Something to Fill the Hole

is episode 372 of the Naruto: Shippūden anime.

Summary
Ten-Tails fires its enormous Tailed Beast Ball to the Alliance. Shikamaru, with the help of Ino's jutsu, devises a last-minute plan to counter its powerful attack by creating a barrier and Bee to shoot the Tailed Beast Ball to change its trajectory. However, the ball manages to pierce through barriers of the Alliance and Bee 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 Hokages soon arrive to create a special barrier to block the Ten-Tails. Then Sasuke arrives, much to the shock of the Konoha 11 when Sasuke tells them that he is decided to protect the village and aspires to become Hokage someday. Reuniting Team 7, Naruto, Sasuke and Sakura prepare themselves against 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 losing the feelings of his comrades are much worst than trash and he believes that his comrades will fill the hole inside his heart.
