Jail - a living prison for humans, buried 666 meters underground.

 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.

 Separated, they are each drawn to the devouring Jail that floats in the sky...

 This is the finale to the tale of the Blood Maidens.
