I've been a Five Star Stories fan for many years. I have most of the English translated Mangas. For those that don't know, Five Star Stories (FSS) is a sci-fi Manga created by Mamoru Nagano starting in the late 80s. Nagano was a fashion designer at some point and it shows in his designs.

Anyway, Maegera is a "Fatima" which, described simply, is an artificial life-form created to sort of "copilot" one of the big mechs known as "Mortarheadds"
