i wonder why there isnt anymore doujinshis about this show?
Several reasons orignal animes dont tend to translate well Flip Flappers being both the most difficult and simple. Its easy to recreate the characters and do what you will with them however text and art will never match the orignal feel of the show its probly the only anime to take advantage of every possable aspect of animation even useing aspect ratio to kick you out of imersion or designing the world in a way to express the space in a 2d plane with other layers being used to create depth without allowing the viewer to forget you are wathing a tv show. (Both are used so rarely it might be the first time in years either has been used properly letalone the same time) TL:DR (its hard to translate a story built to be supported by animation, sound, music, ect into pictures and text)
