One idea could be to explore how magecraft is integrated into the school curriculum in the Highschool DxD universe. Maybe there are special magecraft classes for the devils, angels and fallen angels. Another idea is to create a character who is a magecraft prodigy and see how they interact with the main characters like Issei. Also, a story about a lost or forbidden magecraft spell that the characters have to find or protect could be really engaging.
First, you need to be familiar with the Highschool DxD universe, especially the rules and concepts related to magecraft in it. Then, come up with an interesting concept or plot. It could be something as simple as a character learning a new magecraft spell. Next, create your characters. They can be original characters or existing ones with new traits. Start writing the first chapter, setting the scene and introducing the characters and the initial situation related to magecraft.
One popular theme is the combination of different magic systems within the High School DxD universe. For example, mixing the traditional magic of the devils with magecraft from other sources.
An OC (Original Character) in a Highschool DxD fanfiction having the Rinnegan could be an extremely powerful and unique addition. The Rinnegan, from the Naruto universe, brings a whole set of abilities like the Six Paths powers. In the context of Highschool DxD, this OC could use these powers in various ways. For example, the ability to see chakra could be translated into seeing the magical energy in the DxD world. They could use the gravitational powers of the Rinnegan to manipulate the environment during battles against devils, angels, or fallen angels. It would make for a very interesting and overpowered character in the Highschool DxD fanfiction setting.
One aspect to consider in a Venelana fanfiction could be her relationship with other characters in the Highschool DxD universe. For example, how she interacts with her family members and how that affects the overall plot. It could also explore her backstory more deeply, perhaps her life before the events of the main story.
Yes, there might be. There are a vast number of fanfictions out there for various combinations of popular culture elements.

In Highschool DxD multiverse fanfiction, character development can take on new dimensions. New relationships can be formed between characters from different universes. This can lead to some really creative storylines. For instance, a character from a more peaceful universe might have to team up with a battle - hardened character from another universe, and they learn from each other's experiences.
One idea could be that Naruto is somehow transported to the world of Highschool DxD. He could use his ninja skills and chakra in the new world, maybe even teach some of the characters there a thing or two about combat. For example, he could show Issei how to better control his power using chakra control techniques.
There could be. Fanfiction writers are known for their wild and creative crossovers.
