Graduation Exams Arc

Later, during the practical and final test, the class was brought to the training field. There, the entire class was set up to face Shino, Anko Mitarashi and Konohamaru for 24 hours. While the teachers would still evaluate the students' respective improvements, the students' true test was against Kakashi Hatake. The Sixth Hokage quickly explained that he would only pass the first student who is able to take the single bell attached to his hip. With Kakashi as the only obstacles left, Enko and the others faced him. Despite their group assault, Kakashi easily repelled all the students. This however proved to be a setup to get the Sixth Hokage in a group String Light Formation. Despite their effort, Kakashi was still able to hold them off. Ultimately, time ran out with no one getting the bell. However, Kakashi still chose to pass everyone as they succeeded in the test's true goal; teamwork and loyalty.
