Welcome to The Warden of the Forbidden Zone: The Contract Era, a world of childhood nostalgia shattered beyond anything you could imagine.
Here, Bear Ridge is no longer a forest filled with laughter. It has become a twisted sea of trees that devours life. Logger Bald Qiang put down his chainsaw long ago and now guards this hellish border alone. His contract beast is a mysterious black cat, and late at night he is always heard murmuring to two unmarked graves. There sleep the legends known as Xiong Da and Xiong Er.
Bikini Bottom has sunk beneath the deep sea, never to see daylight again. SpongeBob sealed himself inside a metal diving suit and has wandered the abyss for a century, all to suppress the cosmic behemoth his dear friend Patrick Star has become. Every time he makes a 'happy bubble' to heal pain, he forgets a precious memory. By now, he can barely remember how to smile.
The Green Grasslands have become an endless maze of light and shadow. A shepherd walks through it, the bell around his neck the last relic of the Sheep Village. His contract beast is his old nemesis, Grey Wolf, a loyal companion he won at the cost of his soul. Every time he rings the bell to unleash an absolute defense, he mourns his lost comrades once more.
As the three great guardians maintain a brutal balance, a boy emerges from a shelter. Lin Xiao bears the secret of his missing older sister, and with a Starry Sky Sheep contract beast capable of glimpsing fragments of time, he steps into this dark world overrun with monsters and divided among warring factions.
He will discover that every sacrifice, every mutation, every act of madness stems from an ancient plan spanning three forbidden zones. And he himself is at the heart of it all.
This is no fairy tale...
