That's what I suspect it will be. Problem is, I feel even though the Sephiroth Graal has made him younger, it wouldn't be enough. Arthur seems to be the ultimate challenge for Kiba, and is part of that whole ideal of Vali vs. Issei and Arthur vs. Kiba at the end of this. Meaning I can't see Vasco beating Arthur to leave Kiba to fight him later, all the suspense would be gone, because defeating Arthur means you still have to beat Vasco to be considered better. No, what probably happens is that Arthur fights Kiba and Lint, and beats them badly, and Vasco fights Arthur and then loses because the SG either couldn't recover all of Vasco's strength, or the process starts to reverse.

Personally, the way Vasco has gotten his youth back to fight superior foes is a lot like how Walter from Hellsing got younger so he could fight Alucard, only to still be too weak.
