[ElProximo]

Noirin is something like a mannequin - all the attractive shapes and features are in the right places but she has no actual sex appeal. No 'spark', no magnetism.
Obviously her borderline sociopath 'personality' then makes her appearance seem ugly.

Hira has gorgeous features but she has zest and super-cuteness and is kind hearted and doesn't know how to involve herself in drama.
Hira for the win.
