"Kakashi's Conclusion" (カカシの結論, Kakashi no Ketsuron) is chapter 7 of the original Naruto manga.
Determined to prove himself better than Naruto and Sakura, Sasuke attacks Kakashi. Unlike the other two, Kakashi has difficulty with Sasuke, needing to close the Icha Icha book he was reading so that he can avoid Sasuke's attacks. When Sasuke uses the Fire Release: Great Fireball Technique, Kakashi is forced to stop playing around and immobilises Sasuke. Naruto, meanwhile, frees himself from Kakashi's trap and tries to steal some lunch. He is, however, caught by Kakashi red-handed. Kakashi calls Team 7 together and states that there's no need for the three go back to the Academy, however he advises them to give up on becoming ninja.
