In a world where reality is rewritten by an unknown system, Ryo, an ordinary man, finds himself trapped in a deadly survival game that follows the rules of a novel only he has finished reading. As Hunters and Beasts roam the ruined city, slaughtering anyone in their path, Ryo must navigate alliances, betrayals, and the unseen forces controlling the game.
But when he discovers the brutal massacre of the people he once sought to protect, he realizes that the rules he thought he understood are beginning to change. With no clear enemies or allies, and a lurking presence more terrifying than the Hunters themselves, Ryo must decipher the truth before he becomes the next victim.
The only thing keeping him alive? The knowledge that he alone knows how this story ends.
