One possible fanfic could be about an angel who gets trapped in the Naruto world and has to adapt to its ninja ways while still retaining some of the powers and characteristics from the DxD universe. For example, the angel might use its holy powers in a new way to fight against the akatsuki.
Yes, there could be such fanfictions out there. Fanfiction writers often like to cross over different popular franchises, and combining Naruto and Highschool DxD in this way is not unheard of. It allows for some really interesting character interactions and plot developments.
One possible fanfic could be about Naruto being transferred to the High School DxD universe and his encounter with the Juubi there. Maybe he has to team up with the characters from High School DxD to deal with the threat of the Juubi. For example, Naruto's unique abilities like the Rasengan and Shadow Clone Jutsu could be a great asset in battles within this new universe.
The plot could involve an angel accidentally falling into the Naruto universe. The angel then discovers that there are similarities between the chakra in Naruto's world and the magic in the DxD world. As the angel tries to find a way back home, it befriends Naruto and helps him in his journey to become Hokage, while also learning about the values of the Naruto world.
He could be a new type of threat or ally in the DxD world. Since Naruto has such powerful abilities, the fallen angels might see him as a potential weapon or a hindrance to their plans.
In 'naruto angel dxd fanfic', the characters from both Naruto and DxD get to interact in ways that are not possible in their original stories. For example, Naruto's sense of justice and his never - give - up attitude can have a big impact on the DxD characters. Also, the different power systems collide and sometimes merge, like Naruto's chakra with the magic in DxD. This can lead to really unique and unexpected plot twists. It's not just about putting the characters together, but also about how their worlds' concepts interact.
In this fanfic, Naruto's unique abilities like his shadow clones and Rasengan could be combined with the magic and powers in the DxD universe. For example, a fallen angel might be interested in Naruto's chakra and try to use it for their own purposes. Naruto, being the hero he is, would not let that happen and would start a conflict that could lead to an epic adventure.
In a Naruto - DxD fanfiction where Naruto is arrogant, perhaps he would look down on the Rating Game system in DxD. He'd think his combat experience in the ninja world is far superior. He could try to impose his own rules of combat, which would lead to many conflicts with the DxD characters who are used to their own ways.
One possible scenario could be Naruto with his Six Paths powers attending the highschool in the DxD world. He might use his powers in unique ways during the school's supernatural events. For example, his ability to sense chakra could be translated into sensing the different types of magical energies in the DxD school. He could also form interesting friendships or rivalries with the characters from DxD, like Issei. Maybe he'd teach some of them about chakra control in return for learning about their magical abilities.
He could fit in as a new type of supernatural being. Since he has god - like powers, he might be seen as a threat at first. But then, as the story progresses, he could form alliances. For example, he could team up with the devils against a common enemy. His abilities like instant teleportation (using techniques like Flying Thunder God) would be very useful in the battles in the Highschool DxD universe.
One interesting 'naruto angel dxd fanfic' could be 'Naruto in the DxD World'. In this fanfic, Naruto is transported to the DxD universe. His ninja skills and unique chakra system create some really cool interactions with the angels and devils in the DxD world. He has to adapt to the new rules and powers there, which makes for an exciting read.
