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.
The OC, as the Son of Sparda, could fit in by being a new and powerful entity. He might be initially seen as an outsider, but his powers would quickly draw attention. He could become involved in the power struggles between the different factions in Highschool DxD. For example, the devils might try to recruit him, while the angels might be wary of his presence. His unique abilities would also make him a valuable ally or a fearsome opponent. And in the high school setting, he could be a bit of an enigma to the other students, both human and supernatural.
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.
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 great fanfiction could be where the OC has a unique power that Akeno is initially intrigued by. For example, the OC might have the ability to control light in a different way than the devils in the Highschool DxD universe. This could lead to a series of adventures where Akeno and the OC team up to face various challenges. They could start off as just acquaintances but gradually develop a deeper bond as they fight side by side.
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.
One possible aspect could be the unique abilities that Eve might possess in her reincarnated form. In Highschool DxD fanfiction, new characters often bring fresh powers. For example, Eve could have a special power related to light or healing, which would make her a valuable asset to the group. This could also lead to interesting storylines where she has to learn to control her powers while also dealing with the typical Highschool DxD chaos of devils, angels, and fallen angels.
To write a Highschool DxD OC Angel fanfiction, start with a strong concept for your angel. Are they a high - ranking angel with a lot of power or a newbie just learning the ropes? Next, think about their relationships. Who will they be friends with? Enemies? You can also add some unique abilities to your OC, like the ability to heal any wound or the power to manipulate light in a special way. As you write, keep the tone and style of the original series in mind to make it feel like it belongs in the Highschool DxD world.
One great Highschool DxD OC Angel fanfiction is 'The Angel's Ascent'. It has an interesting plot where the OC angel has to navigate the complex world of the DxD universe while hiding her true powers. It's full of action and some great character development.
