The full moon shines in the sky. In the light, a red shadow runs like gust. Holding a Japanese sword in his hand, he jumps from a building to a building. He's running, in order to retrieve his brother, in order to realize his dream, and... When he identifies the enemy, he grins with shining his fang because he knows he can beat any enemy now. The Special Area - it is the only place where the vampire, which is supposed to exterminate, and the human beings can cohabitate. In the place, when two vampires, Mochizuki Kojiro and his brother Kotaro, and a human being, Katsuragi Mimiko, meet together, their new fates begin to hatch.

The story of life and death colored by black and red, and the vampires that transcend them begins. You'll be the witness of the legend of bloody race living in the shadow.
