Naruto: Shippūden (2007)

S3E64 Jet-Black Signal Fire

Danzou is taken in for interrogation after being spotted with a young ninja from the Rain village. Sora confronts Asuma, who shockingly confesses to killing Kazuma. Enraged, Sora attacks Asuma, his arm transforming into a demonic shape once more. Soon after, Naruto gets hurt while trying to protect Sora from an unidentified attacker, likely affiliated with Root. Furido then encourages Sora to take revenge on both Asuma and the Hokage for his father's death. Later, Naruto catches Sora heading towards Tsunade but Sora retreats as Shizune and other ninjas arrive. Naruto follows him just as a mysterious lightning storm hits, plunging the village into darkness.
