to figure things out on his own. He might grow up faster, learning to take care of himself at an early age. For example, he would have to learn how to cook, clean, and do other basic life tasks all by himself.
Naruto's development would be exponential. His fighting style would change as he'd incorporate his father's jutsu knowledge. His emotional intelligence would also increase because of his mother's memories of handling relationships. He'd be more in control of his emotions and actions, not just acting on impulse like before.
