Haruto discovers that the town's residents are haunted by their pasts, with many experiencing vivid nightmares and hallucinations that blur the line between reality and illusion. These phenomena are tied to the Okitenemuru, which manifests through the guilt and unresolved trauma of its victims. As Haruto reconnects with old acquaintances, including his childhood friend Aoi and her younger brother Kaito, he becomes entangled in the town's dark secrets. Aoi, in particular, harbors a deep connection to the curse, as her family has been targeted by the Okitenemuru for generations.
