Takumi Nishijou is a high school otaku who spends most of his time playing online games and watching anime, often experiencing delusions and feeling like he's being watched. The series of murders known as the "New Generation Madness" in Shibuya doesn't interest him, but his life takes a turn when he receives a disturbing image of a man being stabbed to a wall from a user named Shogun. This image eerily matches the scene that unfolds before him in reality, including a pink-haired girl covered in blood. Takumi is left questioning the nature of reality as he becomes entangled in the "New Gen" murders.
