Manga creator Tsukasa Hojo's debut live-action film. 'Angel Sign' is Hojo's debut as a director, which is made by editing a number of short films into one movie. Hojo directs the "Prologue" and "Epilogue" stories, while a different director will handle each of the other stories, which were selected in Silent Manga Audition. All the stories will have no spoken lines, and will only have video and music.
