Kamen Rider Girls (仮面ライダーGIRLS, Kamen Raidā Gāruzu), stylized as KRGS on some occasions, is a Japanese idol group that was formed in 2011 by Avex and Ishimori Productions to commemorate the Kamen Rider 40th Anniversary.[1] Each member had represented one protagonist each of the franchise by donning their represented hero's transformation belt, though this practice was scrapped in 2016 to better represent the franchise as a whole and to avoid licensing issues.[2]
