Separation

is episode 149 of the Naruto: Shippuden anime.

Synopsis
Naruto arrives at Shiranami's cabin and is captured by the bandits. He escapes by drawing on the Nine-Tailed Fox's chakra, but is recaptured and knocked out. Utakata, who had found a note left by Hotaru and was looking for her, arrives and drives the bandits away with his tailed beast's chakra. Hotaru encounters Shiranami, who reveals himself as the bandits' leader and captures her, taking her to the Tsuchigumo village. He takes control of her and the villagers and takes her with him to unseal the Forbidden jutsu. Naruto and Utakata track Shiranami and Hotaru to the village, but are attacked by the villagers and the bandits, who stall them until Team 7 arrives. Team 7 takes over the fight, allowing Naruto and Utakata to move on to where Shiranami is preparing to unseal the Tsuchigumo Kinjutsu.
