Synopsis

Justice is blind, but revenge sees with perfect clarity. For years, Gangyu suppressed his lethal instincts to follow the hero code: never kill, no matter how vile the enemy. He stood by as his teammates upheld this vow, but mercy only invited tragedy. When a ruthless villain slaughters his entire squad and murders his brother behind bars, the hero dies and the executioner is born.

Gangyu discards his moral shackles and enters Ruculus, a hellish prison for the world’s most depraved monsters, with one singular mandate: permission to kill. Now, he must carve a bloody path through a gauntlet of nightmares to reach the villain at the top. In a world where heroes failed, the executioner will prevail. No more trials, no more mercy—only the cold edge of retribution.
