Misa is an underground idol and being filmed closely for a documentary. One day, an owner of BDSM club "H" perceives Misa's potential and headhunts her as a dominatrix. Misa is confused at first, but when she meets the top dominatrix Kanon, she learns sexual pleasure she never knew. She then decides to pursue a career of both idols and BDSM.

Whatever you do, don’t avert your eyes… College girls Kanon and Rena test their fears by exploring a foreboding forest late at night, a place rumoured to harbour “magai-gami”, or counterfeit gods.

YouTuber Tomoki Uchikawa, along with his friends Hinako, Souta, and Nanae, head to the former Ishio Village, where there are rumors of people being spirited away, to film a video investigating urban legends. However, their whereabouts remain unknown, and the police discover the rental car they had rented near a tunnel on the outskirts of the village. The video cameras left behind there show shocking images of locked houses, children in armed uniforms, imprisoned adults, and adults being infected by a strange disease, a rotten demon, that occurs on the night of a new moon.
