Story

A curse dyes the moon red. It's as though it were an apple dipped in blood. Mysterious incidents in which vampires are killed one-by-one in the human world began to occur. The feuding brothers of the Sakamaki, Mukami and Tsukinami households started to suspect and become cautious of one another. As a result of this, the equilibrium of the spiritual world gradually headed towards collapse. Then, there is the lone and maddened young boy who lead the mysterious, decaying beings of the spiritual world. Who will be the one that'll get their hands on the bloodstained paradise (Eden)?
