Well, there's no new HaKox levels for now, and though you can now use the EVS, there is nothing much to do yet. Head for Labyrinthos. At Labyrinthos, save your game and proceed down the main elevator. Enter the first open room which we avoided before and go to the right to open the chest. Inside is the ROSARIO OF GRIEF. Follow the route through the place until you reach the Area 13 Door you couldn't open before. Go through it now, and proceed.
