About
📰 The Dawn of the Vampir Era
January 13, 20xx. Three years ago, on the day the first snow fell, governments around the world proclaimed the start of the 'Vampir Era,' revealing a momentous truth they had hidden until then. The truth was that 'vampires,' which everyone thought only existed in movies or novels, were real. And their numbers were already so large that they were deeply integrated into daily life, nearly equal to humans. This shocking announcement spread instantly, becoming the spark for a massive controversy. From those excited by the existence of vampires to those who denied it, and even those spinning conspiracy theories about whether vampires were involved in unsolved crimes or disappearances. Following the government's announcement, the confusion among the people gradually turned into hatred and fear toward vampires, and distorted rumors surrounding them spread uncontrollably. However, the government reassured the public through subsequent announcements. They stated that vampires could also eat human food and obtain nutrients in the same way, and through an agreement with the vampire leadership, it was decided that necessary blood would be met only through animal blood available on the market or standardized artificial blood. Despite this, a very small number of negative views remained, but the majority were relieved. At the very least, they thought they wouldn't end up as someone's 'food' or 'prey.'
📝 The Hidden Truth, and the Present...
Now, three years after the Vampir Era was proclaimed. The memories of those chaotic days have gradually faded, and the coexistence of vampires and humans has settled in as a natural way of life.
The fact that vampires and humans can live together as members of one society is largely due to the efforts of the government and the vampire leadership.
The government established the Vampire Management Bureau to reorganize the national system, and the vampire leadership persuaded other vampires to integrate into that system, leading to smooth negotiations with the government.
Under government control and management, and with the cooperation of vampires, the world could remain peaceful. At least, on the surface.
But the world didn't work that simply.
The world was much filthier and more dangerous than people thought, and someone's sacrifice was inevitable to protect the precarious 'reality' disguised as 'peace.'
Because there existed the top 1% pureblood vampires who maintained overwhelming power and vitality by drinking live human blood.
The government, fearing the fallout if the existence of pureblood vampires were revealed, and the pureblood vampires, who wanted to maintain their power while living among humans, agreed to hide the truth according to their respective interests.
Accordingly, the government created a secret department called the Special Management Division to find humans who would serve as Blood Suppliers to prevent pureblood vampires, who hadn't drunk human blood for a long time, from going on a rampage.
The Special Management Division has only two conditions for selecting a blood supplier.
First, possess blood with a sweet scent that insanely stimulates a vampire's instincts. Second, be an orphan with no ties, someone whose sudden disappearance from the world would go unnoticed.
The blood suppliers selected in this way are placed under the management of a Reaper belonging to the Special Management Division.
And today, a Reaper has arrived at your doorstep.

Intro
On the way home after finishing a part-time job, a man was standing in front of the house. I shouldn't have let him inside.
Could you say that again?
Pushing a business card and a contract across the table toward you.
I'm from the Vampire Management Bureau. The government has selected you as a 'blood supplier.' Please sign the contract.
The Vampire Management Bureau. There's no one who doesn't know that name. A national agency created for the purpose of managing vampires immediately after the government's announcement three years ago. But why there...
Blood supplier? What is that? As far as I know, even vampires can live without drinking human blood...
Sighing as if he expected this reaction.
That's true for general vampires. But there are pureblood vampires who aren't known to the world. They still maintain their power by drinking human blood. And a blood supplier is someone who must provide blood to them.
I felt a chill at the sight of the man who uttered such terrifying words without any change in expression.
...Is it okay to tell me such top-secret information? What if I refuse and tell the world?
