On February 23rd, 2007, guitarist Iori and drummer Matoi left the band.

On April 5th, KISAKI announced that he will be retiring, and that Iori and Matoi have returned to the band, but the band will be "sealing." He followed up on the announcement on a live radio show on April 8th, where the band's first and last fan trip was revealed, as well as the final event tour and final oneman tour. KISAKI officially retired from the active visual kei scene on August 31, 2007 but will continue to run his label and produce.
