Zoku V-u-den is a revival unit under the Hello! Project umbrella, featuring vocalists Sayumi Michishige, Junjun, and Risako Sugaya. The group released their signature track "ONLY YOU" as a cover on a Hello! Project compilation in July 2009, blending pop-dance sensibilities with the polished production characteristic of the Hello! Project catalog. The unit maintained an active touring presence throughout 2010 and 2011, performing regularly at Hello! Project events and contributing to the label's distinctive J-pop dance sound.
Following lineup changes and the departure of Junjun in late 2010, Michishige and Sugaya continued as a duo before the unit entered hiatus after the winter 2011 tour. Zoku V-u-den briefly reunited in January 2013 to commemorate Hello! Project's 15th anniversary, performing alongside original V-u-den member Rika Ishikawa and reinforcing their legacy within the Hello! Project's dance-pop ecosystem.
