Naruto demands that Orochimaru take Sasuke back to the village. Orochimaru advises Naruto to try to use force. Naruto immediately manifests a one-tail chakra cover and attacks him, throwing him back into the woods. Watching this, Yamato recalls a conversation about Naruto’s transformation when he returned to the Hidden Leaf. As soon as Naruto lost his temper he went into transformation mode, becoming more dangerous to himself and others with each new tail. Since the Nine-Tailed Demon Fox would be unleashed if all nine tails manifested, Yamato’s job was to make sure that didn’t happen. When Orochimaru returns, he remarks on the matter that Leaf should be grateful that Yamato was given the ability of the Tree Elemental. He voices his interest in testing Yamato’s abilities, and he was also curious to feel the difference between Sasuke’s powers and “his” Naruto. In response to the fact that Sasuke is Orochimaru’s property, Naruto’s rage grows and he has three tails.
