GHOST CONCERT : missing Songs - S01

In the year 2045, singing is banned, and all music is generated by an app called MiucS-no human performs or creates it anymore. One day, while out with friends, a girl named Seria Aiba hears something impossible: a human voice singing. Chasing the sound, she meets a ghost-not just any spirit, but a "Great Ghost," an otherworldly being. As Seria gets pulled deeper into encounters with Great Ghosts, the psychic group TERA, and an eerie song called the "Possession Requiem," she uncovers a hidden side of a world that has erased human music. This is the story of how Seria's life starts to change-and how she begins her own journey toward becoming a ghost.
