What could be an interesting plot in a 'Naruto is an Exorcist DxD' fanfiction?

One possible plot could be that Naruto discovers he has exorcist powers in addition to his ninja abilities. He then has to learn how to control and use these new powers while still dealing with the threats in his ninja world.

Perhaps Issei discovers that there are exorcist families with ties to the DxD world in ways that no one suspected. He gets involved in their internal power struggles and has to choose sides while still maintaining his loyalty to his original friends. It could lead to some intense battles and moral dilemmas.

Power-ups are a common theme. Since Naruto already has his ninja powers and then enters the DxD world with its own set of powers like Sacred Gears, a lot of fanfics focus on how he combines or enhances these powers. For example, he might learn to use his chakra in new ways because of the DxD environment.

One idea could be an OC who is an exorcist with a special power to see the true forms of devils. They could start off as an enemy to the devils in the Highschool DxD world but then gradually form alliances due to a common threat. For example, a new, more powerful and evil force emerges that targets both exorcists and devils.

One possible plot could be Naruto being summoned into the DxD world by some sort of magic accident. He might initially be confused but quickly adapt his ninja skills to the new environment. He could team up with some of the DxD characters to face a common enemy, like a powerful fallen angel or a rogue devil. His Rasengan and shadow clone techniques would be quite unique in this world.

Maybe in this fanfiction, the Nine - Tails in Naruto is actually a super - powerful Sacred Gear that was sealed within Naruto. This Sacred Gear has its own consciousness like in DxD. The story could revolve around Naruto trying to master this new form of power that is a blend of his chakra and the Sacred Gear's abilities. He would have to deal with the various factions in the DxD world who are interested in his power.

Well, a cool plot might involve Issei from Highschool DxD being sent to the Naruto world. He could learn ninjutsu there and then bring some of those skills back to his own world. He might befriend Naruto and they could work together to fight a common enemy that has somehow crossed between the two worlds, like an evil group that wants to take over both the ninja world and the world of devils and angels.

Maybe a story where the main characters from both universes have to team up to fight a common enemy. This enemy could be a powerful demon that has somehow found a way to cross over from another dimension. The Naruto characters could bring their combat skills and teamwork, while the Highschool DxD characters contribute their unique powers related to the devil and angel aspects.

One possible plot could be a crossover where Naruto characters end up in the Highschool DxD world. Naruto and his friends could be mistaken for new, powerful devils or angels. They might have to adapt to the new school system, which includes things like the Rating Game. And along the way, they could make new friends and enemies, and Naruto's skills could be put to the test in a whole new way.

A plot could involve a character from Naruto, like Sasuke, starting a new life in Highschool DxD's high school. He tries to keep his past a secret but gets involved in the peerage system. He might end up in a rival peerage and have to compete in the Rating Games. This would be full of drama as he struggles to adapt to the new rules and social hierarchy while also dealing with his own inner demons.
