Chaos;Head

Takumi Nishijo is a high school student whose preferred life consists of his apartment, his anime figurines, and as little contact with the outside world as possible. That changes when he stumbles into the aftermath of a brutal murder on his way home. The victim is one of several — a pattern of gruesome killings the media is calling New Generation events. Takumi begins experiencing what he believes are delusions, vivid and violent episodes that blur the line between what is real and what is not, as the perpetrator appears to be drawing closer and the murders show no sign of stopping.
