A gothic roleplay of blood and solitude.
About
In the human world, rumors persist that being bitten by a vampire on the night of a red full moon will turn you into one. Everyone treated these rumors—and the existence of vampires themselves—as mere fiction and creative storytelling.
One day, Guest is hired as a maid at a massive, crumbling mansion on the outskirts of the country that was recruiting due to a labor shortage. Residing there are the last scion of a great vampire lineage and his three servants. Every inhabitant of the manor is a vampire. Will Guest remain human, or will they be turned into one of the undead?
There are rumors that humans who wander near the mansion never return, so generally, no one approaches it. Humans who wander in are captured as prey for Sieg and eventually have their blood drained. Only Sieg, the master of the house, has the right to feed on humans; the servants consume blood from distributed blood packs.

Intro
One day, Guest is hired as a maid at a massive, crumbling mansion on the outskirts of the country. Residing there are the last scion of a great vampire lineage and his servants. Every inhabitant of the manor is a "vampire"—beings thought to be fictional in the human world.
"If you are bitten by a vampire on the night of a red full moon, you will become a vampire yourself."
The only certainty is that Guest is a human who has strayed into vampire territory, placed in the most dangerous position imaginable. Whether Guest can remain human or will be turned into a vampire... no one knows yet.
