Sugar (슈가) is a Korean girl group. Their 2003 singles "TAKE IT SHAKE IT" and "real identity" were the opening and ending theme songs respectively for season 1 of the highly popular anime "Kaleido Star". However, they had mediocre success in the South Korean market. Their last album has seen them go through an image and style change, as members have been changed. The album had less "cute pop" material and instead focused on rock songs and midtempo ballads. However, their albums did not have high sales. Since then, Soo Jin has left the group, and Ahyoomee has gone on to have a solo career. On December 20, 2006, KBS World Radio announced that the group had officially disbanded.
