Saber Marionette Z
The controversial "Saber Marionette Z" story didn't make it as an animated series. It was released in Vcomi, a section of the AnimeV (Gakken), the series was not sold as a whole comic book, the serial was released from April, 1995 to December 1995. Originally, the SMZ was intended to be the OVA sequel for Saber Marionette R, but it never materialized, only a manga was made. The manga that was released only had 7 chapters, on the 6th chapter the character designs were completely changed and the final chapter was released as an incomplete novel. Satoru Akahori and Katsumi Hasegawa attempted to re-compose the stories and tried to release the novel SMR2, but it was never realized and was released as another novel.
The SMZ story takes place 100 years after the SMR (Saber Marionette R) time line, it is the time when all marionettes were created with otome kairos, but the otome kairos were all incomplete, many marionettes never reach maturity and some even went berserk. A scientist, called Professor Kitajima tried to solve this problem, but he died and left his research unfinished. Now, his daughter (also called Professor Kitajima) continues the research and sets off to find the "Inheritance of Face", which will supposedly help resolve the situation.
This story is named after a new Saber Marionette. Her name is Zero, a rather advanced and powerful prototype model. She also has the capability of fusing or combining with other marionettes by using the tentacles on the back of her head.
