Six years after the ChäoS;HEAd incident, Shibuya is gripped by a fresh wave of bizarre, ritualistic deaths that the press dubs New Generation Madness. High schooler and amateur newspaper writer Takuru Miyashiro starts digging into the killings alongside classmate Serika Onoe, only to find his own memories of the original disaster are less reliable than he thought. This manga adapts the same visual novel as the TV anime, condensing its central mystery into four volumes.
