Aya learned to play the piano when she was 4 years old. In junior high school, she began singing live. Influenced by punk rock, she also learned how to play the guitar.
In 2005, Aya released her two mini-albums "Constellation" and "Rock On" from the independent record label Weed Records.
Aya's singing career was mainly active in Osaka, where she garnered positive results. Her voice was so full of force that it was part of her reputation. She made appearances in music and fashion magazines, which caught people's attention.
In 2006, Aya signed on with Giza Studio and released her first major label single "Communication Break" on March 15th. On April 12th, her second single "Pierrot" was released. The song was respectively written and composed by B'z members Koshi Inaba and Tak Matsumoto, although the lyrics in Aya'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). The single reached 9th place on the Oricon charts. Her third single "Mou Kimidake-wo Hanashitari-wa Shinai" peaked at the 11th place, and her first full album "Secret Code" debuted at 5th place. In order to promote Secret Code's release, Aya held two mini-concerts. One was as "Black Kamiki" and was performed at Tower Records in Shibuya. The other (later on the same day), was as "White Aya" and was performed at HMV in Shibuya. Entrance was free, provided that you had purchased Secret Code at the corresponding store.
