"The Chūnin Exams, Concluded…!!" (中忍試験、終了…!!, Chūnin Shiken, Shūryō…!!) is chapter 115 of the original Naruto manga.
Giant snakes begin assaulting Konoha's borders. In the stadium of the Chūnin Exams finals, the ANBU try to come to the Third Hokage's rescue. The Fourth Kazekage takes the Hokage hostage and has the Sound Four seal them in, preventing the ANBU's intervention. The Kazekage removes his disguise, revealing himself as Orochimaru, and promises to kill the Hokage, his old master. Meanwhile, the few Konoha ninja in the audience that were able to avoid the sleeping genjutsu prepare to defend the village. Gaara flees with his siblings, and Sasuke follows them to continue the battle they started.
