CHAOS;HEAD NOAH

CHAOS;HEAD NOAH follows Takumi Nishijo, an isolated high school student in Shibuya whose routine is disrupted by a series of gruesome murders. After receiving an image that appears to predict a killing, he encounters Rimi Sakihata at the crime scene and becomes caught up in the mystery.

This visual novel is told largely through Takumi’s perspective as he encounters unsettling clues, suspicious characters, and events that leave him questioning what is real. Its psychological-horror and science-fiction mystery explores paranoia and the gap between perception and reality.

At key moments, the Delusion Trigger lets you steer Takumi toward positive or negative delusions, or choose not to indulge one. These choices affect scenes and can lead toward different routes; additional character stories and endings become available as you progress.

Players who enjoy the game often praise its unsettling murder mystery, atmosphere of paranoia, and twists that make them question Takumi’s account of events. The Delusion Trigger is a recurring highlight for giving readers a way to shape his perceptions, and some reviewers also value the protagonist’s characterization, voice acting, and music. Reactions are mixed: several reviewers find Takumi difficult to tolerate or the early story slow, while others consider those qualities part of the experience.
