@ Grandpiece dammit because in this tournament until now we don't have see that attack the Volume 25 was Rossweisse's volume and Issei used that attack again Thanathos thanks she, so again Vidar would be perfect. I doubt the Issei will used the Nyuutrom Beam Cannon again Rias's team, but maybe in future using Rias's breast can be powerful enough for defeat Hades.
