Kushimaru Kuriarare

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

Appearance
r 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
Amidst the battle with the Third Division, the reincarnated previous generation of the Seven Ninja Swordsmen of the Mist are summoned by Pakura and Gari, under Kabuto Yakushi's instruction, with the intention of overwhelming the opposition. Amongst their number is Kushimaru, who after being futilely bombarded by various techniques, retrieves Nuibari from within a scroll in Mangetsu Hōzuki's possession. Entering the fray whilst concealed by a thick mist, Kushimaru begins a silent massacre, impaling a multitude of shinobi before bundling them together. With Zabuza Momochi's defeat, the mist clears, exposing Kushimaru to the enemy. By the time Kakashi Hatake and Might Guy departed for Naruto Uzumaki's location the following day, Kushimaru had been sealed by the Third Division.

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.
