Misumi Tsurugi was once a ninja from the Hidden Leaf Village but was working secretly for Orochimaru with Kabuto Yakushi.
Misumi is a member of Kabuto’s Genin team working under the command of Orochimaru. Misumi and his team pose as ninja’s from the hidden leaf village, but they are actually from the hidden sound village. The name Tsurugi means sword. Misumi along with his team are assigned to gather information. In the second part of the Chunin exam he fights, Kankuro using his Soft Physique Modification to elongate his limbs, stretching them around Kankuro and breaking his neck. It seems as though he has won, but it is revealed that it was just a puppet, and the real Kankuro was disguising himself as the puppet. Kankuro then uses his puppet to break even bone in the body of Misumi.
