It's my understanding that the dev aims more for "gyaru" than "bimbo" in this area - she might end up deprioritizing school and failing a test or two as a result, but she's never going to be
stupid.
But I agree; during my runs, she's going to be as smart as can be, even as she becomes more, ah,
open to new experiences. The idea of the country's number one student being someone you'd expect to be a shallow airhead based on her appearance is one that's extremely amusing to me.
I do wonder how far we'll reasonably be able to take that dichotomy, though. Take the interests room, for instance; Aura only has a limited amount of time in her life, so to pick up an interest in following fashion, she has to set aside a series she previously enjoyed. I'm assuming that the hours in the day and space in her brain will continue to be a limiting factors in other aspects of her corruption - and becoming a proper gyaru involves a lot of things that don't involve studying for tests.
Well, even if I have to give up on that particular goal, I'll still be able to make her a cold-hearted, self-centered "hero" who pursues hedonism above all else, so I'm looking forward to her future self either way
