Four years had passed since Sagan's called a truce with the D2s. Music was still taboo throughout the world, and melodies ceased to be heard. Somewhere in America, which was now a wasteland, a little boy who grew up not knowing what music is hears the melody from a piano. The one playing it is a young man with black hair named Takt. And then, a deformed creature known as a D2 and a girl named Destiny, who is armed with a sword, appear as though they were lured in by the melody.

D2s awakening. Takt's hometown being attacked, and Cosette's death. This was all a part of Sagan's plan. Shindler wants to get rid of all those inferior to him in this desolate world. After learning the truth about Cosette's death, Takt charges at Shindler in a blind rage. But Takt is injured by Hell. As she witnesses Takt injured and bleeding, Destiny feels some emotions welling up inside of her that she's never felt before...
