Naruto could be a game - changer. He'd likely become a powerful fighter. His rasengan and other jutsu would be very effective against the enemies in the DxD world. Maybe he'd be seen as a new type of supernatural being due to his chakra. He might also use his ninja stealth to gather information about the various factions, which could be crucial in preventing wars between them.

With his ninja skills, he could easily sense danger and protect civilians. He could also introduce the concept of ninja villages to the DxD world. This could lead to new forms of cooperation and governance. And his own story of growing up as an orphan and becoming a hero could inspire the characters in DxD who are also facing their own challenges.
He could be a sort of outsider who comes in and shakes up the status quo. Naruto's unique powers would make him a force to be reckoned with. He might initially be confused by the different rules and power systems in Highschool DxD but quickly adapt. For example, he could use his shadow clones to gather information about the different groups and their motives. And his positive attitude could inspire some of the characters in the Highschool DxD universe to change their ways.
She might be a mediator between different factions.

Naruto could be a disruptor of the status quo. In the Highschool DxD world, there are set power structures and politics. Naruto, with his straightforward and often naive view of right and wrong, would likely not abide by some of the more underhanded practices. He'd probably be a force for good, using his ninja skills and Kurama - enhanced power to protect the weak.
God Ichigo could be a game - changer in a Highschool DxD fanfiction. He might act as a mediator between the different factions. Given his experience with different types of spiritual beings in the Bleach universe, he could bring a new perspective to the ongoing conflicts in DxD. For example, he could try to stop the senseless fighting between the devils and angels, which is a common theme in DxD.
Well, in such a fanfiction, Naruto's skills and personality would bring a lot of changes. His ninja abilities like shadow clones could be used in creative ways in the Highschool DxD world. Maybe he'd use them to attend multiple classes at once or in battles against the devils and fallen angels. Also, his never - give - up attitude would surely influence the characters in the DxD world, leading to some interesting character developments and new alliances.
Genesis could be a rival. He might compete with the main characters for power or the affection of certain characters. His competitive nature and his desire to prove himself would make him a formidable rival. He could also have his own group of followers or allies within the school, creating a new faction that the main characters have to deal with.
In the Highschool DxD fanfiction world, Naruto with the Juubi's power could be seen as a wildcard. His arrival could change the political landscape. For instance, if he sided with a particular devil family, it could shift the balance of power. His ninjutsu skills would be a mystery to the DxD characters at first, and they would have to learn how to work with him. He could also introduce new concepts like the ninja way, which could inspire the DxD characters to reevaluate their own beliefs and fighting styles.
His character would develop in his relationships. Naruto is very friendly and outgoing. In Highschool DxD, he'd meet all kinds of characters. He could start off being a bit naive about the romantic and power - related relationships in the school. But as time goes on, he'd learn how to handle them better. For example, he might have to deal with the complex relationship between Issei and the various female characters. This would make him more mature in handling relationships and also more empathetic towards different situations.
In the school in Highschool DxD fanfiction, Superman could be a protector. He would use his powers to keep the students safe from any threats, whether they are from the supernatural world or just normal human dangers like a fire or a bully. He might also be a role model for the students, showing them what it means to have a strong moral compass.
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.
