As this goes on, I keep on finding new ways in which Deux and the cybernewtypes were wasted. If the hints from the interview are true, Machu is this universe's Newtype Jesus, and she's barely done anything to earn it. She's not exceptional otherwise, she's fairly privileged, she makes mistake after mistake but miraculously bounces back, and she chose to be a pilot for her crush and thrillseeking. Meanwhile, Deux was whining about how natural Newtypes get everything handed to them, while she had to suffer for her powers. She earned the right to be a newtype by having the willpower to survive. It's the antithesis of Machu and Nyaan.

Second, freedom is a major theme throughout the anime. Machu, for instance, seeks freedom from her boring life and mother's/society's expectation through Shuji and kira-kira. And who is more shackled than a cybernewtype slave soldier?

Then you have all the other minor traits that make Deux resonate with the story. She's a teenage (or younger) pilot, she kira-kiras, drives a Gundam around, etc.
