The ninja bandits have a meeting with their leader about the forbidden technique. Elsewhere, Team 7 tricks Hotaru into letting them stay as her bodyguards until they reach her village. After reminiscing about the past, Utakata wakes up, only to come across the ninja bandits, and fights them until he is cornered by their barrier jutsu, which soon explodes with him inside. Team 7 finally reach Hotaru's village, and they leave her in the village's care, but Naruto senses something troubling and heads back to the village, suspicious of the villagers' attitudes towards Hotaru.
