Wind Wave's (Kamen Rider W's fictional radio station) DJ HurryKenn has posted on his Twitter account that are gathering various girls with motifs from various Kamen Rider shows and turn it into an idol group (Kinda like AKB48) called Kamen Rider GIRLS!
Aside from singing, they will also dance, and occasionally, fight. A CD is planned to be released.

Author's note: Now, I am starting to wonder, what happened to Rider Chips, the rock band responsible in making various theme songs in Kamen Rider shows? The last time I heard them was in Kamen Rider Kabuto...
About the idea, it reminded me of the Queen and Elizabeth unit back in Kamen Rider W and the duet by the girls in Kamen Rider Kiva. Hope this would be a blast!
