Naruto Shippuden Episode 64-65

"Jet-Black Signal Fire"

The ANBU troops catch Danzo meeting with a young Rain ninja and bring him in for questioning. Sora tries to look for Asuma, but when he is called in for Danzo's interrogation, follows him there. Tsunade asks if Danzo is plotting something, but Homura and Koharu come in and say Danzo has a good reason for meeting with the ninja. Sora arrives and confronts Asuma, accusing him of killing his father, which Asuma confirms. Sora attacks Asuma, his arm once again assuming a demonic form. While he blows Asuma outside, he is unable to maintain it for long, and falters. He is attacked by an unknown individual, but Naruto shields him from the shurikens, being injured in the process. Sora then approaches Furido, who says that he must kill Asuma and Tsunade to avenge his father and consolidate the "two kings" (the Feudal Lord and the Hokage) into a single leader by eliminating the Hokage. Naruto wakes up that night and catches Sora going after Tsunade. Sora retreats as Shizune and a few other ninja arrive, and Naruto pursues him. At that moment, a mysterious lightning storm strikes, cutting off power to the entire village.

"Lockdown of Darkness"

With Konoha in complete darkness, the village struggles to defend against the four attackers. Meanwhile, Naruto chases Sora for attempting to kill Tsunade. The entire village is in a state of emergency. Asuma, commanded by Tsunade to follow Sora and Naruto, finally catches up to them. Asuma realizes that the four invaders plan to annihilate the entire village using the lightning powers of the corpses that they stole. The revelation shocks Sora. As Asuma leaves to help hold off the attackers, he instructs Naruto to continue to pursue Sora.
