"Why am I forgotten from the whole world?" War between the five races on earth - the humans, the "Demonic Race", the "Wild God Race", the "Spirit Race" and the "Phantom Beast Race"- has ended in the victory of humans. It is said that "Prophet Sid" had sealed the other four races in the black pyramid now called "Crypts".
