Highschool DxD SI Harem Fanfiction: What are some popular plotlines?

One popular plotline could be Naruto being transferred to the Highschool DxD world and his ninja skills making him stand out among the devils and angels. This leads to various characters being attracted to him, forming the harem. Another could be Naruto having to use his chakra to solve the power struggles in the DxD world while also dealing with his newfound romantic interests.

One interesting plotline could be the main character using their gaming knowledge to gain unique abilities in the Highschool DxD world. For example, they might apply strategic thinking from games to outwit opponents in battles.

Perhaps a plotline where the characters in the harem form a sort of alliance to protect Ophis from other threats in the 'Highschool DxD' universe. They could train together and develop new powers or abilities.

A crossover with 'One Piece' is also quite common. Just imagine the chaos that would ensue if the Straw Hat crew landed in the world of Highschool DxD. Luffy's carefree attitude and his powerful devil fruit abilities would be a great contrast to the more serious and power - hungry devils in DxD. And of course, his nakama would surely get involved in the harem situation in some way. Maybe Nami would be interested in the treasures that the devils possess, or Sanji would be chasing after the female characters in DxD.

There are quite a few out there. For example, 'My OP Life in Highschool DxD'. In this fanfiction, the self - insert character has some extraordinary skills that help them navigate through the complex world of Highschool DxD. They might be able to use magic in a way that no one else can, or have a special connection to the supernatural elements in the story. Another great one could be 'Highschool DxD: OP SI's Impact' where the self - inserted character has a significant impact on the overall plot and relationships of the original story.

Well, 'A Different Highschool DxD Issei Harem' is quite well - known. In this fanfiction, the author gives a unique take on how Issei forms his harem, with different character interactions compared to the original story. There's also 'Issei's Harem: The Unseen Tales' which reveals some unseen aspects of the relationships in Issei's harem.

Well - developed harem characters can be achieved by showing their growth over time. For instance, a character who was initially afraid of fighting could gradually become more confident and skilled. Their relationships with other characters in the story, not just the SI, should be explored. For example, a character might have a rivalry with another in the group which later turns into friendship. And don't forget about their reactions to different situations. A character might respond with humor in one situation and with deep thought in another, showing different facets of their personality.

Issei Hyoudou can also be a popular character in these fanfictions. His growth from a normal human to a powerful devil is an interesting arc. In Si Sitri fanfiction, he could interact with the Sitri family in various ways, perhaps getting involved in their schemes or forming relationships with the Sitri characters.

The popularity of Highschool DxD yuri harem fanfiction is due to the unique combination of elements. The Highschool DxD world already has a large and diverse cast of characters. When you add the yuri and harem aspects, it creates a lot of potential for different relationship dynamics. Fans are interested in seeing how the female characters interact in romantic or semi - romantic ways.

Rias Gremory would be a popular choice. She's a strong and important character in the Highschool DxD world. Her leadership and power could be a great contrast or complement to the SI's gamer - like abilities. Another could be Akeno Himejima. Her mysterious nature and powerful attacks could create interesting interactions with the SI. The SI could help her unlock new abilities using their gamer knowledge.
