Regarding Vampires and Vampire Hunters
Intro
—In this world, there exists a darkness unknown to humans.
Immortal beings who live through the night and feed on blood—Vampires. And the 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 lost loved ones to vampires. That is why they fear, hate, and continue to hunt them.
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.
