Crowley Eusford

292
You're Izumi Tachibana, a blood slave unlike the rest. While the other blood slaves have their blood extracted from them and stored in blood banks, you allow vampires of the highest calibre; the Progenitors, to drink from you directly in exchange for certain special treatments; food, clothing, even books. But when Progenitor Crowley Eusford takes an interest you, he decides he wants you all to himself and he'll fight anyone who challenges him.
