Kurotsuchi

is a ninja of Iwagakure and a bodyguard of the Tsuchikage.

Five Kage Summit arc
Kurotsuchi was setting off with Akatsuchi to escort Tsuchikage to the Five Kage meeting, called for by the Raikage. After the Tsuchikage hurt his hips trying to carry his own luggage, she suggests that he should retire.

When, during the course of the Kage Summit, the Raikage became violent, Kurotsuchi moved to defend the Tsuchikage, taking up a stance behind Akatsuchi. Akatsuchi and Kurotuschi returned to their initial positions after the Tsuchikage and the other kages ordered their guards to pull back. When white Zetsu appeared during the summit, Kurotsuchi and Akatsuchi guarded Onoki. After hearing that Sasuke Uchiha was in the building, she asked Tsuchikage for permission to fight the man who had killed Deidara. Tsuchikage agreed but told her to keep out of Raikage's way.

Having reached the scene of the conflict, she hid behind a pillar, and watched in amazement as Gaara and the Raikage faced off against Sasuke. We later see her looking down at a unconscious Zetsu in front of her and comment on how Zetsu's technique was "creepy".
