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 thin and tall in stature. He is the second tallest member of the seven swordsmen next to Fuguki Suikazan. 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, the majority of his face is concealed by a simplistic mask, with the only exception being the substantial mass of his light colored hair protruding outwards.

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 thread attached to the blades hilt. 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' flesh.

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 Mangetsu Hōzuki. Launching into a flurry of furious yet precise attacks under the concealment of a thick mist, Kushimaru easily bundles together a large group of enemies as the slaughter begins.

Trivia

 * roughly means "skewer", and means "chestnut hail"; like all members of the Seven Ninja Swordsmen, his surname is derived from a type of produce.
