"My Fight!!" (オレの戦い!!, Ore no Tatakai!!, Viz: It's My Fight!!) is chapter 147 of the original Naruto manga.
Jiraiya tries to make a grand entrance, but Naruto quickly reminds him that he was gone because he was hitting on a woman. Since the woman was under the influence of a genjutsu, Jiraiya knows that Itachi and Kisame were trying to separate him from Naruto, thereby confirming that Akatsuki really is after the Nine-Tails. Hearing Jiraiya's words, Itachi realises that Jiraiya was the one who informed Kakashi about Akatsuki. Jiraiya prepares to fight them but Sasuke instructs him to leave them to him. Uninterested in their squabble, Itachi tortures Sasuke. Naruto tries to help him and Kisame pursues Naruto, prompting Jiraiya to coat the area in a toad's stomach.
