It looks like the new single is called
Gold Finger Girl and it's produced by Kenichi Asai of BLANKEY JET CITY.
CDJapan has a pages up for a
limited edition CD+DVD and a
regular CD Only but it looks like the release has been pushed back as both pages have it listed as "release cancelled."
They probably want to give Chiaki more time to properly promote
Kanosei Girl before releasing another single.
And as a sidenote,
Kanosei Girl was given an external bonus of trading cards. They're all gone already at CDJ and they must have been a last minute addition as I only noticed it yesterday. I ordered my copies from YesAsia so I hope I still get them.
