Shadow leveling
Sung-style underdog taken to the extreme: Elias Crowe was once a promising D-rank Hunter trainee—until a betrayal in a high-risk Gate left him crippled, his mana core shattered, and labeled "permanently unawakened." Disgraced, broke, and mocked as "the living corpse," he survives by taking the dirtiest jobs: bait duty, corpse disposal, anything the real Hunters won't touch.
During what should have been his last raid (a suicide mission to pay off crushing debt), Elias dies... briefly. In that darkness between life and death, something ancient answers: the fragmented will of a forgotten Shadow Monarch, granting him the "Shadow Leveling" system. No grand tutorial, no OP start—just a brutal mechanic: every time he kills (or nearly dies), he can steal a fragment of the enemy's shadow, converting it into experience, stats, or summonable shadow soldiers. The catch? He starts at Level 0—no skills, no gear, no mercy—and dying for real means permanent erasure.
Elias claws his way back from the bottom: soloing goblin nests, outsmarting parties that once abandoned him, building an unstoppable shadow army one corpse at a time. As he rises, old enemies resurface, Guilds take notice, and the system evolves in terrifying ways—unlocking necromantic powers, shadow teleportation, and the ability to "level" entire battlefields by turning fallen foes into his legion.
Fueled by cold revenge against those who left him to die, Elias vows to become untouchable. But the deeper he dives into the Gates, the clearer it becomes: his power isn't a gift. It's a curse tied to an apocalyptic prophecy—and if he reaches the top, the world might burn in shadow.
