The year is 2045, in a world where songs have been banned. Instead of humans playing instruments and creating music, a music app titled "MiucS" is in charge of these things. High school student Seria goes out with her friends one day, but she happens to hear someone singing, which is supposed to be prohibited. What she finds is a lone ghost, a "Great Ghost" who has appeared from outside this world. Now Seria must decide whether to stay silent or risk everything to bring music back to the world.
