She mingles the most appealing traits of the two classic animu waifus, as much a ferocious Asuka as a waifish vulnerable Rei. There's the appeal of cracking through a tough outer shell into the gooey insides alongside the draw that comes with the idea of healing and helping another human being, teaching her how lurrrvve and all that.
Basically she's the waifu equivalent of an apex predator.
