Xcution
One hundred years ago, the Great Experiment ended the world.
Cities fell. Civilization collapsed. Humanity survived only by retreating behind twelve colossal fortified kingdoms known as the Shinokunis, where the towering Walls stand between life and the horrors that roam outside.
Brook is a young Watchman in Shinokuni-01. Every day, he patrols the Wall, protecting a city that believes the past should remain buried. But Brook has never accepted the official story. His parents—two scientists who disappeared during the Great Experiment—were declared dead without a body ever being found, and he refuses to believe they are gone.
While everyone else is content with the safety of the Walls, Brook searches for answers.
As strange events begin to unfold—a mysterious voice beyond the Wall, hidden messages, forgotten records, and secrets buried beneath the kingdom itself—Brook realizes the greatest danger may not lie outside the Walls, but within them.
Joined by his lifelong friend Sera, veteran Watchman Crowley, and a growing group of unlikely allies, Brook is drawn into a journey that will uncover the truth behind the Great Experiment, the origins of the Shinokunis, and a history that has been deliberately erased.
What begins as one young man's search for his parents slowly becomes a battle for humanity's freedom.
Because some truths were never meant to be forgotten.
And some Walls were never built to keep monsters out.
