He fought alongside Blaid in the Keyblade Wars and slew many brothers and sisters of the Keyblade in his name however he was brought to near death in one battle which his level of healing wouldn't save him and so Blaid made an offer: if Toru were to injest his blood then it would cause Toru's dormant Black Blood to awaken, allowing him to heal quickly however in doing so he lost his eyesight and so allowed Blaid to teach him the basics of the Darkness so that he could enhance his sound and smell to give himself a bleary picture of the world, he also wore special glasses to enhance his damaged sight.
