The current human incarnation of the Organic Angel Alexiel. Though dormant inside him Alexiel retains many of her high astral powers and Setsuna is almost impervious to injury. Like all of Alexiel039s reincarnations Setsuna was doomed to live a miserable life and die a slow painful death. However the cycle is partially broken when Nanatsusaya kills Alexiel039s previous incarnation. It is then completely destroyed when Setsuna039s younger sister Sara dies in his place. He is hopelessly in love with his sister Sara. He also has no memories of his previous incarnations and at first resents his role as the chosen quotSaviorquot wishing only to protect his and Sara039s happiness. He matures as the series progresses eventually surpassing Alexiel herself. Setsuna is headstrong rebellious and impulsive but he has a good heart and is fiercely loyal to his friends.
