Jiraiya's clan's ancestors long ago moved to America, and had been out of contact with Japan for many years.

When Jiraiya was a child, his father was killed by what he thought at the time was a Yokai. Since then, he was raised by Gali, a friend of his father's and his mentor.

He first met the Kakurangers when he was pretending to help the Yokai Oboroguruma. He was, in fact, trying to claim the scrolls Oboroguruma's boss, Azuki Arai, had stolen centuries beforehand. These scrolls would allow him and the other Kakurangers to become Giant Beast Generals. This course of action only resulted in him getting captured and dumped into a volcano. He was saved by his ancestor, who gave him a lecture and entrusted him with a Doron Changer, allowing Jiraiya to become NinjaBlack. He then joined the other four Kakurangers, completing the team.
