Cosette transformed into the Musicart named Destiny. Destiny proclaims that her mission is to eliminate the D2s. Destiny bestows a conductor's baton upon Takt, and he uses his Conductor powers for the first time. And then, they are confronted by two individuals: Lenny and Titan. They are an official Conductor and Musicart from the New York Symphonica, which was the strategic headquarters to fight the D2s.

Takt and crew stop by a certain town. All of the young people had fled the town, leaving only the elderly. The residents happen to ask Anna and Destiny for help. Meanwhile, Takt wandered around town on his own and happens to hear a melody quietly resonating from an old bar. It was definitely the sound of music.

Anna and Destiny happen to see a town destroyed during their travels. D2s are awakening everywhere and attacking various towns and people, reverting the world back to four years ago, before Sagan's Declaration. As the threat from the D2s grew, Takt was obsessing over something. With a blank staff notation in front of him, Takt plays an imaginary keyboard as he desperately tries to create something.

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...
