It could strengthen his bond with his family. Since Kushina was his mother, having her memories might make him understand her better and also feel closer to his father, Minato. He would know the love and sacrifices they made for him, which could make him more protective of the family name and legacy.
His relationship with the village could also be impacted. Kushina was a part of the Hidden Leaf. Her memories could give Naruto a deeper sense of the village's history and its people. He might be able to make decisions that are more in line with the long - term well - being of the village, as he has a more comprehensive view of what the village means, based on his mother's memories.
His relationships with his friends like Sasuke and Sakura would be deeply affected. They might feel like they've lost a part of Naruto. Sasuke, for instance, might initially be frustrated as he's used to Naruto's determination. Now, with his memories gone, Naruto might seem like a different person to Sasuke.
Well, it could lead to a whole new direction in the story. Maybe Naruto's control over Kushina gives him an edge in battles. For example, if Kushina has some special abilities or knowledge, Naruto could use that to outwit their enemies. It might also change the relationships in the Naruto universe. Other characters might react differently to Naruto having this kind of control, and it could create new alliances or rivalries.
Naruto might feel abandoned at first. Since Kushina is his mother, her leaving could make him feel lonely and question why she has to go. He may become more withdrawn.
It could add to the popularity of certain types of fanfiction. If Kushina is seen as being obsessed with it, more fans might be interested in exploring the fanfictions she might be interested in. For example, if there are fanfictions that focus on Kushina's relationship with Naruto in new ways, those might gain more attention.
The relationship dynamics in Konoha would change significantly. Kushina was friends with many important people in the village. Her presence would mean different political and social interactions. For example, her influence might change how the village treats Jinchuriki in general. Instead of seeing them as just weapons, they might be seen more as valuable members of the village due to Kushina's example.
Perhaps Naruto uses Kushina's memories to better understand the political landscape of the village in the past. This knowledge could help him to navigate current political issues in the village more effectively. He could use the wisdom from her memories to make changes or prevent past mistakes from repeating, which would be a very engaging plot development.
It can strengthen Naruto's relationship with his family on a spiritual level. Even though they are sealed within him, he might feel a closer bond to his parents. This could make him more confident in his identity as the son of Minato and Kushina.
Well, it could have a huge impact. If Kushina hurts Naruto in the fanfiction, it might make Naruto more distrustful. He could become more withdrawn and have to work harder to build relationships later on.
Kushina's training in the fanfiction might also impact Naruto's mental state. Knowing that his mother is there to train him gives him more confidence. He feels more connected to his family and his Uzumaki heritage. This new - found confidence reflects in his battles, where he is more fearless and decisive.
Kushina would be extremely worried. She would rush to Naruto's side immediately and start using her medical knowledge or any available resources to help him get better.
