As usual, I have a certain affinity for arrogant, aloof, and sophisticated/intelligent female characters.
Of course, she did say some fucked up stuff to Anaru, which I felt was kinda overboard, but I think she's made up for that in recent episodes.
Everyone in this show seems to have found a different way to cope with what happened. Her way was just to become detatched and succeed in other aspects. Yukitasu's kinda like that too.
