A fanfiction might explore a story where the Occult Research Club members are all transported to a different dimension.

This would also test the bonds between the characters in a whole new setting.

One idea could be a new character who is a futa and has unique powers related to both male and female aspects. They could join the Gremory group and cause some interesting dynamics, like having a different approach to battles and relationships within the group.

Another could be Mittelt forming an unlikely friendship with a character from a different faction in the Highschool DxD universe.

This could lead to all sorts of plot twists as they try to bridge the gap between their two groups. And it would be really cool to see how Mittelt grows and changes through this relationship.

Well, a great storyline could involve a slave character who has a unique relationship with one of the main characters from Highschool Dxd.

This would add an element of drama and emotion to the fanfiction, as they navigate their feelings while also dealing with the supernatural elements of the DxD world.

One interesting storyline could be about a new character who has a unique power that shakes up the power dynamics in the Highschool DxD world. For example, a character with the ability to nullify all magic for a short time, creating new challenges and alliances.
