Ai Coleman grew up in Hole under his grandfather's care, though the old man largely neglected him. It's a rough start that left Ai withdrawn and isolated, but he was smart enough to recognize his boredom for what it was—a problem that needed solving. He found refuge in books, particularly one about sorcerers written by Dr. Kasukabe, which sparked something in him.
His hometown's reputation didn't help. Sorcerers regularly showed up in Hole to conduct experiments on humans, which Ai despised. Yet he couldn't help being fascinated by them too—by what they could do, by the power they wielded. That contradiction stuck with him. Instead of letting resentment fester, Ai decided he'd find a way to become a magic user himself. If sorcerers could wield that kind of power, so could he.
