A manga adaptation by Rio Fujimi recounting Kusumi's rise to stardom was serialized in "Ciao", titled "Miracle Revolution: Koharu Kusumi's Story". Preferring the freedom she had working on her solo projects, Kusumi decided to pursue a solo career after "Kirarin Revolution" ended, mainly in modeling as well as other paths in entertainment, including comedy. On September 19, 2009, Tsunku announced that Kusumi would leave Morning Musume and Hello! Project on December 6, at the final performance of Morning Musume's 2009 fall tour, "Nine Smile". Roughly 4,000 fans attended the graduation concert.
