@happiholic★: Kingdom was not sure to sell, scandals don't sells on Japan.
The scandal affected the second week of Kingdom, with all the lives, CMs, magazines, radio, everything being cancelled. There is a huge drop between the 1st and 2nd week (421k to 84k).
And Kingdom was the album with the most promotion (for a studio album), a lot of performances was on her schedule. (if I'm not wrong)
