Each episode contains a different design with detailed styling, reminiscent of Manga. In the second season, this is further emphasized by the image of a manga background appearing in each episode. A large number of scenes were made available on the official website for early access and review; 32 of these are available to view and download. Character designs, action scenes, and music all use the signature style of anime. Each episode also reprinted a specific scene from the manga. The show had no voice actors, and all dialog was performed with either extreme lip syncing or with Japanese language text displayed on screen. d2c66b5586
