Misumi Tsurugi

is a member of Kabuto's Genin Team. Misumi poses as a Genin-level ninja from the Konohagakure during the Chunin exam, along with Kabuto Yakushi and Yoroi Akado. His last name (meaning sword) along with Kabuto (Helmet) and Yoroi (Armor) forms a helmet-armor-sword trio.

Chunin Exams
Misumi attempts to use Soft Physique Modification on Kankuro during the Chunin Exams by catching him in an inescapable hold and breaking his neck. While he seems to have succeeded, he in actuality breaks the neck of Kankuro's puppet, which quickly turns the tables and, as Kankuro claims, breaks every bone in Misumi's body but his neck, removing him from the battle.

Sea Country
Though his fate after the preliminaries in the Manga has never been mentioned, in the Anime, Misumi makes a second appearance with Yoroi in the Land of the Sea filler arc, where he is depicted as a research assistant and bodyguard to Orochimaru's former scientist, Amachi. He, like Yoroi, has taken off the cloth covering his lower face and he wears a completely different wardrobe. It has never been mentioned why he and Yoroi left Otogakure. During the events of this arc, Ino Yamanaka uses her Mind Body Disturbance Technique to force him to tie his arms to pillars in one of the rooms of the labs, and leaves him there when it collapses, possibly killing him. When Yoroi informs Amachi about his possible death, he dosn't seem to care, noting that Misumi probaly wasn't fully dedicated to fufilling his goals, anyway.

Abilities
To be more efficient in the gathering of information he has received a Soft Physique Modification, a surgical procedure that allows him to dislocate his joints to fit into any space. He then controls 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. He has not used any type of elemental jutsu and it's possible that he doesn't know any.
