Takt and Destiny learn how to fight properly from Lenny and Titan as they continue to make their way to New York. However, Takt and Destiny still have a hard time being in sync. They then coincidentally run into Lenny's old buddy Jonathan. Jonathan then leads them around his home, Las Vegas.

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...
