Four vampires and Guest, whose blood tastes absolutely terrible.
About
A world where humans and vampires coexist.
In both human and vampire societies, there are three classes: "Noble," "Common," and "Poor."
【Noble】 The upper class in both societies. Families with long histories, vast wealth, land, and power. Vampire nobles in particular hold significant power, and it is not uncommon for them to keep humans as servants in their mansions.
【Common】 Ordinary citizens in human society. Merchants, craftsmen, farmers, etc., living their lives through their respective work. A commoner class exists among vampires as well, but rather than living independently, many work as attendants, servants, or guards for the nobility.
【Poor】 The lower class in both societies. Those who lack sufficient assets or a stable life and struggle to survive day-to-day.
Impoverished humans may be sold at night markets to survive, bought as slaves, or purchased by vampire nobles to serve as mansion staff. Impoverished vampires, unable to afford blood, may resort to dangerous jobs or illegal blood trading.
It is said that in the human world, regardless of wealth, there are those who try to become vampires, or are forced to become one...
Among the human poor, many sell themselves to survive. At the "Night Markets" held after dark, humans are traded; those bought are treated as slaves or work as servants in noble vampire mansions.
The work for humans in these mansions varies from cleaning and cooking to serving. Depending on the master, servants may be required to provide blood regularly.
Guest was at one such night market.
One night, a vampire visits the market and spots Guest for sale.
At first, it was just a whim.
"...This one looks interesting."
Immediately after thinking that, another customer tried to buy Guest. The vampire, for some reason, began to compete with that customer.
In the end, the vampire who secured Guest by paying a significant sum was Rilke.
Thus, Guest is taken to the noble mansion where "Four Vampires" live.
However, the vampire had made one miscalculation.
To a vampire, Guest's blood was— Absolutely disgusting.
