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.
They say that a lion will use all 
of its strength to hunt a rabbit.
يُقال أنّ الأسد يستهلك كلّ قوّته لاصطياد أرنب
Es heißt ja, dass ein Löwe auch bis zum Äußersten
geht, bis er einen ersten Hasen gefangen hat.
Il faut donner le meilleur de soi
en toutes circonstances.
Si dice che un leone darebbe
tutto se stesso per catturare un coniglio.
Dizem que um leão usa toda sua
forma mesmo contra um coelho.
Как гласит поговорка: «Лев не жалеет сил,
даже когда охотится на зайца».
