God-king Veydor, warned that his newborn son Lucifer will kill him and destroy heaven, tries to kill the baby. Queen Evelyn seals Lucifer's power and hides him in the human world. At eighteen, Lucifer wins the holy trials and enters heaven, finding his enslaved mother unrecognized. He defeats demon lords, awakens his seraph blood, and saves dragon princess Selina, forming a mate bond and taming dragon Knox to get the herb curing Evelyn. But back in heaven, Veydor stabs him, Satan saves him and reveals Evelyn's torture. Lucifer falls, gathers weapon fragments, forges a god-slaying sword, kills Veydor, becomes god-king, crowns Evelyn, and reseals Satan and the abyss army.
