The entire group officially graduated from Hello! Project on March 31, 2009, along with the rest of the Elder Club. After their graduation, they collaborated with other Japanese punk-rock groups for several limited-release indie singles, and released their 4th album Melon's Not Dead. Two days after the album release and just after their 10-year anniversary, the group announced that they would disband following their final tour activities in May 2010. The group performed together for the last time on May 3, at Nakano Sun Plaza.
