One possible scenario in this fanfiction could be that Vampire Rosario Mizore and Sub Zero find themselves in a strange, new realm. Maybe they initially see each other as threats due to their very different natures. Mizore, being a vampire, has her own set of powers like enhanced speed and the ability to charm, while Sub Zero has his ice - based powers. However, as the story progresses, they might realize they can help each other in some way, perhaps to defeat a common enemy that threatens both of their worlds.
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. It could be a new adventure for Tsukune or a different take on his relationships.

They could then go on a journey to find a way to send Mizore back home, while also having adventures and fighting off various threats along the way.
