In many Naruto fanfictions where Naruto meets Kushina and Minato, it often creates a very emotional scenario. Naruto finally gets to meet his parents who he has only heard about. It could be a heart - warming reunion where they share stories, hugs, and Minato and Kushina get to see how far Naruto has come.
One possibility is that Naruto has an out - of - body experience and is able to communicate with his parents in a spiritual realm. They could give him advice on how to deal with his enemies and his inner demons.
In such a fanfiction, Naruto would probably be overjoyed. He could finally have a proper conversation with his parents. Minato might share some of his jutsu secrets or stories about being Hokage. Kushina would surely embrace Naruto tightly and tell him how much she loves him. They could also have a family meal together, a simple yet precious moment that Naruto has always longed for.
On a more personal level, they could face internal guilt. As Naruto grows up and achieves great things on his own despite their neglect, Minato and Kushina may realize what they've missed out on. This realization could cause them a great deal of internal turmoil and regret for not being there for their son when he needed them.
A fanfiction could explore the backstories of these characters more deeply. For instance, how Mikoto came to be so proficient with her sharingan, and how her friendship with Minato and Kushina developed over time. This could add a lot of depth to the existing Naruto lore.
There's a fanfic called 'Minato's Return'. In this story, Minato somehow returns and gets to see Naruto's growth. It's really interesting to see how he interacts with Kushina, who is also there in the story, and how they both guide Naruto in new ways. The descriptions of their family bond are heartwarming.
It could change the power balance in the ninja world. Other villages might see Konoha as a much greater threat with Minato and Kushina back. On the other hand, it could also lead to more cooperation as they might be seen as a symbol of hope. Emotionally, for Naruto, he would be able to learn more about his family, his heritage, and maybe even get some long - awaited parental guidance which would further develop his character.
On a personal level, for Naruto, it would mean having his parents around. He could finally experience a real family life. Kushina could teach him more about the Uzumaki clan's techniques and traditions. Minato could train Naruto further in his unique jutsu. Emotionally, it would be a great comfort for Naruto and many of his friends who knew about his longing for his parents.
Minato would probably be very proud. He might notice Naruto's use of his own jutsu and be impressed by how Naruto has developed his skills. Kushina would be more emotional, maybe crying at the sight of Naruto growing up so well.
At first, Naruto and Kushina might start to distance themselves from Minato. They could avoid him and not talk to him as much. As time goes on, the hatred might grow deeper. Naruto could start to oppose Minato in public or in important village matters. Kushina might also try to influence others in the village against Minato.
