The theme of mentorship or friendship - turned - love is also seen. Maybe Kakashi starts as a mentor to Kushina, or they begin as friends and then feelings develop over time. Another aspect could be the exploration of their pasts. Both characters have had difficult experiences in their lives. Fanfictions might explore how these pasts shape their relationship, like how Kakashi's experiences with his team and Sensei could influence his relationship with Kushina, and how Kushina's upbringing as a Jinchuriki affects her feelings towards Kakashi.
One common theme is the exploration of their potential relationship. Since they are both characters in the Naruto universe, fanfictions often imagine how they could have interacted more if the story had been different. Another theme could be friendship, showing how they might support each other.
There are some. Some fanfictions might focus on their relationship in an alternate universe where they have different interactions compared to the original Naruto storyline. You could also try Naruto fanfiction forums where fans might recommend some good ones.
The combination of kakashi and kushina in fanfiction is interesting because they both have unique personalities. Kakashi is known for his cool and mysterious demeanor, while kushina is strong - willed and fiery. Their interactions can create a lot of drama and tension.
One possible scenario in such a fanfiction could be that Kakashi, while in ANBU, is assigned to protect Kushina during her pregnancy. He might have to deal with various threats against her and the unborn child. This could lead to some intense action scenes and also some character - development moments for Kakashi as he realizes the importance of protecting new life.
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.
There are many 'kakashi and kushina' fanfiction stories out there. Some might focus on their friendship during their days in Konoha. For example, there could be stories where they train together and share their ninja experiences. Another type could be about how they team up to face a powerful enemy that threatens the village.
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.
Maybe the main plot is about how Kakashi, in his ANBU role, has to balance his duties with his growing friendship or respect for Kushina. Her pregnancy could be a symbol of new hope in the village, but there are those who oppose it. Kakashi has to fight against these opposing forces, both physical and ideological, all while Kushina is going through the physical and emotional journey of pregnancy.
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.
