Misumi Tsurugi

is a member of Kabuto's Genin Team.

Chunin Exams arc
Misumi and the rest of his team enter the Chunin Exams to spy on their fellow participants for Orochimaru. During the preliminaries he is matched against Kankuro, who he traps in a stranglehold. He threatens to break Kankuro's neck if he doesn't forfeit, and does so at Kankuro's insistence. Kankuro ends up to be a puppet in disguise, which quickly traps and constricts Misumi. The act breaks every bone in his body and Kankuro is declared the winner.

Land of the Sea arc
Though Misumi and Yoroi are not seen again in the manga, they appear in the anime's Land of the Sea arc. They are research assistants and bodyguards 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. 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 doesn't seem to care, noting that Misumi probably wasn't fully dedicated to fulfilling 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.

Trivia

 * His last name (meaning sword) along with Kabuto (Helmet) and Yoroi (Armor) forms a helmet-armor-sword trio.
