In a world where dungeons erupt across Earth and monsters ravage the land, humanity clings to survival through Hunters—chosen ones blessed by the System. But when Rei Kurozane awakens without a class, weapon, or skills, he's cast aside as worthless.
Until his first kill.
Devouring the flesh of a dying beast, Rei discovers a hidden evolution path—"Predator Class: Unknown."
He doesn’t gain experience from slaying monsters—he must eat them.
While others grow stronger through training, Rei evolves by consuming the very essence of what he kills. Flesh. Blood. Soul.
But every bite threatens to strip away his humanity…
As the world watches S-Rank heroes rise, one forgotten outcast becomes the true terror lurking in the shadows.
Not a savior.
Not a hero.
But the Devourer.
