Instead of one, six new members won the audition, resulting in an eight-member (Dream) group with the debut single "Music is My Thing". On March 2004, Risa Ai left to pursue a solo career. They became a 7-member group as performed this way until 2007. During this time, the band's name changed from dream to DRM. 
In August 2008, Yu Hasebe left the group to pursue a solo career, leaving Kana Tachibana behind as the only original member of dream. Afterward, DRM became Dream again. 
In August 2010, Dream released their official major re-debut single, "My Way: Ulala" on the Rhythm Zone label. On November 24, 2010, Dream released their first album as a six-member group, titled "Hands Up!" on the Rhythm Zone label.
