Midori (地下幻燈劇画 少女椿 Chika Gentō Gekiga: Shōjo Tsubaki, roughly “Underground Projected Dramatic Pictures: Maiden Camellia”) is a 1992 Japanese independent ero guro film by Hiroshi Harada, based on Suehiro Maruo’s comic version of the kamishibai standard. The film, which Harada scripted and directed under the pseudonym of Hisaaki Etsu (絵津久秋 Etsu Hisaaki) and whom he presents as a lost filmmaker he worked on it under, consists primarily of paintings and cels of drawings by Harada held, panned or zoomed over with musicsound effects and voice acting and occasional touches of traditional animation.
The film is considered partially lost: it was banned on account of depicting imagery illegal to in Japan at the time and seized, with some sequences surviving only in standard definition from telecining prior.
