All About Lily Chou-Chou (2001)

Life isn't easy for a group of high school kids growing up absurd in Japan's pervasive pop/cyber culture. As they negotiate teen badlands- school bullies, parents from another planet, lurid snapshots of sex and death- these everyday rebels without a cause seek sanctuary, even salvation, through pop star savior Lily Chou-Chou, embracing her sad, dreamy songs and sharing their fears and secrets in Lilyholic chat rooms. Immersed in the speed of everyday troubles, their lives inevitably climax in a fatal collision between real and virtual identities, a final logging-off from innocence.
