Manga creator Usamaru Furuya announced on Tuesday that he and photographer Hirokazu Kobayashi will launch a project to adapt Furuya's manga into live-action form.
The first phase of the project will be the release of the Amane Gymnasium concept art book, which will feature photographs. The project is based on Furuya's manga of the same name. The announcement did not state if the overall project will involve a screen adaptation such as live-action film or television series.
Shown below are some images from the art book, featuring Shōhei Hashimoto as Felix (second picture below) and Hisanori Satō as Johanne (third picture). The pictures were taken at the Bebenhausen Monastery in Germany.
