In the fanfiction, perhaps Minato's dying wish is for Naruto to bring peace between the Uzumaki and Senju clans. Kushina could play a role in guiding Naruto to understand the significance of this task. She might share stories of their clan's past and how important it is to heal the old wounds. Naruto, full of determination, then sets out on a journey to fulfill his father's last request.
One idea could be that as Minato is dying, he passes on his special jutsu knowledge to Naruto in a final moment of father - son connection. Kushina, on the other hand, tries to comfort Naruto while also mourning Minato.
A fanfiction could center around a family training session. Minato trains Naruto in advanced ninjutsu techniques while Kushina teaches him about the Uzumaki clan's secrets. This would not only strengthen their family bond but also make Naruto an even more powerful ninja.
One possible reason could be a misunderstanding. Maybe Minato thought Kushina had done something to endanger Naruto when in fact she hadn't. In the heat of the moment, he lost his temper and slapped her.
One idea could be that Naruto grows up with his parents in a world where the Nine - Tailed Fox attack never fully happened. Minato and Kushina could train Naruto from a young age, passing on their unique jutsu and wisdom. Maybe Naruto would be less of an outcast and more of a confident shinobi early on.
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.
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.
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.
If Minato didn't die in the fanfiction, he could have been a great mentor to Naruto. He could have taught Naruto advanced ninjutsu much earlier, and Naruto might have become even more powerful at a younger age.
Most Naruto fanfiction tends to focus on positive aspects such as character development, exploring backstories more deeply, or creating new adventures. A plot about Kushina cheating in such a way is not in line with the values the series promotes. However, the Naruto fanfic world is vast, and there might be some out - there that try to be edgy or different, but it's not a common or popular theme.
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.
In the fanfiction, it could be that a powerful enemy uses a forbidden jutsu that merges Naruto's consciousness with that of a world where Minato is female and Kushina is still alive. Naruto has to adapt to this new reality and figure out how to work with them to break the jutsu. During this time, he discovers new aspects of his parents' personalities. Female Minato might be more nurturing yet still have the strategic mind of his father, and Kushina could be even more protective. They form a strong bond as they fight to return Naruto to his own world.
