世间共分四部分,神界、魔界、冥界,还有人间。自从有天地以来,四界一直和睦相处,但后来神、魔、冥界为了各自在人间的利益,从而明争暗斗,最后由冥界挑拨,引发了神魔两界有史以来的第一次圣战,战争持续了五个月,最后以魔界战败而告终。——摘自《魔神战史》 The world is divided into four parts, the world of gods, demons, the underworld, and the world. Since the heavens and the earth, the four worlds have been living together in peace, but later the gods, demons, and the underworld struggled for their own interests in the world, and finally they were provoked by the underworld. This triggered the first jihad in the history of the devils and the war continued. Five months later, they ended up defeating the Devil. - From “The History of Devil Wars”
