Mary Skelter reaches its final chapter! Jail – a living prison for humans, buried 666 meters underground. It appeared suddenly several decades ago, giving birth to monsters called Marchen and patrolled by madness-inducing Nightmares. A group of prisoners, Jack and the Blood Maidens, were reincarnations of fairy tales who dared to escape. They climbed from the bottom of the tower up to the surface, filled with hope… But outside were thousands of corpses soaking in a sea of blood. There stood beings known as Massacre Pink, smiling. In that moment, hope was destroyed. The group was torn asunder, with Jack and the Blood Maidens scattered to their own paths.
