Kamen Rider Girls

Kamen Rider Girls (仮面ライダーGIRLS, Kamen Raidā Gāruzu) is an idol group developed by Avex Trax and Ishimori Productions to commemorate the Kamen Rider Series' 40th anniversary in 2011.

The group's debut single will be "Koi no Rider Kick" (恋のライダーキック, Koi no Raidā Kikku, "Love's Rider Kick"), which will be accompanied by the song "Heart no Henshin Belt" (♡（ハート）の変身ベルト, Hāto no Henshin Beruto?, "The Heart's Transformation Belt"). The group's debut songs were played on the DJ HURRY KENN Ride the Groove Internet radio program, the successor to the Wind Wave radio programs from the Kamen Rider W series.
