I wasn't here around the time the cover was first shown and the first thing I noticed when I went to Ayu's site was how the photo seemed strange, as if the hand was simply removed to not distract from Ayu's face. I thought it could in no way be hidden behind the 'pillar' because of how clearly visible it was in the reflection, however, after taking a closer look, it looks like that was the case indeed and it's simply covered due to the angle the photo was taken at.
Sorry about the repetition of topics.
