The Saint-Saëns' Assassination was tragedy in the musical world. It meant a loss, especially for the fact that Persephone and Nyx, the girls in the family were famous music prodigies... As a prophecy revolving the world being under control of a mysterious group is spread, will anybody be willing to sacrifice themselves to save this from happening, even if the prophecy hints that the now dead Saint-Saëns will be the ones to save the day and that two people will be killed? P. S. I suggest listening to the songs written when it is written that they're playing the song and follow the book, though it's your own preference.
