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.

After separating from Lenny and Titan, Takt and crew continue their journey under the blazing sun. During their trip, they end up fighting some D2s and end up bringing a train on the transcontinental railroad to a sudden stop. They then see a Musicart in white armor and a Musicart with a bewitching smile. The man accompanying the two Musicarts is named Shindler and calls himself the Top Conductor of the New York Symphonica.

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...

Lenny remembers his own past. Lenny recalls someone very dear to him. Everything leading up to today was so that he could do everything he could to do what he had to do. Lenny heads to the meeting point along with Titan so they can tell Takt and Destiny everything. But someone rather unexpected was waiting for them.

Destiny is terribly cruel. But no matter how much misfortune the gods torment me with, I will face my destiny. Because of that, I fought, and I fought, and I fought some more... And then, I finally found my answer. There truly was joy beyond the pain. Now, it is time for the performance to begin. I shall now wring destiny's neck. "From a certain man's memoirs"
