Kushimaru Kuriarare

is one of the former members of the Seven Ninja Swordsmen of the Mist and a former ANBU.

Appearance
Kushimaru is a shinobi who is noticeably both very thin and tall in stature, giving him an overall gangling appearance. Much like various other members of the Seven Ninja Swordsmen of the Mist, his attire consists of a sleeveless black shirt and matching pants, complete with a waist guard, and Kirigakure's striped wrist and leg-warmers. However, presumably due to his service within the ANBU, his face is concealed by a porcelain mask, with the only exception being the substantial mass of his light colored shaggy hair sticking out. He also wear bandages around his neck much like the other members of this generation of swordsmen.

Abilities
As one of the Seven Ninja Swordsmen of the Mist, Kushimaru was one of the most powerful shinobi ever produced within Kirigakure. In fact, he belonged to the generation that was noted to be the strongest in the village's history. With his long sword, Nuibari, he was not only able to precisely pierce multiple enemies in quick succession, but also stitch them together utilizing 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.

Shinobi World War Arc
Kushimaru, along with the previous generation of the Seven Ninja Swordsmen of the Mist, were summoned by Pakura and Gari under Kabuto's Summoning: Impure World Resurrection technique in order to overwhelm the Third Division forces.

After effortlessly surviving a significant onslaught of various techniques from his aggressors, due to the relative invulnerability granted by the technique that revived him, Kushimaru obtains his former sword from a scroll in Mangetsu Hōzuki's possession. Launching into a onslaught of precise attacks under the concealment of the Hidden Mist Technique, Kushimaru easily bundles together a large group of enemies as the slaughter begins.

Trivia
