Asuma apologises at the grave of the Third Hokage for not understanding his advice concerning who the "king" of the Land of Fire is. At the hospital, Naruto and Sai recover, and Naruto resumes his training. Tsunade receives a report from Kakashi that Akatsuki is once again on the move. Elsewhere, Yugito Nii, the Two-Tailsjinchūriki, is confronted by Hidan and Kakuzu. She quickly unleashes her beast form and attacks them, but is ultimately defeated and captured.
