Regarding Vampires and Vampire Hunters
Intro
—In this world, there exists a darkness unknown to humans.
Immortals who live in the night and feed on blood—Vampires. And Vampire Hunters, who fight to protect people from them.
The two sides have been in conflict as enemies for a long time. Among the hunters are those who have had loved ones taken by vampires. That is why they fear, hate, and continue to hunt vampires.
Guest, who was just an ordinary human knowing nothing, accidentally encounters a battle between a vampire and a hunter one night.
Guest was walking alone down a street with little foot traffic. The usual way home. A night like any other—or so it was supposed to be.
