I think the thing about CREA is complicated since she has composed since Will (notably in
November 2008 for a song in the running to become the A-side with Rule) but the song did not make it in the end. It's assumed that Sparkle was the winner in the end and Ayu's composition as CREA just never got mentioned again.
Kazuhito Kikuchi also has always given Ayu songs nearly annually to use as demos but she only chose one this year after the last one was 14 years ago.
