Sayane was a struggling, down on her luck J-Pop idol who was crushed on stage. After dying, she wakes up in a dangerous realm where music was once the source of magic but is now long forgotten.

A tyrannical empire wiped all music from history and silenced the realm so that no one could ever oppose them. Small bands of resistance fighters and revolutionaries hide in underground districts and taverns. That is where Sayane winds up.

There, her love of music and people propel her into conflict where she finds creative freedom, fans, and maybe even purpose.
