The angel Alexiel loved God, but she rebelled against Heaven when she
saw how disgracefully the other angels were behaving. She was finally
captured, and as punishment sent to Earth to live an endless series of
tragic lives. She now inhabits the body of Setsuna Mudo, a troubled
teen in love with his sister Sara. Setsuna's misery mirrors the chaos
among the angels, and their combined passions threaten to destroy both
Heaven and Earth.
