We can't be sure for certain on whether she has had surgery or not, even something as simple as eye-enhancement surgery. I believe she has, and I'm an Ayu fan who does believe in it, so it's not always just the Ayu-haters who say it

But really, does that make her a different person inside? I don't think so. Whether she has had or not, it doesn't change the fact that she's an extremely talented and creative person; and I'll always support her for that.
Plastic surgery among celebrities is so common, so I've never ruled out that she hadn't had it done. I'm not saying she's had
a lot done, even just small touch-ups is counted.
