When Jiraiya saw young Nagato’s Rinnegan, he decided to train him, Konan and Yahiko so that they could protect themselves and others. Believing that the Rinnegan originally belonged to the founder of the ninja world, Jiraiya also wished to train Nagato to control his powers for the benefit of the world. One day he taught them everything they needed and left them alone, after which he heard that they were dead. Although Jiraiya was glad that it wasn’t true, he told Konan that Akatsuki’s activities were a mistake and couldn’t be ignored. Then Pein shows up and proves the assertion untenable. Seeing Paine’s Rinnegan, Jiraiya assumes that he is Nagato, even though he looks completely different.
