takt op.Destiny

Four years had passed since Sagans 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.

Cosette transformed into the Musicart named Destiny. Destiny proclaims that her mission is to eliminate the D2s. Destiny bestows a conductors 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.

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 Sagans 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.

Takt and crew finally reach their destination of New York. They reunite with Charlotte, Annas older sister, who works for the Symphonicas technological development department. Charlotte begins to examine Destiny. Who is an incomplete Musicart. But then, Anna realizes something is wrong with Takt. The mark on Takts right arm starts to spread to the rest of his body, and...

A giant Black Night Siderite starts to stir as Sagan hums a certain melody. The Black Night Siderite that grows as big as a tree starts to swallow up the New York Symphonica. Sagan has finally made his move to make his ambitions come true. As Takt and Destiny witness this eerie spectacle, they find out that Anna and Charlotte are still inside the Symphonica.
