Jude, a highschool girl is attacked by a mysterious shadow- man. She awakens to find herself locked in a dark room where two options which involve life and death are given to her. To give out her blood or to be burned alive. Later, she realizes that she was a leader of ancient vampires and five thousand years ago they were all killed in a battle field and reincarnated as humans and her blood was the one which could awaken their fellow vampires and go for revenge.

“No… no… I-I don't want to… please, le-let me go…” Hearing that, the three looked at each other before bursting into laughter. They looked like they had no sympathy seeing the girl's pitiful condition. Their smiles grew even more, like enjoying a girl who was suffering. "There's no need to be so afraid, little girl. However, it's quiet here. Nobody will know what happened to you. People who know you will still think of you as an innocent girl, as long as you don't tell them…” he said in a half-whisper. Then, he signaled to the two men behind him to hold the girl's hands, so as not to trouble himself while performing his actions. “No… don't… DON'T!” The girl became increasingly desperate, she herself realized that she had previously chosen the wrong path of escape and ended up leading the men to a place that made them more free to carry out their actions. She couldn't rebel any further when her tiny hands were locked by the two men, while the other man wanted to do something wanton to her. However, before the girl's nightmare occurred, someone said "Young Lady, do you need my help?"
