After Kushina finds out Naruto is alive, it could bring about a change in the emotional tone of the fanfiction. The story could become more about healing and family bonds. There might be flashbacks to Kushina's relationship with Minato and how she wants to make up for lost time with Naruto. This could also introduce new sub - plots, like Kushina trying to protect Naruto from any further harm, or Naruto trying to prove himself to his mother. Their reunion could also inspire other characters in the story, leading to a more positive and united front against any threats.
One consequence could be a shift in the power dynamics. If Kushina is alive and now reunited with Naruto, they could form a powerful duo. This might make their enemies more cautious or even lead to new alliances being formed against them. Also, Naruto's morale would be greatly boosted, and he might become even more determined in his goals, which could speed up the overall plot development.
She might be overjoyed. After all, Naruto is her son. She could immediately rush to find him and embrace him tightly, tears of happiness streaming down her face.
One possible plot twist could be that Kushina's survival was part of a grand plan by an unknown entity. Maybe she was hidden away to protect Naruto from some greater threat that was yet to be revealed. Another aspect could be the emotional turmoil Naruto would go through. He'd be overjoyed, of course, but also confused and maybe a bit angry that he was made to believe she was dead all this time.
Well, one possibility is that Dark Naruto would be overjoyed. After all, Kushina is his mother. But at the same time, he could be very conflicted. His dark side might make him suspicious of her motives. He could test her in various ways to see if she's really who she says she is. And Kushina, on her part, would probably be heartbroken to see what her son has become.
One thing that could happen is that Dark Naruto would be filled with a mix of emotions. He could be angry at the village for hiding this from him, yet also feel a glimmer of hope. This discovery might make him question his loyalty to the forces that led him to become 'dark'. He might also feel a sense of longing for the family he thought he had lost.
Well, one possibility is that Naruto would be overjoyed. He has always longed for his mother's love. He might spend days just talking to her, sharing all his experiences, from his training with Jiraiya to his battles against the Akatsuki. Kushina would probably be extremely proud of him and would start teaching him some Uzumaki clan jutsus that were passed down in the family. And Naruto's relationship with the village would also change. He would no longer be the orphan that everyone pitied. Instead, he would be the son of a hero, which could bring a whole new dynamic to his standing in Konoha.
One possible reason could be a misunderstanding. Maybe some false information was spread about Kushina being a threat to the village, and Naruto, in his role as Hokage or a powerful figure, felt he had no choice but to banish her to protect the village. Another reason might be related to some sort of dark influence or curse that made Naruto act out of character and banish her.
In a Naruto alive with Kushina fanfiction, it could start with Kushina surviving the Nine - Tails attack. She then helps Naruto harness the power of the Nine - Tails in a more positive and controlled way. They might have a mother - son bond that is stronger than ever, and together they face new threats to the Hidden Leaf Village.
If Naruto found Kushina alive in a fanfiction, it might lessen his focus on Sasuke for a while. He'd be more centered on getting to know his mother. But in the long run, it could also make him stronger and more determined in his rivalry with Sasuke. With Kushina's support, Naruto would have a new source of motivation to prove himself not just to Sasuke, but also to his mother.
One possible plot could be that with Minato and Kushina alive, Naruto grows up in a complete family. They could train Naruto together, passing on their unique jutsu. Maybe Minato could finally fulfill his dream of bringing long - lasting peace to the Hidden Leaf with his family by his side. And Naruto would have a different kind of confidence and growth, not having to face the loneliness he did in the original story.
It could completely change the dynamics of the Naruto universe. Their presence might have prevented many tragedies and shaped Naruto's life differently.
