Jiraiya

Jiraiya was one of the supporting characters in the Narutouniverse. He was an legendary Sannin of Konohagakure, along with Tsunade and Orochimaru, who were trained by the Third Hokage. He was a powerful shinobi and the self-proclaimed super-pervert (although, at least in the manga, he meant it as a joke),and the writer of the popular adult fiction book series, called Icha Icha. He was also known as the Toad Sage (Gama Sennin), because of his signature toad summonings and his status as a sage, who was prophesied to be destined to teach the Child of the Prophecy who would either bring peace to the world, or destroy it entirely
