^No, I think most of her fans are attracted to her because of her music/voice. As for role-model-wise, I think the girls see her as "erotic-cool," something really different from what they're usually exposed to.
Face it, no one can sell over a million albums without talent. Or...is Ku just a bluff who happened to have sold heaps load of CDs with her "package" alone
? I honestly do not think that they bought the albums just to stare at the sexy booklets. I mean, come on, they show really nothing that a pervert would have wanted to see.
And to answer the original question, I say no. Ayu's sales haven't been too "ideal" compared to those from the apex of her career. Unless this single is miraculously a PERFECT piece, then no.
