Alice is an incredible fighter and one of the strongest Integrity Knights out there. With a single swing of her blade she can bring most opponents to their knees. Even Kirito had to comment that her sword felt extremely heavy. While their match would have been close to a standstill for a while, Kirito has obtained abilities even beyond her limit. I don’t really think there’s a whole lot she could do to stop an opponent of his caliber. At this point Kirito has really mastered the sword at a level where no one can reach. Mix that in with his superior physical stats and there isn’t a whole lot that Alice can do here. Kirito wins.
