Cain

(seiyū: Takayuki Fujimoto, voice actor: TBA) is a young male Bount whom Jin Kariya had left in Koga's care many years ago. He has cropped reddish-brown hair and blue eyes, and often seen with a similar expression to Ichigo Kurosaki's. He states that before he came to live with Koga, he had a difficult life. He died after summoning his doll, and coaxing it to use its powers before it had time to rest, resulting in the doll killing him. this death effected Koga profoundly, causing him to dislike killing the young.
