Ralen said: I'm not familiar with either of the other two series. Are these "Bad girls"?
Mitsuko was mostly just stuck up and arrogant, but actually helped the heroes when it mattered. Ayase was mostly just 'ew neeeerdy' regarding one of her friends hobbies, but otherwise not really 'bad' at all. There is a vague appearance similarity I suppose, but even that's a stretch as Mitsuko's hair was properly black not any shade of blue.
Funny thing is, the spoiled rich "ojou-sama", Kongou Mitsuko, is actually the nicest of these three girls.
Even at her worst, Mitsuko isn't "b*tchy" so much as she's been raised to believe that she has to act elegant and high-class with everyone in order to impress them. That works when you are dealing with other rich people, but she later realizes it's not so effective for making normal friends (which is what she really wants). Once she realizes that, she mellows out a lot (even mentally apologizing to the people who've had to put up with her previous behavior), and she is a dedicated friend who will gladly risk her life for you and for innocents in general.
In contrast, Ayase acts nice and pure, but is an almost yandere-esque bisexual (she seems to have feelings of lust for both Kirino and Kyousuke) who later develops a closet fetish for BDSM (or at least for handcuffs). Doesn't help she is quick to deny anything wrong with herself and shift the blame onto others while judging their hobbies. Did I mention the kicking? Cuz' outside of a comedy like Oreimo, kicking someone in the head so hard that they spiral through the air like that will break their necks if not break their skulls.
Do we even need to discuss Asakura? This is someone who decided to kill the love interest of a young girl, who unwittingly possesses god-like powers that let her subconciously rewrite reality, just to see what would happen next. The one proclaiming she's not a "bad girl" is literally the worst of the bunch.
