Suggested by Random Kirito is a famous swordsman who figured out that if you die in Sword Art Online, you die in real life. He had an impressive amount of speed and technique. That being said, it simply won’t be enough to claim victory here. Zamasu is simply too powerful and could just end the planet on a whim. It wouldn’t even be that much of a challenge for him. He also surpasses Kirito in speed. Zamasu wins.
