In the fanfiction, there could be a time - travel element. Kushina could travel to the future and see Naruto and Hinata together. She could then give her approval and advice to Hinata on how to keep Naruto happy. This would create a really interesting dynamic as Hinata would be getting advice from Naruto's mother, and it would also show how much Kushina cares about Naruto's future and the person he is with.
There could be a scenario where Kushina comes back to life somehow in the fanfiction. She might then play matchmaker between Naruto and Hinata, using her knowledge of Naruto to help Hinata understand him better. For example, she could share stories of Naruto's childhood that would make Hinata feel closer to him.
Another angle in this fanfiction could be the family dynamic. Since Kushina is Naruto's mother, the fanfiction could delve into how Hinata fits into this family unit. It might show how Hinata adapts to having Kushina in Naruto's life, or how they all support each other. There could be scenarios where they face challenges together and the unique ways each character contributes to overcoming those challenges.
In such a fanfiction, the relationship between Naruto and Kushina would be one of mother - son love and mutual respect. Kushina would be protective of Naruto and proud of the man he has become. Naruto would look up to Kushina and value her wisdom. With Hinata, Naruto's relationship would be that of a loving couple. Hinata would support Naruto in all his endeavors. When it comes to Kushina and Hinata, Kushina would likely see Hinata as a worthy partner for Naruto and Hinata would respect Kushina for being Naruto's mother and a strong kunoichi.
One possibility in such a fanfiction scenario is that Kushina's own chakra, which was already special as an Uzumaki, could have an impact on Naruto while he's sealed within her. It could either strengthen him in some ways or cause unforeseen consequences. Also, characters like Minato would have a different relationship with the situation. Instead of seeing Naruto as his son on the outside, he might be more focused on the presence of Naruto within Kushina, which could change how he approaches protecting his family and the village.
In this fanfiction, Naruto might finally get the motherly love he always craved. Kushina could share her unfulfilled dreams for Naruto, like seeing him grow up without the pain of being an orphan. They would probably have an emotional conversation about Naruto's father too.
In this fanfiction, their marriage could also lead to new ninja techniques being developed. Kushina was a powerful kunoichi, and Naruto has his own unique abilities. Combining their skills and knowledge, they could create something entirely new. This could have a significant impact on the Hidden Leaf Village, making it even stronger in the face of threats.
In fanfiction, this could be due to an alternate reality or a dark twist in the plot. Maybe Kushina was mind - controlled by some powerful enemy. It's a very strange and dark concept that goes against the normal Naruto storyline where Kushina is Naruto's mother and loves him dearly.
In some fanfictions, it might be due to an alternate timeline or reality. A change in the past could lead to Kushina having different beliefs or loyalties. It could also be related to a new power or curse that affects her judgment and causes her to see Naruto as an enemy. However, this is often a very dark and dramatic turn in fanfiction stories.
In this kind of fanfiction, Naruto might experience a very emotional moment. He could finally get to know his mother better. Kushina would probably embrace Naruto tightly, telling him how much she has missed him all these years. Maybe she would share some of the Uzumaki clan's secrets with him that no one else knew.
Well, Naruto might break a bond with Kushina in the fanfiction. Maybe he finds out some dark secret about her that makes him question their relationship.
In a fanfiction, if Minato were to slap Kushina, it would be a huge shock to the Naruto - Kushina relationship. It could potentially cause a rift between Naruto and his father Minato in Naruto's mind. Also, Kushina would likely be deeply hurt and angry, which might lead to her distancing herself from Minato. This event could also change the way Naruto views his family's past and his parents' relationship.
