Kin Tsuchi

was a Genin-level ninja from Otogakure. She takes part in the Chunin Exam under orders from Orochimaru to kill Sasuke Uchiha. She is the only one of her team to not have a physical alteration.

Chunin Exam arc
Kin and the rest of Team Dosu attack Sakura during the second phase of the Chunin Exams in their attempt to kill Sasuke. When Team 10 comes to Sakura's aid, Kin's body gets taken over by Ino Yamanaka's Mind Body Switch Technique, and because of that she is injured by her own teammate Zaku.

In the third stage preliminaries she is matched against Shikamaru Nara. Shikamaru initially believes her trick to be a simple combination of needles with and without bells in order to make him less alert of the latter. Kin however follows through using her strings to ring a previously thrown bell, further confusing Shikamaru. Shikamaru counters, contracting his shadow and minimizing it under the string attached to a needle she threw; she didn't notice that a string at that height wouldn't be able to cast a shadow. Shikamaru then proceeded to use Shadow Imitation Technique, to make the both of them throw a shuriken simultaneously. While Shikamaru was able to duck, Kin was too close to the wall and hit her head, knocking her out.

Kin, along with Zaku, is later betrayed and used by Orochimaru as sacrifices to summon Hashirama Senju and Tobirama Senju from their graves with Impure World Resurrection.

Abilities
Kin is an accomplished Senbon user, as seen in the Chunin Exams. When she is ordered by Zaku to "finish Sakura" she reaches into her back pocket and grasps senbon instead of a Kunai or a summoning scroll. In her main technique, Illusion Bell Needles, she also uses senbon. While fighting Shikamaru, she aims at a vital point at his arm and shoulder.
