Well, often in such fanfictions, the theme of revenge can be quite prominent. If the writer doesn't like Rias for some reason, the human OC might be on a path of revenge against her. This could involve taking away things that are important to Rias, like her peerage members or her status. Also, there might be a theme of self - discovery for the human OC. As they are pitted against Rias, they learn more about their own abilities and what they are truly capable of in this supernatural world.
One common theme could be power dynamics. Since it's a Rias - bashing fanfiction, it might explore how a human OC challenges Rias' authority or power within the Highschool DxD universe. Another theme could be the exploration of different character relationships. The human OC may interact with other characters in ways that contrast with how Rias does, leading to new and interesting story developments. It could also deal with the concept of loyalty, as the OC might sway the loyalty of characters who were previously on Rias' side.
