Character Description: Cain
Cain was a young Bounto boy that Koga once cared for. When Koga was fighting, he was reminded of Cain and the grotesque details of his death.
Years ago, Cain was entrusted to Koga for caring, and Koga raised Cain to be a Bounto. Cain entered Koga's home as a spoiled brat, but grew to be a disciplined young man. Koga treated Cain with love, but his fatal mistake was to give Cain a doll too early. Cain summoned his doll-but however, he was unable to control it, and he turned to dust before Koga's eyes.
Cain represents guilt and sorrow to Koga, as Cain died at such a young age and Koga was unable to prevent it.
