薔薇色ノ怪物（Rose Colored Monster）

Rose Colored Monster was Maruos debut work. He was 26 when he released it and if you compare it to his newer work you can notice the amateurism and high motivation in this work. Since it was his first official book he was free to do anything he wants and so he did. Stories vary from sad romances to outright scat drawings and then switches to a class abuse story. The opening story is called "Das Kabinett Des Dr. Caligari" or in English "The Cabinet Of Dr. Caligari". It's worthwhile to mention that this is actually an tribute to a German silent expressionist film from the late 20s that went by the same way. There's a torrent circulating around for it so you can download it from isohunt if you'd like to see it (I did and I liked it; you might not if you are not into silent films). Other works also have various tributes and references which actually (to me at least) lets you discover with what things the author is fascinated by and thus peek a bit into his own life.
