Cultural Invasion In Another World
A vampire can live on two things: blood or worship.
Zed Nolan dies at his desk in the middle of crunch and wakes up in a coffin. He is now the Blood Duke, a thousand-year-old vampire lord who is about to starve his whole clan to death. There's no money for blood. And the Church of Holy Light will burn every one of them the moment somebody preaches a sermon, raises an altar, or bites a neck.
So how do they live?
Simple. Nobody ever said worship had to come from a sermon. Where Zed comes from, it comes from a fandom.
So the vampires go into show business.
Before long, the Pope meets the Blood Duke face to face, and the first thing out of his mouth isn't "purge the heretic." It's "when is the next Sherlock Holmes?" The vampire hunters swear all day that every last vampire has to die, and spend all night at the theater on their third trip through the Dark Knight trilogy. Even the emperor next door is in Zed's shop, emptying his treasury one card pack at a time for a single limited-edition card.
Short films, movies, games, cliffhangers, card packs, fads, the internet. Every one of them makes Zed stronger.
And when an ancient god finally wakes, and the whole world braces for the end, the god speaks.
"You misunderstand. I only wanted to ask when I get to be a champion in League of Legends."
"Oh. Then take a number. You're 1,145th in line."
