"Iruka vs. Kakashi?!" (イルカVSカカシ!?, Iruka Bāsasu Kakashi!?) is chapter 35 of the original Naruto manga.
Irritated that Konohamaru ran into him, Kankurō tries to beat him up. He is stopped by Sasuke. Elsewhere, Konoha's jōnin enter the members of Team 7, Team 8, and Team 10 into the Chūnin Exams against Iruka Umino's objections. Recognising that Sasuke may pose a challenge, Kankurō prepares to fight him but is stopped by Gaara. Sakura asks why three Sunagakure ninja are in Konoha. They explain that the Chūnin Exams are an opportunity to advance in rank before departing, leaving the members of Team 7 intrigued.
