Two girls meet in Mars's AI-saturated future and decide to make music together, which sounds like setup but the show means it, their songs are actual catchy hooks you'll replay, not background texture. The first half watches them learn the industry will grind them down before they even start, and Watanabe's direction makes every setback land with real weight. The second half loses the plot entirely, characters become interchangeable, and you can feel the writers scrambling. Watch it for the first twelve episodes and the soundtrack that will stay with you longer than the story does.

Two girls meet on Mars in a future where artificial intelligence dominates the music industry. Carole works odd jobs in the sprawling city of Alba, chasing a dream that feels impossible in a world where algorithms compose most songs. Tuesday comes from a wealthy family in the provincial Herschel City, where nobody understands her wish to make music, so she runs away with her acoustic guitar. When their paths cross, something clicks. They decide to perform together, hoping to pour their feelings into their songs. But the odds are stacked against them, since AI singers rule the charts. What starts as a small ripple may grow into something far bigger for the duo, if hard work and luck are on their side.
