Misumi Tsurugi

was a shinobi of Konohagakure and a member of Kabuto's Genin Team who later defected and joined Orochimaru and Otogakure.

Personality
Misumi appeared to be overconfident in his abilities and rather sadistic in nature. As shown first in his fight with Kankurō and later in his skirmish against Naruto and Ino he initially appeared confident but let his ego get the better of him. He was also not above using trickery and underhanded methods to achieve his goals.

Appearance
Misumi's appearance was greatly concealed by the mask he wore around his mouth that hung to around his neck and forehead protector which he wore like a bandanna. He also wore what appears to be the standard attire of his team consisting of a high-collared, sleeveless, navy-blue shirt with a short-sleeved, white one underneath, a simple obi around his waist, pants, sandals and fingerless gloves, along with a pair of round framed glasses. After defecting from Konohagakure, he wore a shirt with short sleeves, pants and sandals. It was also revealed that he had spiky black hair.

Abilities
To be more efficient in the gathering of information, he had received a Soft Physique Modification, a surgical procedure that allowed him to dislocate his joints to fit into any space. He then controlled his softened body with chakra, allowing him to stretch and twist any part of his body at any angle, elongating and even coiling around his opponent. In the anime, he was able to create water clones.

Chūnin Exam Arc
Misumi and the rest of his team entered the Chūnin Exams to spy on their fellow participants for Orochimaru. During the preliminaries, he was matched against Kankurō, who he trapped in a stranglehold. He threatened to break Kankurō's neck if he didn't forfeit, and did so at Kankurō's insistence. Kankurō ended up to be a puppet in disguise, which quickly trapped and constricted Misumi. The act broke every bone in his body shy of his neck, and Kankurō was declared the winner.

Land of the Sea Arc
Though Misumi and Yoroi Akadō were not seen again in the manga, they appeared in the anime. They were research assistants and bodyguards to Orochimaru's former scientist, Amachi. He, like Yoroi, had taken off the cloth covering his lower face, and he wore a completely different outfit. During the events of this arc, Ino Yamanaka used her Mind Body Disturbance Technique to force him to tie his arms to pillars in one of the rooms of the labs, and left him there when it collapsed, possibly killing him. When Yoroi informed Amachi about his possible death, he didn't seem to care, noting that Misumi probably wasn't fully dedicated to fulfilling his goals anyway.

Trivia

 * Tsurugi is the name for a samurai's sword. With his former team-mates, Kabuto ("helmet") and Yoroi ("armour"), they form an armour—helmet—sword trio.
