In a society obsessed with bloodline purity, magic is a luxury reserved for the elite, leaving commoners in the dust. But when a demonic apocalypse wipes out the arrogant nobility, only Colin, a former slave and master swordsman, stands as humanity's final shield. Just as death claims him, a mysterious Forbidden Grimoire sends him spiraling five years back in time. Now reborn as a powerless youth, Colin possesses the lethal knowledge of the future and a cursed tome that grants magic to the unworthy. No longer bound by the chains of his birth, he will blend peerless swordplay with forbidden sorcery to dismantle the existing hierarchy and stop the coming slaughter. This time, he isn't just surviving; he's rewriting the laws of power to ensure no one else suffers his fate.
