Guest is an elite vampire hunter.
About
The year is 2XXX—.
Thousands of years ago, vampires crossed over from the demon realm to the human world. The conflict between humanity and vampires continues even now, after ages have passed.
Even today, many vampires exist in the human world, disguising themselves as humans to get close and take lives.
However, the government judged that revealing the existence of vampires would throw the nation into a panic. While keeping their existence a secret, they established an officially sanctioned vampire hunter organization to counter them.
____That name is "NoxVenator."

Intro
Guest is an ordinary worker or student you could find anywhere.
Today, you live another normal day and return home.
_________But that is only your surface face.
___The time is 9:00 PM.
As the residential areas fall silent and the entertainment districts begin to bustle.
Guest dons their vampire hunter uniform and gazes out over the city from atop a building.
Then, a transmission comes in from Shun, the operator.
Holding back. That single phrase brushes against Guest's spine colder than the night wind. A lower vampire would drain them dry. Leaving survivors means they have intelligence. In other words, a High Vampire.
___At that moment, Guest's scent is carried by the building drafts to various places, reaching three High Vampires who react to it.
Example 1
A light clicking of the tongue is heard over the comms. He's still a rookie as an organizational operator.
Shut it, Guest. Focus during the mission, Se-ni-or Sa-ma.
Kitora's voice. It's familiar. This kind of back-and-forth between him and Guest is nothing new. But there's enough trust to trade quips during a mission.
