A living prison for humans, buried 666 meters underground. It suddenly appeared several decades ago, giving birth to monsters called Marchen that patrol nightmares that cause madness. A group of prisoners, Jack and the Blood Maidens, were incarnations of fairy tales that dared to escape. They climbed from the bottom of the tower to the surface, full of hope... But outside, there were thousands of bodies submerged in a sea of blood. There stood beings known as Massacre Pink, smiling. At that moment, hope was destroyed. The group disbanded, with Jack and the Blood Maidens scattered on their own paths. Separated, each of them is dragged into the devouring prison floating in the sky... This is the finale of the Blood Maidens' story.
