Rei is just another anonymous lurker in the comment sections of manga sites-until one night, he's thrust into a terrifying role he never asked for: warning readers to stop at Chapter 99 of the popular series *Flesh and Shadow*. A cryptic message warns that unless he can convince enough readers to heed his advice, he will be punished by an otherworldly force tied to the story itself. With a countdown ticking down and a chilling creature hunting him, Rei must navigate a twisted game of survival, using fear and manipulation to stop the flood of readers unaware of the horrific fate awaiting them. But as time runs out, Rei discovers the horrifying truth: in this story, the readers aren't the only ones in danger.
