This 10th Anniversary is really special and I think that Kuu is enjoying it very much. I agree she's at a peak, a peak of satisfaction and joy. These photoshoots, her live concerts and her music wouldn't be that good if she wasn't happy. She just shines in every way!
Love the pics from Brazil, especially the ones in nature!
EDIT:
I'VE GOT MY COPY OF BRAZIL RIGHT NOW XD
I'm so happy, almost every side of the 160 pages is gorgeous!
