Well, in such a fanfiction, Naruto might feel out of place in the Highschool DxD world. He could be heartbroken because he misses his friends from Konoha. Maybe he has a hard time adjusting to the different rules and powers in the new 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.
There could well be. Fanfiction writers often like to explore crossovers and unique concepts. However, not all fanfic writers might be interested in combining Naruto with 'Highschool DxD' in a certain way, so there are likely to be some that fit the 'Naruto not a devil highschool dxd fanfiction' idea. You might have to dig a bit through different fanfic archives to locate them.
In some Highschool DxD and Naruto crossover fanfictions, Naruto might be depicted as a god - like figure. This could be due to his extremely powerful abilities in the Naruto universe, such as his vast chakra reserves, multiple jutsu, and his status as a hero in his own world. Writers may take these aspects and amplify them in the Highschool DxD setting, where the power levels and the concept of beings with god - like powers already exist. So, it's possible for Naruto to be seen as a god in such fanfictions.
In such a fanfiction, it could be that Issei is bashed because he represents a different kind of hero compared to what Naruto stands for. Naruto is all about self - sacrifice and believing in others no matter what, while Issei is more about his own desires and power - seeking in a way. So when these two worlds collide in the fanfic, Issei might be made to look bad in comparison. Maybe the story has Naruto characters like Sasuke or Kakashi giving Issei a hard time because they don't approve of his behavior.

It would likely have Naruto dealing with his own set of challenges like fighting against the Akatsuki or protecting his village.

Also, the characters would be from the Naruto world, with their own personalities and abilities intact, without any 'Highschool DxD' - influenced changes.
In a Highschool DxD fanfiction, Naruto might appear if the author wants to create an interesting mash - up. It could be that Naruto is on a new mission and somehow ends up in the Highschool DxD world. For example, he could be chasing after a rogue ninja who has found a way to hide in that different realm. Or perhaps, the fanfiction writer just wants to see how Naruto's unique abilities, like his shadow clones or Rasengan, would interact with the magic and powers in the Highschool DxD setting.
One possible fanfiction could be about a crossover where Naruto characters end up in the Highschool DxD universe. Maybe Naruto himself could attend the high school and use his ninja skills in the unique situations there. He might form new friendships or rivalries with the characters from Highschool DxD.
