Naruto's mentor and one of the Three Legendary Sannin. The Three Legendary Sannin were the students of the Third Hokage who survived the Hidden Rain's Hanzo of the Salamander in battle. Jiraiya is also known as the "Toad Sage" for having learned Sage jutsu from the Roads of Mt. Myobu. He was told by the elder that his student will become a savior of the world. Naruto calls him "pervy sage" because he wrote romance novels. He also wrote the epic "Tale of the Gutsy Ninja" with Naruto. During Part I, took Naruto as his student. In Part II, he left to investigate the Akatsuki. He found out it was led by his former student Nagato. Jiraiya died fighting to give the Hidden Leaf a chance against Nagato. He believed Naruto is the child of the Elder Toad's prophecy.
