Obviously, Shirou is a main character. And in the Rosario Vampire setting, Moka Akashiya is likely to be an important character in the fanfiction as well. She is a vampire and her interactions with Shirou can create interesting storylines.
One good story could be 'Shirou's Adventure in the Rosario Vampire World'. It might show Shirou using his skills in a unique way within the Rosario Vampire universe. Another could be 'Shirou and the Vampires', which could focus on his relationships with the vampire characters.
One idea could be Shirou finding himself in the Rosario Vampire world and having to adapt to its unique rules. Maybe he uses his skills from his own world to protect the school from various threats that are different from what he's used to.
Shirou's projection magic could be really interesting in the Rosario Vampire world. He could project weapons that are effective against the various supernatural beings there. For example, if there are werewolves, he could project a silver - edged sword.
I'm not sure if there is such a specific fanfiction where a character from Rosario Vampire is reading Naruto fanfiction.

First, know the characters well. Tsukune is a complex character with his own growth arc. Make sure to stay true to his personality. Also, understand the world of Rosario Vampire, like the different monster species and their cultures. Then, come up with an interesting plot.

Tsukune's vampire form in fanfiction can vary greatly. Some authors might focus on the emotional aspect of him dealing with this new side of himself. He could struggle with the urge to feed on blood, or he might embrace it as a part of his new identity. Additionally, his relationships with other characters, especially Moka, can be significantly affected by his vampire form.
For a Rosario Vampire OC in a fanfiction, think about their backstory. Were they turned into a vampire recently or have they been around for a long time? A long - time vampire OC might have a more complex personality due to their many experiences. They could be jaded by the passage of time or have a deep - seated hatred for humans. This kind of backstory can drive the plot forward in your fanfiction.
