Event Year: 2007

Naruto's been having nightmares about the release of the Nine-Tail's power. Afterward, Kakashi informs Naruto that he has special training for him that will make him strong quickly. They are cut off by Team 10, who have also come to visit. Sai lunches with them and, trying to make friends by using nicknames, angers Sakura by calling Ino "gorgeous" after concluding that women do not like to hear how they really are.

Orochimaru and Kabuto convince Sasuke to withdraw with them, and Naruto weeps over his failure to return Sasuke to the village, but Sakura reassures him that they will bring Sasuke back together. Naruto's team reports to Tsunade about the results of the mission, and Tsunade is greatly angered over Danzo's scheme, particularly his leaking classified information to further it. Sai asks Danzo to allow him to remain with Team Kakashi, and Danzo reluctantly agrees. Sai goes on a mission with his team, having come to see them as his friends.

Sasuke begins to attack Naruto, but Sai restrains him only for them both to be blown away by Sasuke's Chidori Nagashi. Sakura charges at Sasuke, but Yamato intervenes and winds up being stabbed by Sasuke's unique blade infused with his Chidori. The Nine-Tailed Fox tempts Naruto with its power, but he refuses it. Sasuke sees this using his Sharingan, appearing in Naruto's mind. The Nine-Tails says that Sasuke's chakra reminds him of Madara Uchiha, then Sasuke suppresses the Nine-Tailed Fox's chakra. Before the Nine-Tailed Fox returns to its cage, it warns Sasuke not to kill Naruto, saying that he will live to regret it forever.

As Team Kakashi continues their search for Sasuke, Sai approaches Sasuke's room and awakens him. Shaken by the image of Sasuke's Sharingan from earlier, Sai attempts to restrain him. A large explosion occurs and Sakura, Naruto and Yamato catch up. At first Sakura tries to restrain Sai in order to find out his true objective, but she stops, stunned at seeing her former comrade. Contrary to what the rest of the team assumed to be his mission, Sai tells them that he wishes to bring Sasuke back to Konoha.
