If Kitsune Naruto was in Highschool DxD fanfiction, it could change the power balance. Naruto is already a very powerful character from his own series. His Kitsune powers, like the nine - tailed fox's chakra, are extremely potent. In Highschool DxD, this could make him a major player. He might not be as interested in the whole devil - angel - fallen angel conflict as the original characters, but his presence would force all the parties to take notice. His unique abilities would also mean that he could teach the other characters new ways of fighting or using their powers, which would have a big impact on the overall story.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Some fanfics might focus on Issei's adventures with Kitsune elements added in, such as new powers or relationships. Just search for 'Highschool DxD Issei Kitsune' on those platforms and you'll find a variety to choose from.
Well, one way the storyline could develop is that the Naruto Godlike Kitsune would bring in his ninja skills to the world of Highschool DxD. He could use his transformation abilities like the Kitsune form to deceive enemies or charm the characters in the DxD world. Maybe he'd form an alliance with some of the main characters to fight against common foes, like the devils or fallen angels who might see his power as a threat.
He could play the role of a mentor. Since he has godlike powers, he could teach the characters in Highschool DxD new ways of fighting or using their powers more effectively. For instance, he could show the devils how to better use their magic in a more stealthy and efficient way, just like how ninjas use their skills in Naruto.
There could be some really interesting interactions. For instance, Naruto might form an unlikely friendship with Issei. Issei is always looking to become stronger and Naruto, with his vast experience and power, could be a great mentor to him. Or he could have a rivalry with some of the more prideful devils or angels who see his Kitsune powers as a threat. Naruto's friendly and outgoing nature could also lead him to befriend some of the female characters, which might cause some jealousy among the male characters in the Highschool DxD world.
You could also have a Kitsune OC who is a master of disguise. She uses her Kitsune abilities to transform into different students or teachers at the school to gather information. Maybe she's on a secret mission to find out about the hidden powers within the school. This would add an element of mystery to the fanfiction.
FanFiction.net is a very popular site for fanfiction. It has a wide range of stories, including those related to Highschool DxD Issei Kitsune. You can use the search bar on the site and type in the relevant keywords. Archive of Our Own is another excellent option. It has a well - organized tagging system, which makes it easier to find the exact type of fanfiction you're looking for. Additionally, some anime - related forums may also have threads dedicated to sharing fanfictions.
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.
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.
The female characters from Highschool DxD, like Rias, would be intrigued by the unique personalities of the Naruto characters. Rias might see potential in some of them to join her peerage. And the Naruto girls, like Sakura, would be a bit shocked at first by the more revealing outfits and flirty nature of some of the Highschool DxD characters. But over time, they would bond over things like protecting their friends and the school. The Naruto boys would respect the power of the Highschool DxD devils and might even try to incorporate some of their fighting strategies into their own ninja combat styles.
