It all began ten years ago. D2s attacking Boston, a blood-soaked concert hall: The incident known as the Boston Tragedy. The conductor who lost his life in that tragedy was none other than Kenji Asahina, Takt's father. After losing his father, the boy decides to devote himself to playing the piano and he lets his rage play through his melodies. The one who took care of him was a girl named Cosette, who looked just like Destiny.
Besides, there are no pianos 
left outside anymore.
فضلاً عن ذلك، لم يبقَ أي بيانو في الخارج بعد الآن
Außerdem gibt es da draußen
keine Klaviere mehr.
Et il n’y a presque plus de pianos,
dehors.
Senza contare che
non ci sono più pianoforti in giro.
Sem contar que nem
deve ter pianos lá fora.
Да и где мы снаружи рояль найдём?
