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. (Source: Crunchyroll)
