On October 2, 2009 Kitade announced she would begin working on a duo project with Japanese guitarist, Taizo, called Loveless. On October 11 it was announced on Loveless's official site that Kitade's contract with Sony Music Japan has come to an end. Throughout 2010, Kitade toured Tokyo, Japan, promoting Loveless.
