I loved the packaging of the album and the shoot
I like how the package make it looks like a book, it kinda fits the idea of WALK OF MY LIFE, like a register of her journey. And iirc they announced a special booklet for the CD+DVD and +BR version, and indeed they are, the term used was not "photobook"
As for energy, I didn't feel lack of energy from Kuu in the live, but she wasn't exploding like during ECSTASY @ a-nation either lol And too much black is a matter of taste, I am loving all her outfits this era
