Born into a fallen lineage of legendary wizards, Elric Mervinger should have been destined for greatness. Instead, he is cursed by a debilitating condition that leaves him completely unable to wield magic, making him an outcast in his own home. But everything changes the day he goes looking for a cure and finds something far more dangerous: the legendary demon Mephistopheles.

Trapped by a dragon and desperate for a host, Mephisto attempts to possess Elric, hoping to use his body as a vessel for escape. The plan backfires in the most spectacular way possible. Instead of being consumed, Elric absorbs the demon, binding their fates together in a volatile, high-stakes partnership. Now, the boy who couldn't cast a single spell possesses the dark, raw power of a demon lord. With a literal devil on his shoulder and the weight of his family’s honor on his back, Elric must navigate a world of treacherous mages and mythical beasts. But in this deadly game of power, the line between master and monster is thin—and Elric is constantly teetering on the edge. Will he rise to reclaim his legacy, or will he eventually be shredded from the inside out by the very power he craves?
