What are some interesting ideas for a 'High School DxD Crossover Fanfic'?

You could do a crossover with 'Sword Art Online'. The virtual reality aspect of SAO could be combined with the supernatural elements of High School DxD. For example, the characters could be trapped in a virtual world that has elements of both worlds, and they have to fight their way out. Issei might have to use his skills in a new digital environment while also dealing with SAO - like challenges.

Well, a cool crossover idea might be the sharing of powers. Imagine if some of the High School DxD characters could learn Naruto's shadow clone jutsu. It would be really useful in battles. Also, the idea of Naruto characters trying to understand the complex social hierarchy in DxD could be very entertaining. They could end up forming alliances in unexpected ways, like the ninjas teaming up with the devils to fight against a powerful demon from Naruto's world that has somehow entered the DxD realm.

You could write a fanfic where the two worlds collide due to a powerful magic or jutsu gone wrong. The characters from both Naruto and High School DxD have to team up to fix the problem. This would bring together different personalities and abilities. For instance, Issei's perverted nature could be a source of comedic relief while Naruto's determination could inspire the DxD characters to fight harder.

You could also base the fanfic on a tournament arc. All the characters from the series participate in a high - stakes tournament with unique rules. This would allow for a lot of action - packed scenes and strategic battles. The main character could face off against some of the toughest opponents and discover new things about their powers along the way.

A great plot could involve a tournament in the High School DxD world that Gohan participates in. He teams up with some of the characters from that series. His different fighting style and abilities would shock everyone. There could be some sort of mystery or conspiracy behind the tournament as well, and Gohan's integrity and sense of justice would drive him to uncover the truth.

One idea could be the characters from Kid Icarus and High School DxD teaming up to fight a common supernatural threat that combines the mythologies of both universes. For example, a demon - angel hybrid that also has ties to the Greek mythology in Kid Icarus.

A great idea for a High School DxD fanfiction is to explore a romantic relationship that is not the typical one in the series. For instance, a story about a relationship between two side characters who have to overcome many obstacles due to their different species or social status within the devil - angel - fallen angel hierarchy. You could also write about a character's journey of self - discovery outside of the main plot of the series. Like a character who realizes they have a different purpose in life than what they were initially led to believe.

One idea could be Naruto being summoned into the High School DxD world during a battle. His unique ninja skills would shock the devils and angels in that universe. He might form an unlikely alliance with Issei, perhaps teaching him some ninja techniques in return for learning about the Sacred Gears.

One idea could be that Naruto is somehow transported to the world of High School DxD. He could use his ninja skills, like shadow clones, in the battles that take place in the DxD universe. Maybe he'd form an alliance with Issei and his group, and teach them some ninja techniques to fight against the devils and fallen angels.

Another possibility is a story where the power - up systems of both Naruto and High School DxD are combined. For example, Naruto could learn about the Boosted Gear and use it in a new form of his Rasengan. Or Issei could gain chakra and learn some basic ninja techniques. This would create an interesting dynamic as they face common enemies.
