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, Kurotsuchi suggests that he should retire.

During the trip to the Land of Iron, Kurotsuchi listened to the Tsuchikage's knowledge about the Land of Iron.

When, during the course of the Kage Summit, the Raikage became violent, Kurotsuchi moved to defend the Tsuchikage, taking up a stance behind Akatsuchi. Kurotsuchi and Akatsuchi returned to their initial positions after the Tsuchikage and the other kages ordered their guards to pull back.
