Well it's been speculated, so no surprise here. I'm not crazy about her visual aspect. So they kind of did a favour for Max but totally missed the mark for Ayu *shrug* Like she's pretty and all, but she's a different kind of pretty than Ayu. Ayu has this doll-like face. This girl, doesn't really. Although she does sound a bit like early days Ayu. So i can see the similarity there.
I mean she's definitely less robot-like in here more ballad-y songs. BTW this one is very Rainbow'esque, with that whole chasing after your "twin" concept..
