Kirito is on a roll and he’s not done just yet. Asuna is known as The Flash because of her blinding attack speed and she was one of the most powerful fighters in SAO. That being said, Kirito was at the absolute top of the game and she simply can’t beat him. They fought once and it was actually reasonably close, but Kirito’s battle experience and heightened reaction times will always grant him the win in the end. You need reactions like that to parry Asuna’s rapier. Kirito wins.
