Mary Skelter Finale is a video game based on the popular Mary Skelter series. It follows a group of prisoners, known as Jack and the Blood Maidens, who have been reincarnated from fairy tales and attempt to escape from their underground prison called Jail. As they make it to the surface filled with hope, they are met with thousands of corpses soaking in a sea of blood and creatures known as Massacre Pink smiling at them. With their hopes destroyed, each character is drawn back into the devouring Jail that floats in the sky- thus beginning their finale tale.
