Reincarnated as the only one Lucifer's and Leviathan's grandson, Acheron Lucifer is born into a world without God—yet carries the blood of devils. A pure-blooded-devil, and destined for unimaginable power, he wields the Demonic Brilliance of Evil Light and the Sea Serpent of the End to forge his own path.

Surrounded by allies, rivals, and a family steeped in betrayal, Acheron seeks to transcend his lineage—and challenge the very divine. In a world where the weak perish and only the strong survive, only the bold dare defy Gods themselves.

Will the True Morning Star rise… or set the world ablaze in his wake?
