It could also be due to the overall tone and plot of the fanfiction. If the fanfiction has a dark or negative theme and Yasaka is a part of that in a way that makes Naruto seem to 'hate' her, it might be because the writer wants to create some sort of conflict. However, this may not align with the original essence of Naruto's character, who usually tries to understand and befriend rather than hate without a good reason.
Some fans might be disappointed. Those who love Naruto's positive and inclusive nature may not like to see him hating on another character, especially if they are fans of both Naruto and Yasaka in their original portrayals. It can create a divide among fans who either support this new take or oppose it.
In fanfiction, Naruto could be portrayed in various ways. He might be a character with new relationships and roles. Without reading the specific 'naruto father of yasaka fanfiction', it's hard to say exactly. But generally, he could be a father figure to Yasaka, which would likely involve a lot of character development and new storylines related to protecting, guiding, or having a special bond with Yasaka.
One possible fanfiction could involve a crossover where the characters from Highschool DxD and Naruto meet in a unique world. Yasaka, being a powerful figure in the Highschool DxD universe, might interact with Naruto characters. For example, she could form an alliance with Naruto to fight against a common enemy that somehow threatens both of their worlds. Maybe a group of rogue ninjas from Naruto's world team up with some rogue devils from Highschool DxD.
One popular 'Naruto and Yasaka married' fanfiction might be 'Naruto: The Kitsune's Husband'. It explores their relationship in a world where Naruto somehow ends up in the Youkai realm and marries Yasaka. The story has some interesting twists on Naruto's powers and how he adapts to the new culture.
A common theme is power. Since both Naruto and Yasaka are powerful in their own rights, many fanfictions explore how their powers interact and combine. Another theme is friendship. They often form a strong bond in these stories.
Lemon could be a magical fruit in the fanfiction that gives special abilities to those who consume it. Naruto, Kuroka, and Yasaka could be on a quest to find more of these Lemons to gain power for their respective goals.
One challenge could be cultural differences. Naruto is from the ninja world with its own set of values and traditions, while Yasaka is from the youkai world. Another might be the acceptance of their relationship by their respective communities. The ninja might be suspicious of a youkai, and the youkai might not fully trust a human like Naruto at first.
In a fanfiction where Naruto marries Yasaka, it could lead to a very interesting cultural blend. Naruto's ninja world values and skills could mix with Yasaka's world. Maybe they would create a new form of combat training that combines ninja techniques and whatever powers Yasaka has. Their relationship might also have an impact on the political relations between the two fictional universes they come from, leading to new alliances and treaties.
