A live-action film adaptation of Michio Yasu and Keito Aida's Dokumushi manga has been green-lit, and will open in theaters and as a Niconico live broadcast in Japan on April 9. The film's ending will differ from the manga and the original novel. The staff for the film revealed the poster, pictured right.

The film will star Ryota Murai ( Kamen Rider Decade , Doamaiger D ) and Rina Takeda (live-action Attack on Titan , Wakako Zake). The rest of the cast includes Shintarō Akiyama, Kyōka Mizukami, Kiyotaka Uji, Mao Noguchi, and Ryūsuke Komakine.

Kayoko Asakura will direct the film, and idol duo Faint★Star will perform the film's main theme song.

Aida's manga is based on Yasu's earlier net novel Kodoku . The horror manga's story centers on a group of seven people, who wake up to find themselves trapped in an abandoned school building. The building has a timer set for seven days, surveillance cameras, and pots and carving knives. Each individual must find a way to survive in the extreme situation.

The original novel and the subsequent manga debuted on the E☆Everystar app, and Futabasha published the manga's fourth compiled book volume on June 23. Futabasha will publish the fifth volume in February, and the sixth and final volume is slated for July.
