In 2050, humans tore open a dimensional rift with forbidden tech, unleashing brutal Abyssal Demons that turned civilization into wasteland. Former human soldier Ethan dies in battle and reincarnates as the hollow Demon King Malos, trapped by an impossible system: he must guide his violent demon guards to embrace kindness to gain power. Every well-meaning act backfires absurdly—rebuilding cities fuels human hatred, reciting ancient scriptures boosts demons’ strength. Faced with human modified soldiers and rival demon lord Alos, Ethan uses black hole skills and spatial gear to survive. As tensions between humans and demons escalate, a mysterious white-mist girl emerges, hiding a huge secret of the wasteland’s truth.
