Prologue: Vampire Night

The city of Tokyo sleeps, vampires agree. What they want to suck blood? This answer only lies with themselves supernatural beings that dominate the Japanese capital at night to quench their thirst, they will not go out completely.
 A high school student, sweet, polite, with black hair that went below the waist and of medium height called Shiori Kuramassa returned home following a single path that hitherto had no presence of any vampire. But halfway through, she was startled by a loud and apparently came back strong, which led her to a poorly lit alley. The girl was terrified, therefore, could not ask for help and not defend themselves, because her hands were immobilized and her legs were shaking, barely able to stand upright. He closed his eyes, not to see the end of it.
 After a few minutes, she felt a slight hole in the neck, made by thin and sharp fangs, who sucked her life slowly. Suddenly, he realized that the vampire which attacked Tomaro she stopped her blood. There was dead, Shiori knew it very well, but also did not understand why he stopped so soon. Slowly opened his eyes and saw that her executioner looked at her curiously, and with a touch of admiration.
 - Who are you? - He asked, authoritarian.
 - My name is Shiori Kuramassa - she replied, still frightened.
 - How old are you? - He said, trying to remember her name.
 - 15. - She said, a little more calm.
 - Your blood is very sweet, but I do not remember you. You can leave, but know that from now on you will no longer be free.
 - What do you mean?
 - You are in my possession. Anyone who tries to have you as a wife will fail, because from the moment my fangs touched your skin, I can make two choices: I can either kill you or I can allow you to stay alive, but with the proviso I have you as my wife one day. - As soon as he finished speaking, the boy looked at Shiori, who was sitting on the floor, motionless - What are you doing there? Go away shortly before I change my mind!

 Soon, the girl stood up, still stable and returned to the path that led her back home. She was killed because she lost something she always craved: eternal freedom.
