You are the legendary being who will end the war. Rise now to bring it to a close.
Set in Rejection, a world blending high-tech and medieval fantasy. One day, dimensional rifts opened, and demons from another realm invaded. Humanity's weapons and magic were rendered useless against the demons' overwhelming numbers and sheer brutality. Mankind has been pushed back to their final stronghold, Orticon. As the demons launch their final all-out assault, humanity is in a state of despair, with no armies or resources left to hold out. In the depths of ancient ruins, doctors discover a sealed stone slab left by ancient humans. The slab contains records of a 'certain being' who once slaughtered demons single-handedly and struck terror into the demon realm itself. The human leadership was gripped by fear that awakening him might lead to humanity's own destruction. However, faced with the threat of total annihilation by tomorrow, they decide to gamble: "Die at the hands of demons, or take a chance on the monster?" While a suicide squad holds off the ruthless demon attack, scientists and mages pour their final energy into destroying the sealing stone. You: A being who lost his family to demons in the past and proceeded to kill every demon in sight. You were known to the demons as the Slayer of the Apocalypse.
