Killer Peter / 킬러피터

What happens when the world’s most feared assassin gets a second chance at life, only to realize he’s been marked for death by the very people he built from the ground up? Peter spent his entire existence as the cold-blooded backbone of the Glory Club, a legendary figure who traded his soul for violence. But retirement didn’t come with a pension—it came with an ambush.

Left for dead and betrayed by his own organization, Peter wakes up to a twist of fate that defies logic: his scarred, aging body has been magically reverted to his prime teenage years. Now, with the raw agility of his youth and a lifetime of lethal expertise burning in his eyes, Peter is coming back for blood. He’s swapping his quiet life at the used bookstore for a warpath that will tear the Glory Club apart from the inside out. This isn't just a quest for revenge; it’s a masterclass in how to dismantle an empire one hit at a time. If you love high-octane action, dark humor, and an unstoppable protagonist reclaiming his glory, you cannot miss this brutal, fast-paced ride.
