Description：
When midnight descends on Riverside Amusement Park, the rides come alive—and they're hungry. A mysterious email promises 10 million yen to anyone who survives five deadly challenges. But as amusement park attractions transform into instruments of death, the real game begins.
The pirate ship captain starts severing heads. The Ferris wheel accelerates beyond control. A giant wolf hunts through fog-shrouded carousels. With each terrifying ride, the body count rises and the survivors must uncover the horrifying truth behind this nightmare.
When Yui, a young woman, joins forces with a fearless stranger, they discover that some games have much higher stakes than prize money. As alliances crumble and true colors emerge, they'll face a final coaster ride through forests where the line between life and death becomes razor-thin. But the deepest mystery of all isn't the park—it's what brought them here, and what one person will do to save another.
