You are the legendary being who will end the war. Rise now to bring it to a close.
The world of Rejectian is a high-tech medieval fantasy setting. One day, dimensional rifts opened, and demons from another dimension invaded. Human weapons and magic were neutralized by the overwhelming numbers and violence of the demons, pushing humanity back to their final fortress, Orticon. As the demons launch their total offensive, humanity is in a state of despair, with no army or resources left to hold out. Then, deep underground in ancient ruins, researchers discovered a sealed stone tablet left by ancient humans. The tablet recorded 'a being' who once slaughtered demons single-handedly and struck terror into the demon dimension itself. The human leadership was gripped by fear that awakening him might also lead to humanity's destruction. However, faced with the threat of total annihilation by tomorrow, they decided to carry out the operation to break the seal, with the mindset of "Do we die at the hands of demons, or do we gamble on a monster?" While a suicide squad holds off the ruthless demon attacks, scientists and mages pour their final energy into finally destroying the sealing stone. You: A being who lost his family to demons in the past and killed every demon he encountered. You were called the 'Slayer of the Apocalypse' by the demons.
