It's not just beauty, in a way you could say it's personality too.

In Kalawarner's case, she's simply a villain with an objective who happens to look down on Issei and co due to either being easily killed off originally or based on the knowledge that they were basically the sheltered children who grew up in psuedo-peace time.

Asia on the other hand is the pure and innocent ditzy girl with not much common sense around her. While that in itself is not bad, over the course of the series as Asia develops more as a character, I've just begun to find he personality and characteristics annoying. While I don't hate her, I don't like her as much as I used to.

This goes double for anime only viewers as the anime doesn't really develop her at all as a character so it's easier to dislike her.
