Mercutio is another skilled character from the old Shakespearean days, but he doesn’t have what it takes to defeat Mikasa. She is much faster than him and also more lethal in combat. He would have a difficult time trying to stay one step ahead of her here. My money would be on Mikasa winning in a matter of seconds. I just don’t see this fight managing to stay close since Mikasa could start the fight with a straight dashing slash and I doubt Mercutio could react to it. Mikasa wins.
