Mifune has proposed that Danzo should lead the five-village alliance to deal with Akatsuki, to the shock of the other kages, because only Konohagakure has the only remaining Jinchuriki. However, Ao suggested that Danzo is using his Sharingan to control Mifune. After Zetsu interrupted the Kage meeting he ordered two of his men, Okisuke and Urakaku, to locate Sasuke Uchiha at all costs. Later he reprimanded Danzo for using the Unnamed Mind-controlling Dōjutsu, as Ninjutsu was forbidden in the meeting.

Later, when Sasuke infiltrates the summit, he watches as White Zetsu is attacked by the Raikage. He is present when Sasuke finally reaches the meeting room, and is the first to attack him. He manages to suprise Sasuke with his attack, but it is never-the-less deflected. Mifune compliments Sasuke on his sword skills.
