In a world in which there are two moons, one black and one white, there are many rumors and myths that travel across the land - Tales such as that of the Sleeping beauty in the rose forest, of demons that eat away your dreams and of the black moon falling from the sky.

In recent years demons known as Zerom have come into existance which feed off the dreams of humans. By doing so they rot away the human soul, the human heart, known as "Spiria" and cause them to fall into a grave, uncurable illness. To fight against these Zerom beings, there is a maze, created by the power of human hearts, known as the Spell Maze. Within this maze lie mystical weapons, known as Soma, and only they can fend off these Zerom and cure the uncurable disease.
