The world ended not with a bang, but with a shudder as secret realms materialized above cities, integrating into the urban landscape and unleashing a terrifying new reality. Most succumb to the pervasive spiritual Qi, but some awaken a dormant potential within their genes, transforming into formidable Demon Slayers. 

Humanity's future now rests on strength, measured by a rigid hierarchy from Novice to Immortal Gene Demon Slayer. Cities, reduced to two continents, are powered by mutated beast cores, fortresses against an ever-escalating threat: animals mutating faster and stronger, pushing humanity towards extinction.

Seventeen-year-old Eobard Peterson, a brilliant but impoverished student, is thrust into this new order when a realm appears above his home. His agonizing awakening reveals the ancient Blood Barbarian Body, a lineage of war machines whose power once rivaled dragons. 

Driven by an unshakeable need to protect his mother and triplet brothers, Eobard masters his terrifying abilities. Witnessing mankind's struggle, he becomes a leading "counselor" among Demon Slayers, striving not just for survival, but to build academies that will forge humanity's new path, even as the world around them slowly decays.
