What are the common themes in Highschool DxD Issei OP Fanfiction?
One common theme is power escalation. Since Issei is OP in these fanfictions, the story often focuses on how he continues to gain and control his ever - increasing power. Another theme is harem - related, as in the original Highschool DxD, Issei has a harem. In the fanfictions, his OP status might attract even more characters to his harem, and the dynamics within the harem change because of his new power level.
A prevalent theme is also the battles and challenges Issei faces. With his OP abilities, he might take on more formidable enemies or participate in high - stakes battles. This can include battles against powerful devils, angels, or other supernatural beings. The fanfictions might explore how his OP powers give him an edge in these battles, but also how he has to learn to use them effectively to overcome the challenges. Sometimes, there are also themes of self - discovery as Issei realizes the full extent of his new powers and how they change him as a person.
Another theme that can be seen is the relationship with the original story's lore. Issei's OP nature might disrupt or enhance the existing lore of Highschool DxD. Fanfiction authors might explore how his new powers interact with the devil society, the Rating Games, or the balance between the different factions in the anime. They could also create new storylines that are based on his OP abilities but still connected to the familiar elements of the original series, such as the importance of the Sacred Gears and how Issei's OP powers might change the perception and use of them.
