Shokei Sareta Kenja wa Lich ni Tensei Shite Shinryaku Sensou wo Hajimeru

The Sage Dwight and the Hero fought side by side to vanquish the Demon Lord, ending an era of darkness that had threatened to consume the world. Yet their triumph was met not with gratitude, but with betrayal. Fearing the immense power Dwight wielded, those he saved falsely accused him and his companion of becoming the next Demon Lords. Cast out as traitors, they were thrown into the Valley of the Dead to perish in obscurity. But death could not claim the Sage. Though his flesh rotted away and his bones were left bare, a burning grudge against the treacherous world refused to let his spirit fade. Reborn as a Lich, Dwight now harbors a singular vow: to utterly deny and destroy the unjust society that condemned him. Wielding magical might that eclipses even the fallen Demon Lord of old, he raises an endless legion of skeletal soldiers from the cursed earth. Driven by vengeance and commanding an army of the dead, Dwight prepares to unleash a devastating war of conquest upon the very world he once sacrificed everything to save.
