Five Kage Summit arc
Kurotsuchi and Akatsuchi escort Ōnoki to the Five Kage meeting. When they are leaving Ōnoki hurts his hips trying to carry his own luggage, so she suggests that he should retire. After arriving in the Land of Iron and the the meeting gets underway, Kurotsuchi comes to the Tsuchikage's defense during the current Raikage's outburst.

When Kurotsuchi hears that Sasuke Uchiha has infiltrated the meeting, she asks for permission to fight the man who killed Deidara. Ōnoki agrees but tells her to keep out of the Raikage's way. She watches Sasuke's battle from the shadows and, when Sasuke causes the room to collapse, creates a dome to protect herself from falling debris. She is also able to fend off Zetsu's Spore Technique.
