What do you think are the meaning of Ayu's 3 new PV's?

[waterballoon]

1) I don't think this actually means anything... probably the change in color looks nice or something. XD

2) This, to me, is showing that modern idols are all too manufactured/fake/unoriginal. Like they're all robots now and are products rather than idols/human.

3) For aesthetic purposes, I suppose.

4) Ha, nice point you brought up! I actually forgot about this one... well, I think it's at least like Ayu is telling us that at the end of the day, she's still like an 80/90's idol. She's still natural, original, cute, adorable, innocent and what have you. I'm sure she knows how direct and 'rude' Sparkle is. Nice saving-yourself method haha.
