Kushimaru Kuriarare

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

Appearance
Kushimaru is both very thin and tall in stature, giving him an overall gangling appearance. He had long, shaggy light-coloured hair. Due to his service within the ANBU, his face is concealed by a white porcelain mask, with a darker-coloured triangle on its lower half, slits for eye holes and Kirigakure's symbol carved on its top. His attire consisted of a sleeveless black shirt, matching pants, complete with a waist-guard, and Kirigakure's striped wrist and leg-guards. He also wore bandages around his neck much like the other members of his generation of the Kiri swordsmen.

Abilities
As one of the Seven Ninja Swordsmen of the Mist, Kushimaru was one of the most powerful shinobi Kirigakure ever produced. His generation of swordsmen was even noted to be the strongest in the village's history. He was capable of using the Silent Killing technique, as seen when fighting the Third Division of the Allied Shinobi Forces while under the cover of his former colleague Zabuza Momochi's Hiding in Mist Technique.

Kenjutsu
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.

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 an onslaught of precise attacks under the concealment of the Hiding in Mist Technique, Kushimaru easily bundles together two large groups of enemies as the slaughter begins. He's then exposed to the enemy, along with Fuguki and Ameyuri, and the other summons, when Zabuza's Hiding in Mist Technique ended due to him being immobilised.

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.
