The First Demon of All Time

A battered demonic cauldron, a proud young man bearing a blood feud, and an immortal legend that will reign over the heavens! In this life, since I am called a demon, I shall let demonic ways rule the world and look down on all living beings! In this life, since I must fight, I shall fight until heaven and earth are overturned, in a battle that stirs the soul! In this life, since I must kill, I shall leave corpses strewn across the land and rivers of blood in my wake! One day, across the Myriad Worlds, those called demons shall claim supreme glory!
