What wasn't ordinary with Naoto is that his right eye is a little special, it possesses a special ability, "Hunter's Eye", that make it possible for Naoto to see other people's Life Force in numerical values. But his ordinary days ended when he met a girl with such high Life Force that she couldn't possibly be human. The girl introduced herself as Raquel Alucard, a vampire. She ordered him to get the hold of the Azure. And so Naoto was dragged into a bloody battle surrounding the Azure.
