Ameyuri Ringo (林檎雨由利, Ringo Ameyuri) is one of the former members of the Seven Ninja Swordsmen of the Mist. Ameyuri was very skilled at utilising the Kiba, twin swords imbued with lightning, which are claimed to be the sharpest sword that were made, having the ability to cut through anything, by apparently functioning in a similar manner to Lightning Release-based chakra flow which she wielded with great dexterit. In the anime, it was shown that Ameyuri uses the Kiba in combination with agile spinning movements, sweeping through her targets while rotating around herself, hitting all enemies around her.
