When orphan Carole meets runaway Tuesday, an uptown girl who wants nothing more than to make music, it's as if they were fated to find each other. With their shared dream, the duo charges headfirst into the
world of entertainment--but on colonized Mars, with a consumer base accustomed to "perfect" A.I.-produced songs, is there any hope their organic sound and heartfelt lyrics will reach their audience?

In a story based on the hit anime directed by Shinichiro Watanabe (Cowboy Bebop, Samurai Champloo, Kids on the Slope), two girls from different worlds connect through a love of music and a desire to make it big on Mars.
