Maybe out of curiosity. They want to see how the fans view Kakashi, who was an important part of their lives. Kakashi was Minato's student and Kushina knew him well too. So they are interested in the different perspectives presented in the fanfiction.
They could read it to pass the time. In the afterlife or during their downtime, fanfiction about Kakashi could be an interesting and light - hearted read. It would give them a chance to see the more creative and often out - of - the - box ideas that fans have about Kakashi's character, his abilities, and his relationships.
They might be quite surprised. Minato might be proud to see how much Kakashi has grown in the fanfiction and how he is still upholding the values Minato instilled in him. Kushina could be amused at the creative interpretations of Kakashi's character. Maybe she would also feel a bit of motherly pride seeing how Kakashi has become an important figure in the village in these fictional stories.
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.
They might be quite surprised. Minato could be amused to see different interpretations of his heroic deeds. Kushina might be a bit shocked at some of the wild ideas about their family or Naruto. For example, she might not expect some of the out - of - character scenarios written in the fanfiction.
Well, in such a fanfiction scenario, Minato and Kushina reading the future would be a game - changer. They may use the knowledge to prevent the Nine - Tails attack on the village. They could also influence Naruto's upbringing in a more direct way. They might see the rise of new enemies and start training the next generation earlier to combat those threats. This would completely rewrite the Naruto story in many ways.
Their relationship might become stronger. Knowing the future, they would rely on each other more to face the challenges they see ahead. For example, they might work together to ensure Naruto's safety and well - being in a more coordinated way.
One possible reason could be a miscommunication in the fanfiction. Maybe some secrets were kept from Naruto about his parents that made him feel betrayed when he found out, thus leading to hatred.
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.
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.
One reason could be Naruto's journey. Naruto has to face so many challenges and grow from a lonely outcast to a hero. Minato might be more drawn to this growth and transformation, which is a big part of Naruto's story in fanfics.
In Naruto, the story is built on themes of family, love, and sacrifice. Minato and Kushina are important figures in Naruto's family tree. Minato was a great Hokage and Kushina was a strong - willed woman. Their love for Naruto is a fundamental part of the story's emotional core. So in fanfiction, it's hard to imagine a deviation from this where they would abuse Naruto. Most fanfiction writers prefer to stay true to the spirit of the original story, which is full of positive family values.
