聖痕 ～牙と贄と狂喜の館～

Roan is a young man with amnesia. He lives quietly in the old castle in the eastern Romania with his maids. The older maid Rachel substitutes mother to him, and the younger Cartier adds vivid colors to the life.

Such peaceful life lasts till tortured mummies of parents are found in the basement. The gears of fate start rolling like crazy...
