Ten years after a brutal monster invasion claimed his family, Itsuki seeks justice by finally undergoing his hunter awakening. However, the result is a systemic anomaly: he unlocks the mysterious "Order Breaker" job with a level permanently fixed at zero.

His journey reveals a deeper layer of conflict, involving corrupt elite families like the Kinoshitas and a looming level-100 disaster predicted by global prophecy. By utilizing passive range expansions and critical hit artifacts, Itsuki evolves into a lethal paradox—a hunter who remains at level zero while systematically dismantling the world's most intelligent disaster beasts
