What are some interesting ideas for 'Highschool DxD Third Devil Fanfiction'?

One idea could be a new devil character arriving at Kuoh Academy with a unique power that challenges the existing power dynamics among the devils there. For example, a devil who can manipulate time in small increments during battles, which would make for some really intense and strategic fight scenes.

One idea could be a story where the main character, a human, discovers a unique power that allows them to hold their own against devils in the 'Highschool DxD' universe. They use this power to protect their school from devil threats that the regular characters might not be able to handle easily.

One idea could be an OC Devil who has a unique power related to time manipulation. For example, they can freeze time briefly in battles, giving them an edge. Another could be an OC Devil from a long - lost noble family trying to reclaim their family's honor and status within the Devil society. They would have to face many challenges and rivalries along the way.

One interesting plot idea could be a new character introduced in the fanfiction who has a unique power that disrupts the power balance in the High School DxD world. For example, a devil with the ability to nullify all other devil powers temporarily. This could lead to a lot of interesting conflicts and alliances as different factions try to either use or get rid of this new character.

One idea could be to focus on the characters' relationships outside of the main plot. For example, how the students interact during normal school days, like study groups or after - school clubs. Another idea is to create an alternate universe where the rules of the dxd world are slightly different in the high school setting, which could lead to new adventures and challenges for the characters.

Well, you could write a fanfiction where Fafnir discovers a hidden power within himself. He might struggle to control it at first but then learns to use it for good. Or perhaps a story that focuses on Fafnir's relationships with the other characters. For example, his friendship with Issei could be developed further, showing how they support each other in different situations. Also, a fanfiction about Fafnir getting involved in a magical tournament would be exciting.

A good concept for 'highschool dxd harem fanfiction' could be a time - travel story. The harem and Issei could be sent back in time and have to navigate the past while also dealing with their feelings for each other. They might meet younger versions of themselves or their predecessors. Another idea is to have a mystery element, where something strange is happening in the school and the harem has to solve it together. This could bring out different sides of each character and also develop their relationships further.

One idea could be exploring a new character's journey in the Highschool DxD human world. Maybe a transfer student who has a unique power or ability that shakes up the status quo among the devils, angels, and fallen angels. They could start off as an unknown and gradually form alliances and rivalries.

One idea could be a story where the characters from High School DxD are reimagined as toddlers, and their innocent interactions lead to comical and heartwarming situations. For example, Issei might be chasing after a butterfly instead of chasing girls in his usual way.

A third idea could be a fanfiction where Gaara becomes a devil himself. He could bring his ninja skills and his sand abilities into the devil society. This would change the power dynamics in the DxD highschool as he would be a very different type of devil compared to the existing ones, with his own moral code and way of doing things.
