As the pieces fall into place, High Angel Rosiel's master plan becomes clear. With Lucifer under his control, he intends to enter Atziluth, the highest plane of Heaven, through the Gate of the Grand Cross and take control of the Tablet of Heaven, an object that can grant all wishes. Aware of Rosiel's plan, Setsuna and the other angels race to the Gate to stop Rosiel from bringing about the destruction of the world. But the closer they get the more they see that Lucifer may have his own reasons for entering the Gate.
