I can't help but think Aya types are in a state of ego-death by default, with that look that passes judgment on you without really considering herself at all.
Are Ayas really egotistical? Their face permanently /looks/ smug, and they instinctively say "Ooh, X, X...", but is that arrogance, or natural behavior?
Personally, I love them. Alices are arrogant shits, not Aya.
