Tập 83: Koga nhớ lại việc huấn luyện Cain, người đã gây ra một vụ tai nạn thương tâm do con búp bê mất kiểm soát, khiến anh vẫn còn day dứt.

83

As Koga tells Dalk to finish Ichigo off, he is reminded of Cain, a young Bount he once mentored. In a flashback, Koga remembers when he first met Cain, and taught him how to summon his doll and live with another Bount. However, the doll Cain created was too powerful for him to control and destroyed him, an incident Koga continues to regret. (Source: Wikipedia) The Bount arc: (20/28)
