yes, they have tried to make a girlband concept using popular Adult Idol on 7th April 2009. but the result was a big flop and not everyone like it (because what they do best is doing sex, not singing and writing music). I think this group has been disbanded years ago but I don't know when... or according to them, this project is on halt until further notice (finding the right time and material to make another music) but personally I doubt that they are gonna continue this project again. here's the complete list of all the members (there are actually 25 members!) :
Ando Aika
Aoi Sora
Asami Yuma
Fujiura Megu
Hatsune Minori
Kasumi Kaho
Kasumi Risa
Kawamura Ena
Kawamura Rika
Kirihara Erika
Kizaki Jessica
