Ai Coleman is a human and Hole resident who resents his life and wishes to become a Magic User. He is the original personality/basis of Aikawa, Kai, and Kaiman. Ai is not capable of fighting nor producing smoke to activate any sort of magic, therefore, if he inhales or ingests Black Powder or any kind of magic-enhancing drugs, he will not be affected nor show any side effects from it. Ai is a young and very frail boy who can barely defend himself and often takes the beating he receives.
