Ai Coleman used to be a quiet and withdrawn boy from Hole. He was raised by his grandfather, and was neglected by him. But Ai was a very intelligent kid, and the absence of stimulation in his life left him quite bored and depressed. He spent his time reading books. Or at least one about sorcerers written by Dr. Kasukabe. Ai hated living in Hole, and he hated that sorcerers came there to experiment on humans, but he was also fascinated by them. And so, Ai decided he'd find a way to become a magic user.
