Suggested by Random Kisame is a good swordsman but that won’t be enough to deal with Akame. Her speed is far greater than that of Kisame and she also has good technique with her swings. Kisame just won’t be able to stop her legion of blows and not even his final form will help to save him. Kisame is actually pretty powerful so a few good swings could deal a lot of damage but he is just too slow. Akame wins.
