Four years had passed since Sagan's 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.
I feel like I'm going to be
 in the best mood today.
أشعر وكأنّني سأكون بأفضل مزاج اليوم
Ich kann den Tag heute
wohl richtig genießen.
Hoy voy a tener un buen día.
Hoy voy a tener un buen día.
Je sens que je vais passer
une excellente journée.
Credo che oggi sarò di ottimo umore.
Sinto que passarei o dia de ótimo humor.
Давненько у меня такого
 хорошего настроения не было.
