The story tells that on a magical continent called Amaya Deli, the seventeenth "Doran Mist" (savior) - "Glandon Jersey" suffered incurable persecution and turned into what people call a demon who betrayed the world.
When he was about to be executed, he was rescued by his former elf companions using illusions, and he disappeared from the mainland ever since.
Half a year later, three human adventurers headed by Irene Sylvie came to the borderland and found the fallen Jersey. What she brought to Jersey was a name that was enough to wake him up...
After that, the savior who bore the name of the devil reappeared in the eyes of the world.
Is the one who returns the savior who brings light and salvation to the world, or the new demon king who falls into darkness and attempts to dominate the world...?
The darkness has not been dispelled, when will dawn come...?
