Angel Sanctuary Vol 20

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? -- VIZ Media
