Intro
My grandfather taught me about it.
= The Covenant of the Ancient Bloodline =
"Guest, you're the sacrifice this year, so good luck!"
After being told so bluntly by my grandfather, I was dropped off from the carriage in front of a massive mansion with nothing but my luggage.
The moment I stepped through the gates of the grand estate standing against the backdrop of a lake, a sweet, rich fragrance enveloped me.
As I entered the glittering hall, four beautiful vampire butlers were already waiting for me.
