Takt op.Destiny

Four years have passed since Sagan's called a truce with the D2s; music is taboo throughout the world; melodies ceased to be heard.

It began ten years ago; the D2s attacking Boston, a blood-soaked concert hall: the incident became known as the Boston Tragedy.

Cosette transforms into the Musicart named Destiny; Destiny proclaims that her mission is to eliminate the D2s; she bestows a conductor's baton upon Takt, and he uses his Conductor powers for the first time.

Takt and Destiny learn how to fight properly from Lenny and Titan as they continue to make their way to New York.

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.

Takt and crew stop by a certain town; the residents ask Anna and Destiny for help; Takt wandered around town on his own and happens to hear a melody quietly resonating from an old bar.
