I'm a little late writing about these girls, but In the midst of all of the idol groups that seem to debuting lately, we have another added to the team!
Meet Panache!, a three girl idol group made up of three popular cosplayers. The girls's mission is to spread Japanese cosplayers' culture to other countries, (which is actually, already really popular overseas). These girls (from left to right Kuroneko, Enako, and Itsuki Akira) will be making their CD debut with SONY tomorrow, October 24, with their single Kirameki Miraizu. The b-side will be a cover of Happy Synthesizer, an extremely popular vocaloid song by Easy Pop. Previews of the song's can be heard here
