I went to Shibuya today and of course I had a quick look at Tower Records while I was there (love visiting Tower Records), so to shut up whoever says the album isn't on the stores or isn't being displayed here it is:
On the first floor (the floor with the new releases):
And also on the daily top 20 shelf:
And on her section on the j-pop floor:
Whoever says the album isn't for sale for sure didn't even try searching...
And of course I also saw the awesome huge billboard in front of the station, so cool, you can even see it from the train arriving and leaving the station
