Shiiro is a little boy, but he is not just an ordinary boy. He drinks blood. In other words, he is a blood sucking creature or what we called vampire. Well, everybody knows that vampires might be handsome/pretty, attractive and deceiving but they're completely dangerous. And that's why his Aunt decided that he would just take home schooling. Shiiro grew up in his Aunt's care. When he reached 16, curiosity wrapped him, he begun to look for his parents. He even wondered why he is not with them and why he can't remember the face and names of them. That's the time when he decided to go to school, to explore the world and to look for clues that could may lead him to his parents' side. While studying in that school he actually can't believe what he saw, one of his classmate is the same kind as him, her name is Luna. Can Luna help him in his way to those important persons or will be a great antagonist in his life.
