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.
In this final volume, Setsuna and the high angels have entered the Tower of Etenamenki and approached the throne of God. There they find all secrets revealed--the reason for the creation of angels and demons, the origins of the two wars of Heaven and Hell, and the real whereabouts of Adam Kadamon. Meanwhile, the battle outside the Tower rages on. Sara, still possessed by the Angel of Destruction Sandalphon, is intent on destroying the Tower and all inside, as a first step in the destruction of all creation. In the face of this onslaught, can Setsuna prevent the Apocalypse and restore the balance of life on Earth?
