GHOST CONCERT : missing Songs - S01

In the year 2045, singing has been forbidden. Music is no longer made or performed by humans; instead, a music app called MiucS produces every song for them. One day, a girl named Seria Aiba is out with her friends when she hears a human singing voice, something that should not exist anymore. Following the sound, she meets a mysterious presence: a ghost. What appears before her is not an ordinary spirit, but a being from beyond this world known as a Great Ghost. As Seria is drawn into encounters with Great Ghosts, the psychic organization TERA, and a strange song called the Possession Requiem, she finds herself stepping into a hidden side of a world that has erased human music. This is the story of how Seria's life begins to change, and the path that leads her toward becoming a ghost herself.
