They left him to rot in a shallow grave after he refused to pull the trigger. Now, the syndicate’s most ruthless cleaner has crawled back out with a single goal: to make sure no one is left standing when the debt is finally paid.

Betrayed by the syndicate he once bled for, Kang-ho Han is back from the grave with a scorched-earth policy. He isn’t just looking for justice; he’s looking to dismantle the world's most elite fighting circuit from the inside out.

In a city where light is the only currency, Kaelen is the premier 'Shadow Reaper' for the underworld’s most ruthless syndicate. But when he consumes a shadow that doesn't belong to a human, he uncovers a conspiracy that could plunge the world into eternal night.

In the concrete pits of Neo-Seoul, pain is the only currency that matters. Kang Jun was born with a rare condition that leaves him unable to feel physical pain, making him the ultimate 'human punching bag' for the city's deadliest betting rings. But when the mob tries to rig his final match, the man who feels nothing decides to make everyone else feel everything.

Jin-woo was the 'Kingmaker'—the genius strategist who put the city's deadliest gang leaders on their thrones. But after a brutal betrayal leaves his brother in a coma, Jin-woo steps out of the shadows to tear down the empire he built, one bone-shattering punch at a time.

The legendary 'Asura' retired from the gang wars to work a quiet graveyard shift at a convenience store. But when a new syndicate targets his neighborhood, Jin-woo realizes that some debts can only be paid in blood.
