During their time active, they released two singles via Hello! Project compilations, a cover song called "Kimi ga Irku Daki de" in July 2009 and an original song in December 2009 called "Pira! Otome no Negai". The unit continued to remain active throughout 2010, performing at various Hello! Project concerts and doing a variety skit for a Hello! Magazine DVD in 2010. Their last performance as an active group was in January 2011 during a winter Hello! Project tour. Following the conclusion of the tour near the end of the month, six of the seven revival units, except for High-King, all ceased activities, unofficially confirming their disbandment.
In January 2013, Petitmoni V briefly reunited for Hello! Project's 15th anniversary tour, performing alongside Hitomi Yoshizawa, a former second generation member of Petitmoni.
