lunasia (girls' frontline)

Though her precise origins were unknown at first, clones of hers with altered memories would be sent on a quest for vengeance against G&K, resulting in their deaths. Upon recovering one of the bodies and discovering the similarity her brain appeared to have to a T-Doll's Neural Cloud, Persica went ahead and scanned the corpse's brain, utilizing the data to create a Neural Cloud model. She would lend a copy to former colleague Lycoris, who'd go on to create Elisa with it, while Persica would use the model to create the AR Team, using varying amounts of the scans for each member, M4A1 embodying the most, and RO635 the least, with her instead using it as a basis for the next gen of dolls, making her more stable and duplicable.

As a result of the amount of scan data that was used for her, M4A1 would be recognized by Elisa and her OGAS as "Lunasia."

The Nytos bare a resemblance to not just M4A1, but Lunasia as well, and it would be revealed that not only is the leader of Paradeus William, but that he had been the one to make the clones. The intent behind his usage of Lunasia as a cloning specimen becomes clearer from Chapter 13 on, once it is revealed that he is in fact the brother to the original Lunasia (and in turn, daughter of Rudolf von Oberstein).

The events in Cartesian Theater and Angular Gyrus (Chapter 15.2/15.4) would see Lunasia return through the possession of M4A1's body, for reasons which this wiki page is not fit to explain.
