In 2006, Kamiki signed on with Giza Studio and released her first major label single "Communication Break" on March 15.
The song was respectively written and composed by B'z members Koshi Inaba and Tak Matsumoto, although the lyrics in Kamiki's version were slightly modified.
It was released on the same day as the B'z single "ゆるぎないものひとつ" (Yuruginaimono Hitotsu), which contained "Pierrot" as its 2nd Beat (B-side).
She makes an appearance as an in-game character in the 2008 visual novel 428: Shibuya Scramble (later released internationally in 2018).
by Kamiki Aya and TAKUYA UNREAL and V/S singles were sold during live concerts; the title songs can be downloaded via iTunes.
