Kakashi has a flashback back when he was assigned to be the sensei of Team 7. In a bid to know his students, Naruto, Sasuke & Sakura, better, Kakashi spies on them and to see how they would all get along as a group. Angered by Sakura's talk about calling Naruto a brat and that he has no family to tell him right or wrong, Sasuke tells Sakura she is annoying. Realizing Sakura's sadness, Naruto goes to battle Sasuke, but gets defeated. It then goes back to the present and Kakashi claims that it is up to him to stop Sasuke.
