When Isaac regains consciousness, oblivion isn't what awaits him—instead, he plummets into a nightmare. He awakens in a mirror world where his own reality has fractured: interdimensional rifts spawn ravenous monsters at an alarming rate, and humanity has seventy-two hours before total annihilation. Only hunters—ranked F through SS based on their awakened abilities—can stand against these abominations. Isaac's curse? He's trapped at the bottom: an F-rank hunter, orphaned and powerless, watching from the periphery as elites wage their desperate war. Then his existence shatters completely. His consciousness is violently ripped away and cast into an alternate dimension where dragons reign supreme and humans exist solely as enslaved livestock. Scarred and nearly destroyed, Isaac recognizes the horrifying truth: this realm of suffering isn't a hallucination—it's a harbinger of what's to come. Survival demands adaptation. A mysterious power awakens within him—a system that grants him the strength of every beast he defeats. [*Ding* Physical attributes acquired. Absorb?] Yesterday's weakness becomes today's lethal advantage. Isaac pursues a singular obsession: exposing the connection between these two worlds while eliminating anyone standing in his path. Armed with a katana and carrying knowledge that could reshape everything, Isaac rejects the slave's existence he was assigned. To live through what's approaching, he must transform into the apex hunter—the only way to prevent the cycle from beginning anew.
