The year is 2045. Singing is forbidden, and an AI system called MiucS creates music in place of people. Seria Aiba, a high school girl who can see spirits, lives quietly under these rules—until one day, she hears a real human voice singing. Following the song, Seria discovers the source: a ghost. Now Seria must decide whether to stay silent or risk everything to bring music back to the world.
