Kushimaru Kuriarare (, Kuriarare Kushimaru) was one of the former members of the Seven Ninja Swordsmen of the Mist and Kirigakure's ANBU.
Kushimaru possessed the unique longsword Nuibari. With it, he was not only able to precisely pierce multiple enemies in quick succession, but also stitch them together utilising a substantial length of wire attached to the blade. This aptly demonstrated his proficient dexterity while handling this particular needle-like sword, as he was able to repeatedly catch it securely just mere moments after previously forcing the blade through his adversaries.
