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.
One great Highschool DxD Issei magic fanfiction is 'Issei's Magic Evolution'. It shows Issei developing unique magical abilities that are different from his usual power set in the original series. This adds an interesting twist to his character.
Another reason is the fan community. Highschool DxD has a large and passionate fan base. When a fanfiction focuses on Issei and magic, it combines two elements that many fans are interested in. Fans like to share and discuss these fanfictions, which further spreads their popularity. Also, it allows fans to explore their own ideas and interpretations of the characters and the world, which is always appealing.
It would probably be really interesting. Naruto's skills and abilities as a 'god' would likely disrupt the normal flow of the Highschool DxD world. Maybe he'd use his ninja techniques in battles against the devils and angels in that universe.
Rias could also be a popular character. She is a powerful devil and her leadership skills could be put to the test in a story that combines Highschool DxD with the God of War. Maybe she has to negotiate with the God of War characters or lead her group against a common enemy from that realm.
Well, it could be really intense. Naruto has his powerful jutsu and abilities. If he were to kill a character in DxD, it might start with a misunderstanding or a power struggle. For example, if the DxD character underestimated Naruto's power, it could lead to a quick and unexpected end for them. Maybe Naruto would use his Rasengan or Sage Mode to take on the DxD character.
A possible plotline could be a battle royale - style story where characters from both God of War and DxD are pitted against each other in a tournament. The winner gets some ultimate power or prize.
Yes, in some Harry Potter fanfictions, there might be the concept of a 'god of magic'. Authors often take creative liberties to introduce such powerful and otherworldly entities to add new layers of mystery and power dynamics to the wizarding world they're building upon the original Potterverse.
One common theme is friendship and alliances. Naruto is known for making friends and in the DxD fanfiction, he might form new alliances with characters from DxD. Also, the theme of self - discovery. As Naruto enters a new world, he has to learn about himself in this different context. For example, how his ninja way might change or stay the same. And of course, there's often the theme of combat. Since both series have a lot of action, seeing Naruto fight in the DxD world against different opponents is a big draw for these fanfictions.
One interesting concept could be the unique powers an original character (OC) might possess as a god. For example, they could have the power to manipulate time on a grand scale, which would add a whole new dynamic to the story. Another concept might be how the OC god interacts with the existing characters in the Highschool DxD universe. They could form alliances or rivalries that change the course of the story.
