Adam Kadmon

Adam Kadmon is the only success in God's experiment to create a Seraphita. The Six Winged being who first "gave birth" to Alexiel and Rosiel, thus dividing his power between them. (In truth God created them from the body of Adam Kadmon) And by the end of the story the only physical thing left of him is his Head. (Body made into Alexiel and Rosiel, his "evil" Left Eye was planted and the Tree of Life grew from it.) On earth, he appers as an afterimage, asking Setsuna to free him before God realizes his transgression. Setsuna does free him, but this is an imposter, who only cares for destruction.
