Fake how? She acts like herself.. I mean, if she's told to be nice, fun and bubbly on stage, that isn't "fake". She's being herself, but her happy self. If she's asked to do her cute anime voice, that is her cute anime voice. IMO, she could be called fake/unnatural if she was lip synching to a voice that isn't hers, or starts slapping people around pretending that it's real. Like in GAME, she acts all dominant. Now acting isn't fake. It's acting. It would be fake if she acted dominant backstage and pretended that it's real. xP
I find it so annoying when someone says that she's fake. Ayu = ayu. She would only be fake if in real life she's a very mean and agressive person, while she pretends to be nice when the camera's on. Which probably isn't the case.
Also, talent doesn't "become" unnatural. You have talent or you don't. It doesn't disappear or become fake. If they mean that her voice becomes too old and she hasn't to lyp synch (which isn't the case, IMO) it's still her natural voice and talent. Even if she was a man or was freaking ugly and had plastic surgery it's still not fake in my book, because that's how she is now and she is who she is. It would be fake if her nose wasn't really on but could be taken off or whatever. Heck, even Michael Jackson isn't really fake. He is who he is, and made that choice to look like that.
Sure, she's avex's product. Avex wants her to cry during ballads so that they sell. So she acts crying. Is that fake? No.. It's acted. If she says that it's real, she would be lying but IMO it would still not be fake.. Just acted. It's kind of different to say "her crying is fake" and "her crying is acted". The word fake would imply for me that she doesn't feel the song, which she does.. She wrote those lyrics -- the songs are her. If she acts her crying, that doesn't mean that she doesn't feel the emotion. She feels the music. ^-^ And her music isn't fake.
Edit: Lol, my rant became longer than I had thought. I cleaned it up a bit.
