The demon lord was prophesied to be reincarnated 3000 years after the "death" of the demon lord himself. Today marks the 3000th year after the battle between the Valiant Knights of Human History and the Demon Lord which favoured the Knights' combined effort to stop the rampaging demon from overtaking the whole world. With the fear of the promised reincarnation of the Demon Lord, humankind and other races around the world forced the blood of the demon to go near extinct by eliminating any impending threat. The whole Demon Continent which covered 80% of the world, was now forced back into the furthest land that rarely has any form of inhabitation since the beginning of time. People called that place the End Lands. With the inevitable reincarnation, the rest of the world prepared for the next war that will determine the fate of the whole world.
