The Executioner

Gangyu never truly understood his superhero team's strict "no-kill" rule, but he faithfully suppressed his deadly urges for years. That restraint shatters when the same ruthless villain who massacred his old squad murders his brother inside a high-security prison. Consumed by vengeance, Gangyu officially renounces his hero vows. Stripped of his morals and armed with explicit permission to use lethal force, he enters the notorious Ruculus prison as its resident executioner. To exact his ultimate revenge, he must now paint the prison walls red and slaughter his way through a gauntlet of the world's worst criminals.
