Yes Demonicjester01 now Issei have penatre and Ascalon 2, so is possibility to damage Crom Cruach in his PseudoDXD are high. The CXC now is some above Satan Class, in the volume 16 his Ultimate Class and Issei have used only a cannon, maybe a infinity blaster+longinus smasher( with penatre and ascalon 2) can be enough for defeat Crom Cruach. Ascalon 2 is more dragon slayer sword than holy sword.
