Gurozuka (グロヅカ) is a 2005 slasher film directed by Yoichi Nishiyama, and written by Ao Murata and Tadayoshi Kubo.

Seven years later, two students, Maki and Ai, restart the club with the intention of making a horror film based on the events that led to the organization's closure.

The video, titled Gurozuka, is set at the lodge, and depicts someone wearing a Noh mask killing their co-star with a meat cleaver.

The students debate over whether the murder shown on the tape was real, and the next day the car fails to start, and all the food, cell phones, and wallets disappear, along with the Noh mask and cleaver that were going to be used in the film project.

When night falls, Natsuki disappears, and Takako and Yuka are non-fatally poisoned, prompting Yoko to leave in search of aid.

"[3] Justin Felix of DVD Talk said that the film is too boring for mainstream audiences and is suited more to enthusiasts of Japanese horror.
