KK did this hard worker / fighter look before for her own 10th anniversary in 2010.
While this is a shot from the MV she could have picked the other 2 looks but she picked this one, cause it represents the song title better. She did say before that she's still criticized by people in Japan and this look could be a reference to her still fighting to be herself. I love the new picture. I wish we got it in HQ. It's interesting that she went from her hands intertwined for re(LIVE) to unlocked on this picture. I really wonder if there's a meaning behind her doing this.
