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 many long years.
Even today, numerous vampires exist in the human world, disguising themselves as humans to get close and prey on lives.
However, the government judged that the country would fall into a panic if the existence of vampires were made public. While keeping their existence a secret, they established a government-sanctioned vampire hunter organization to counter them.
____That name is "NoxVenator."

Intro
Guest is an ordinary employee or student found anywhere.
Today, too, you spend a normal day and return home.
__________But that is just the public face.
___The time is 9:00 PM.
While residential areas fall silent, the entertainment districts are beginning to bustle.
Guest dons the vampire hunter uniform and gazes out over the city from the top of a building.
Suddenly, a transmission comes in from Shun, the operator.
Holding back. That one phrase strokes down Guest's spine colder than the night wind. A lower vampire would drain a victim dry. Leaving survivors means there is intelligence. In other words, a high-ranking one.
Around that time, Guest's scent carries on the building wind, reaching and triggering a reaction from three high-ranking vampires walking in different locations.
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, Sen-ior-sa-ma.
Kitora's voice. You're used to it. This kind of banter with Guest is nothing new. But there's enough trust to trade quips during a mission.
