I've been to the concert, and when watching, in no way was I reminded of AT05. I thought that the costumes for Evolution/Unite did look a lot like those used at AT05, but the dance, the theme, etc. is completely different.
Ayu's in love with sexy costumes, it seems. No problem with that with fans I'm sure!!
And I HOPE Ayu keeps the catwalk thing in the future. It's awesome!!! She gets to be close to her audience, and the audience goes crazy!!
