Something to Fill the Hole

is episode 372 of the Naruto: Shippūden anime.

Summary
The Ten-Tails fires its enormous Tailed Beast Ball at the Allied Shinobi Forces. Shikamaru, with the help of Ino's technique, devises a last-minute plan to counter its powerful attack by creating a barrier and at the same time have B shoot Tailed Beast Balls to change its trajectory. However, the ball manages to pierce through barriers created by the Alliance and B quickly blocks the ball on his own. The ball suddenly disappeared as Minato arrives, telling the Alliance that he teleported the ball to the sea. The other revived Hokage soon arrive, and were quickly confronted by Madara, but he was told to wait by Hashirama since he and the other Hokage had to stop the Ten-Tails first. The Hokage proceeds to create a special barrier to block the Ten-Tails, and Hashirama makes several Torii to pin it down. Then Sasuke and Jūgo arrives, much to the shock of the Konoha 11 when Sasuke proceeds to tell them that he has decided to protect the village and aspires to become Hokage someday. Reuniting Team 7, Naruto, Sasuke and Sakura prepare themselves against the Ten-Tails. Meanwhile in the Kamui dimension, Obito continues to berate Kakashi about the failing reality in this world and value of comrades but Kakashi tells Obito that people who lose the feelings of his comrades are much worse than trash and he believes that his comrades will fill the hole inside his heart.
