Don't forget the power of the White one. It was shortly after Ise received his new body that Azazel commented on how everyone was interested in him because he had received power from the four strongest dragons.

Also:  Not sure about Ise becoming super blade warrior-san. Although I can see him boosting Ascalon's holy/dragonslayer aura as a finishing move to completely eliminate the soul of the oppai oppressors.
