Lily Chou-Chou (リリイ・シュシュ) is a fictional artist created for the film All About Lily Chou-Chou, with vocals by Salyu. Though saturated with her presence, by way of the soundtrack and movie plot, she remains almost entirely unseen throughout the film. Her persona and popularity are based on the massively popular Chinese singer 王菲 (Faye Wong). Her album, Breathe (Kokyuu), came in the form of the film's OST, with music/production by Takeshi Kobayashi, and singing performed by Salyu.
