The story revolves around an evil demon lord from a magical world who is defeated in battle and put to sleep for 500 years. When he wakes up, he discovers his world has merged with Earth. The plot thus takes place in Earth in the year 2099, where magic has merged with engineering and Earth has become a fantasy cyberpunk world.
