There probably is. A lot of fanfiction platforms are filled with creative crossovers. Given the popularity of Naruto and High School DxD, some fans might be intrigued by the idea of Naruto being in the Dragon DxD universe. They could explore how Naruto's abilities would interact with the unique magic and supernatural elements in the Dragon DxD world, like how his ninja skills would fare against the devils and angels in that setting.
One idea could be that Naruto is somehow transported to the world of Highschool DxD. He could use his ninja skills and chakra in the new world, maybe even teach some of the characters there a thing or two about combat. For example, he could show Issei how to better control his power using chakra control techniques.
Yes, there might be such fanfictions out there. Fanfiction writers often create crossovers where they put characters from different universes like Naruto and High School DxD together and come up with various scenarios, including ones where Naruto could potentially 'kill' a character from the DxD universe. However, the quality and nature of these fanfictions can vary greatly.
In a Naruto and High School DxD fanfiction, there could be a scenario where the protagonists of both stories meet in a neutral dimension. Issei from High School DxD might be intrigued by Naruto's ninja skills and determination. Naruto, in turn, could be curious about Issei's Sacred Gear. They could start training together, sharing their knowledge and skills, and ultimately have to face a common enemy that threatens both their worlds.
No. Fanfiction should focus on positive and respectful exploration of the Naruto universe. This kind of theme is inappropriate and goes against the general positive and family - friendly spirit of the Naruto franchise.
Acceptable themes could be new adventures for Naruto and his friends. For example, they could embark on a journey to a new land in the ninja world, facing unknown enemies and challenges. This would keep in line with the spirit of exploration in the original series.
The storylines can be combined by creating a common threat. Suppose an enemy emerges that is interested in both the power of the Bijuu and the power sources in Highschool DxD. This would force the characters from both universes to team up. Also, the cultural differences between the Naruto world and the Highschool DxD world can be explored. Naruto could introduce concepts like ninja clans and shinobi training to the DxD characters, while they could introduce him to the complex social hierarchies and supernatural politics in their world.
Definitely not. The Naruto fanfiction community, like most fanfiction communities, values creativity and positive content. The terms'monster dick' and 'lemon' in this context imply adult and inappropriate content, which goes against the norms of a healthy fanfiction environment. Popular Naruto fanfictions usually focus on things like character development, new story arcs within the Naruto world, or exploring different powers and abilities of the characters.
Since 'monster dick' and 'lemon' are inappropriate terms, if we just focus on Naruto fanfiction, it can be about various things. It could be about exploring different relationships between the characters in the Naruto world, like new friendships or rivalries. Some fanfictions might also focus on giving background stories to minor characters that were not fully explored in the original anime or manga.
I'm not aware of any specific fanfiction with such a title. Fanfiction can cover a wide range of themes and stories. It's best to search on reliable fanfiction platforms like FanFiction.net or Archive of Our Own and use appropriate filters to find Naruto and Kushina - related stories.
