Across Shibuya, a string of killings known as the "New Generation Madness" drew widespread attention. As these crimes became infamous, they turned into a popular subject of conversation among locals. Nevertheless, these "New Gen" murders fail to interest Takumi Nishijou, a high school otaku who often suffers from delusions and feels constantly watched. Disregarding the real world, Takumi passes his time playing online games and watching anime. Yet his routine is shattered when he receives a terrifying image of a man pinned to a wall from a user called Shogun. After composing himself at an internet cafe, Takumi witnesses the exact same murder scene depicted in the image unfold before his eyes, accompanied by a blood-covered girl with pink hair calling out his name. Struggling with the nature of reality, Takumi finds it hard to decide whom to trust as he becomes entangled in the "New Gen" murders, convinced that the killer is targeting him.
