Transfer student Kanazawa Nobuaki has a secret--one that makes him afraid of making friends with his new class. His classmates aren't so easily pushed away, and start breaking down the wall around his heart. But it might all fall apart when the entire class receives orders for something called the King's Game.
Nobuaki begins to tell the story of the King's Game that happened at his old school to his new classmates, who have just witnessed the death of one of their own firsthand. The orders started out simple enough, but quickly escalated.
Nobuaki, Kenta, and Mizuki leave for the abandoned village where the first King's Game took place. On the trip, Nobuaki tells them what happened when he theorized that King was a member of his old class.
The death count rises as Nobuaki and his classmates try to find a way out of the game. Can they figure out the meaning of the cryptic newest order before it kills them all?
The survivors of the race barely have any time to catch their breath before the next grotesque order arrives from King. Can Nobuaki and Natsuko put their differences aside to find a way to end the King's Game?
