One common theme is his growth as a character. Fans often like to write about how Issei becomes stronger both physically and mentally. Another theme is his relationships, whether it's his romantic relationships or his friendships with other characters in the series.
One common theme is his relationships, whether it's with his friends or potential romantic interests. Another is his growth as a character, in terms of strength and maturity.
Themes like love and friendship are quite common. Their relationship can be seen as a blend of both. There's also the theme of self - discovery. Issei, for example, discovers more about his powers and his place in the supernatural world. Rias also has her own journey of self - realization. Additionally, the theme of protecting what they cherish, like their friends and the world they live in, is often explored in these fanfictions.
The theme of self - discovery is also common. Issei in many fanfictions is on a journey to find out more about himself, his place in the world, and his true potential. And of course, the theme of the supernatural world and all its elements like magic, different species, and ancient secrets is often a big part of these fanfictions as it was in the original Highschool DxD.
Power and responsibility are also common themes. Since Highschool DxD has a lot to do with supernatural powers, in fanfictions with Issei and Elmenhilde, they often have to deal with the power they possess and the responsibility that comes with it. For example, they may have to use their powers to protect the school or the innocent. And there's the theme of loyalty. They show loyalty to each other, their friends, and their respective factions, which is often explored in different ways in different fanfictions.
Power - up themes are also quite common. Issei often gets new powers or abilities, and Rias may play a role in that. For example, in some fanfictions, Rias helps Issei to master a new form of his Sacred Gear. This not only strengthens Issei but also deepens their bond as they train together. Another aspect is the exploration of the supernatural world in the context of their relationship. Since Highschool DxD has a rich supernatural setting, fanfictions may expand on this, like how Issei and Rias face new threats from the underworld or other dimensions together, which further cements their relationship and showcases their individual growth.
Another theme is adventure. Since Highschool DxD has a lot of action and supernatural elements, fanfictions might have Issei and Akeno going on adventures together, facing powerful enemies and overcoming challenges as a team. They could be fighting against other devils, angels or fallen angels in these stories. And often, these adventures also contribute to the growth of their relationship.
Well, often in Highschool DxD Issei bashing fanfiction, a common theme is power redistribution. Since Issei is a central figure in the original in terms of power - up and his role in battles, these fanfictions might shift the focus to other characters getting stronger or more important in different ways. It could also be about changing the overall tone of the story. Instead of Issei's more comical and pervy attitude driving parts of the plot, the fanfiction might have a more serious or different comical approach by removing or reducing his presence.
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.
One common theme is the exploration of their relationship in a supernatural setting. Since Highschool DxD is full of demons, angels, and other mythical beings, their relationship might be affected by these elements. For example, they might have to fight together against a common enemy, which would strengthen their bond.
Power - up is a common theme. Since Issei becomes a Dragon God, the fanfictions often explore his new powers and how he uses them to overcome challenges. Another theme is relationships. His relationships with other characters, like Rias and his friends, might change due to his new status.
