Adam Kadmon (アダム, Adamu) is a demon in the series.
The original man in the teachings of Kabbalah, untainted by earthly matter. He stands in contrast to the Adam of Eden, who was made from earthly clay. He was the perfect prototype man made by God, with the Kabbalists taking this concept to describe the divine symbolism of the human body. In later teachings Adam Kadmon came about to personify the Messiah, with Adam Beliyya'al' being his contrast as the devil. He is symbolized by the Sefirot, which are the Ten Circles of Creation in the Kabbalah.
