Naruto attempts to reason with Sora, but physical contact causes their chakra to resonate, resulting in Naruto undergoing a partial beast transformation. Recognizing the severity of the situation, Yamato informs Sakura that he is unable to restrain Naruto physically. Consequently, Yamato must engage in a mental struggle against the Nine-Tails' influence to regain control. Meanwhile, Sora successfully recovers his own consciousness and manages to resist the overwhelming demonic power affecting him. This sequence occurs during the Twelve Guardian Ninja arc, specifically identified as the seventeenth episode out of eighteen in the series.
