Lmao money milking. This is probably the less money milking she has done since she became popular. I mean, same covers for all versions? Same content for the dvd/bluray editions? No fc edition with some special bonus concert like the ones she used to give us? This release is different and it's indeed more focused on her two sides, the strong kuu and the emotional kuu. Like corvina said, it's like a more polished work of what they did with Universe and third universe. Maybe even to compensate all the disappointment that was that "double" album.
( I admit when I heard about this two album thing my brain automatically painted a best + original album haha it was even worse when I saw the promo pic it reminded me of BoA's best & usa. I really got scared for a second
