What Ayu album had biggest/most dramatic step up compared to the previous for you?

[AyuGAME]

my story to (miss)understood

I think (miss)understood really suprising me and that album shows Ayu sing the song that she like not because what the trend is.

But it's like double axe because I remember many persons not really liking the style of it. She is losing fans because of this release. Pretty much it's a sweetbox cover album.
