GHOST CONCERT : missing Songs

In the year 2045, music as humanity once knew it has been entirely outlawed. The act of playing instruments and composing melodies is no longer a human endeavor; instead, an artificial application known as "MiucS" controls all sound production. Society has adapted to this silent existence, accepting the absolute prohibition on organic musical expression without question. Amid this heavily regulated world, a high school student named Seria is spending an ordinary day out with her friends when she encounters something impossible: the unmistakable sound of a human voice singing. Following the forbidden melody, she discovers its source—a solitary ghost known as a "Great Ghost," an enigmatic entity that has crossed over from beyond the boundaries of their reality. This spectral figure represents everything the authorities have sought to erase. Seria’s chance discovery forces her into an agonizing dilemma. She must choose between maintaining the safety of silence or risking absolutely everything to challenge the ban. By deciding to protect the Great Ghost and embrace the forgotten art of song, she sets herself on a dangerous path to restore music to a world that has long since forgotten how to sing.
