Vampire is kinda on the down low these days. Everybody know the drill, they're OP bloodsucker, but nerfed heavily or instantly killed by the sun, silver, holy water, and onion. Not to mention UV rays which is imitation of Sun rays.
Nowadays we have seen hundreds of long living powerful beings such as dragon, demon, Demi Human, Demi God, Werewolf, Elf, Spirits, Orc, and such that are powerful and can stand by during the daytime. They don't have apparent weakness other than scarce population and more powerful enemies.
In comparison to them, Vampire Is more similar to Human-Bat demihuman.
Not to mention the existence of Human with capabilities of Wizard, Witch, Magician, Magus, Occultist, Knight, Holy Knight, etc.which were qualified to fighting them, and these days those powerful humans already fighting among themselves as those beings were all human with powerful toys. And human meet human equal conflict in the end.
Vampire that are strong yet contain so much weakness and limitations is not that interesting. Usually some author choose to remove all the weakness and the bloodsucking trait, making them another "Beautiful/Handsome Human" with monster abilities.
So please avoid Twilight-like stories, we have hundreds of those fanfic running around.
Realistically, if you write something like Vampire LitRPG which include [Vampire System] which make the [Host] experience the live of vamprie tricking human to suck their blood while Looking for potential followers and slaves, maybe we will read (?) If you put interesting title, cover, and description.
Or just write "Reincarnated to AliceShiki Dating Simulator with Villain System [LitRPG] [Survival]" and call it a day.
It really depends on how good the implementation tho.
