One idea could be a crossover where Naruto characters gain the powers of DxD characters. For example, Naruto could get the power of Issei's Boosted Gear and use it in combination with his own chakra powers. This would create some really cool battle scenes and new power - up scenarios.
One interesting crossover could be the combination of Naruto's ninja skills with the supernatural elements of High School DxD. For example, Naruto's shadow clone jutsu might be used in a unique way during a battle in the High School DxD universe. Maybe the clones could be used to distract the devils and angels while the main character executes a strategic move.
Sasuke might also be a top contender. His Sharingan and Rinnegan abilities could be enhanced by DxD magic. He could use his intelligence and combat skills along with newfound powers to become very powerful. For example, if he got a Sacred Gear that enhanced his genjutsu abilities, it would be nearly unbeatable.
For 'Star Hero DxD Fanfiction', 'The Celestial Dragon Emperor' is a must - read. It gives Issei a more celestial - themed power - up and his character development is really well - done. The story also has some great action scenes. Another one is 'The Starlight Devils'. This fanfic delves into the backstories of some of the devils in the DxD world and how they are connected to the stars. It's full of mystery and intrigue. And 'The Cosmic Struggle of DxD' shows how the DxD universe is affected by some cosmic forces and how the characters have to adapt to survive.
It could be Issei from High School DxD if he were to gain Naruto's abilities. His already formidable power with the Boosted Gear, combined with Naruto's jutsus like the Rasengan or even the ability to use chakra, would make him extremely powerful. He could use chakra to enhance his physical abilities even more during his devil forms.
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.

They could start training together, sharing their knowledge and skills, and ultimately have to face a common enemy that threatens both their worlds.
One common trope in 'Star Hero DxD Fanfiction' is the power - up. For example, Issei often gets some new and amazing powers related to the stars. Another is the alternate universe concept, where the DxD world has different rules or relationships.
