Peter devoted his entire life to Glory Club, a powerful crime organization, becoming a legendary killer before quietly retiring to run a used bookstore. His peaceful days end when Glory Club betrays him, leaving him ambushed and nearly dead. Instead of dying, Peter awakens to find his body reverted to his teenage years—restored to its peak condition. Armed with decades of experience and a body capable of carrying it out, Peter begins a calculated hunt to dismantle the organization that once owned his life. This time, he’s not a disposable weapon—he’s the executioner.
Killer Peter thrives on efficiency. The protagonist doesn’t waste time questioning his second chance—he weaponizes it. Unlike emotional or hesitant returners, Peter moves with the confidence of someone who has already lived, lost, and killed enough to know exactly what he wants.
The series balances regression fantasy with grounded crime action, making each confrontation feel deliberate rather than explosive. There’s no flashy system or power gimmick—just experience, preparation, and ruthless intent.
This webtoon is ideal for readers who enjoy revenge thrillers, assassin protagonists, and stories where competence is the real power fantasy.
