A mechanical puppet from Ishgria made by a scientist from another world. Based on the techniques used to create the ancient "Six Armors" series, Sixgear was equipped with the same exact self-evolving capabilities as the Six Armors. It is also believed that its weapons and armor were designed to withstand battles against demons as well, making its basic functions far superior to that of its predecessors. Nevertheless, the sole purpose of this machine was to get its hands on one of the ancient Armors in order to evolve.
