After leaving Ramen Ichiraku, Kakashi reminded Naruto that creating a technique required a combination of natural transformation and shape transformation. Having completed his training with the Element of Wind, Naruto had the former, and since he already knew how to apply Rasengan, there was also the latter. Naruto thinks that creating a new technique won’t be that difficult since he has already mastered both components, but then Kakashi disappoints him by demonstrating that he can also use Rasengan. Combining natural transformation with Rasengan was too much for Kakashi and even for the creator of Rasengan, the Fourth Hokage. Kakashi is confident that Naruto can handle where they have failed. Meanwhile, Shikamaru points out that Asuma hasn’t smoked a single cigarette after learning of Chiriku’s death, a sign of his concern.
