As much as I like Sagi, I think I like Guillo more, just because. Guillo is made of win. I can't say it enough. WIN.
Anybody out there finish the game? I'm a little confused, if not creeped out, by what Sagi did what he did near the end, re: Guillo. I have a lot of questions to be answered.
In retrospect, I should have given Sagi the Hasseleh background, given the Alfard one to Milly (who I haven't drawn yet), and done something else for Guillo. (Duhr?) I guess Hasseleh could fit Guillo though, if you squint.
These characters are really hard to draw in a streamlined, simplistic fashion. They've got WAY too much stuff going on.
No, Guillo is referred to as an 'it' in official content, but it's more feminine, so fans refer to Guillo as a female. (I know few who prefer to call it male.)
Guillo's body was either permanently bound to Tarazed and unable to be removed, or it was destroyed due to its inability to properly fuse with the machina. In either case, the head, being cloth and not machina-like material, would have been unaffected, so that's why Sagi took it.
