Once I Possess the System, I Will Become the Creator – Full Story Summary

Life can change in an instant. For Kano Hoki, an ordinary office worker and game planner, that truth comes crashing down harder than he could have ever imagined. His story begins in a familiar world, where he works tirelessly to bring his ideas for new games to life. But reality is harsh—his proposal for a new title is flatly rejected, and not long after, he is fired from the company he dedicated himself to. Left feeling powerless and dejected, Hoki tries to find comfort by speaking to his online friends, explaining the painful results of his failed career.

That is when everything shifts. Suddenly, the words “Final Chapter” flash across his monitor, and in front of his very eyes, a horde of terrifying monsters emerges. The scene is eerily familiar, because it is not random—it mirrors the very game concept he had once created, the very idea his company rejected. Confused and horrified, Hoki has no time to process what is happening. The monsters begin wreaking havoc, and he rushes home in desperation to protect his parents and sister. But when he arrives, it is already too late. His family has been killed, their lives taken by the same monsters that should have existed only in his imagination.

Grief gives way to rage. Heartbroken and furious, Hoki fights against the monsters, but he is just an ordinary man, not a warrior or a hero. He is overwhelmed quickly, and in the chaos, he is stabbed to death. As life slips away, guilt consumes him. His own creation, the world he had once dreamed up as a game, has destroyed reality itself. All he can do is wish for an afterlife, some chance to escape the crushing burden of responsibility.

Yet death is not the end.

When Hoki opens his eyes again, he finds himself in an entirely different place—a schoolyard, filled with strange sights and unfamiliar people. The world around him is not the one he left behind. It is different, shaped by forces beyond his understanding. Above him in the sky hangs a terrifying reminder: a countdown. It displays the days left until the end—190 days remain before the world will once again fall into chaos and destruction.

But this time, something is different. Along with his rebirth in this new world, Hoki has inherited a mysterious power, one that ties directly to his past as a game planner. He is no longer just a powerless man—he has become the “Creator.” With this power, he gains access to a system that allows him to shape, design, and control aspects of the world itself, almost as if it were the game he had once planned. It is both a gift and a responsibility.

For Hoki, this is his second chance. He failed once, losing his family and dying without redemption. Now, with the system in his hands, he must prevent the apocalypse that looms over this new world. Each decision he makes, every strategy he applies, carries the weight of countless lives. He must balance his knowledge as a former game designer with the challenges of surviving in a reality where the stakes are far higher than they ever were in front of a computer screen.

The journey ahead is not simple. The countdown to destruction ticks away, and danger lurks at every turn. Monsters roam the land, dungeons hide unimaginable threats, and powerful enemies seek to use the chaos for their own gain. Hoki cannot rely solely on brute force—his physical strength is limited—but his true weapon lies in creativity, planning, and the system that gives him the authority of a creator.

Along the way, Hoki begins to gather allies. Some are drawn to his intelligence and strange abilities, others are simply caught up in the same struggle for survival. Through these connections, he slowly learns what it means not only to lead but also to trust again. The grief of losing his family never leaves him, but the bonds he forms in this new world give him fresh reasons to fight.

At its heart, Once I Possess the System, I Will Become the Creator is more than a survival story. It is about responsibility, redemption, and the weight of creation. Hoki is not simply battling monsters—he is battling his own past mistakes, the guilt of unleashing destruction, and the fear of failing again. The countdown above him is more than a reminder of the apocalypse; it is a constant pressure that forces him to grow stronger, smarter, and more determined with each passing day.

The action in the manhwa is fast and creative, blending epic battles with clever use of Hoki’s system-based powers. Readers watch as he experiments with his abilities, creating solutions that no ordinary fighter could manage. His background as a game planner becomes his greatest strength, turning the logic of gameplay into real-world tactics for survival.

But what makes the series truly compelling is its emotional core. Hoki’s drive is not about glory or fame—it is about making sure no one else suffers the way his family did. Every step he takes is guided by that loss, and every victory is a small step toward redemption. His determination to rewrite fate and prevent the end becomes the force that keeps him going, even when the odds are overwhelming.

For fans of apocalyptic fantasy, survival adventures, and protagonists who rely on brains as much as power, this manhwa offers a refreshing and gripping story. It delivers high-stakes tension, heart-pounding action, and a protagonist who feels both flawed and deeply human.

In the end, Kano Hoki is no longer just an office worker. He is the Creator, a man given the tools to reshape reality itself. Whether he can truly prevent the apocalypse this time remains uncertain—but one thing is clear: he will not stop fighting until he has used every last day of the countdown to rewrite the fate of the world.
