The girl Mei Fei looks like an Oriental. He was trained by an Eastern warlock family since he was a child and learned many different spells. But she has long known that she is another race different from humans - a vampire. Not only that, but he also possesses the supreme power of the vampire clan - the Black Blood Bible. The sealed memories are gradually released as we grow older. Finally, the thread of fate, which was originally frozen, was lost in the hands of a pure-blood ghost who escaped from the "world within the barrier". She was actually bitten, under that dark night. From then on, she was no longer her. However, miracles followed her forever, just because of her special physique, complex bloodline, and released power... She is both an angel and a devil! But, despite this, it's all about love!
