A dragon of heaven, Aoki is a mild-mannered copy editor with a wife and child, who is also a wind magician. In the TV series, upon discovering that the battle between the Seals and Angels is at hand, he secretly divorces his wife Shimako in order to spare her grief should he be killed. Although Aoki is very powerful, he rarely sees any action in battle for much of the first half of the story as he is quite busy editing manuscripts. He is a wind master, with the ability to conjure and control wind currents. This is his family's gift; his nephew Saiki Daisuke has the same ability, though he isn't as strong.
