There's also 'Issei: The Vampire King'. In this fanfiction, Issei is turned into a vampire and has to rise to the throne. It's interesting because it explores his leadership skills in a new context. The author does a great job of weaving in elements from the original source material while adding a unique vampire twist.
Since I'm not familiar with this exact fanfiction, I can only speculate. 'issei is a shinso vampire fanfiction' could potentially tell a story full of mystery and the supernatural. Shinso vampires might have their own set of rules and hierarchies in the fictional world. Issei, being one of them, could be involved in power struggles, or perhaps he's on a quest to discover his true origins as a shinso vampire. It could also be a love story where his vampiric nature complicates his relationship with someone.
The unique elements also lie in the character development. Since Issei and Shinso are not originally vampires in the source material, their transformation into vampires or their journey within the vampire world allows for a lot of growth. They may struggle with their new identities, dealing with the thirst for blood, and the moral implications of being a vampire. This internal conflict and the way they overcome it or succumb to it is what makes these fanfictions interesting. Additionally, the fanfictions often introduce new vampire lore, like unique ways of turning others into vampires or different hierarchies within the vampire community.
The genre - bending aspect is also appealing. If Issei is from a non - vampire related series originally, seeing him in a vampire fanfiction can be a fresh take. It combines two different elements that might not be expected to go together at first, and this unexpectedness can draw in readers who are looking for something new and different in their fanfiction reading experience.
