Jiraiya is a legendary character from the nineteenth-century tale Jiraiya Gōketsu Monogatari (児雷也豪傑物語, “The Tale of the Gallant Jiraiya”). He is often depicted riding or shapeshifting into a giant toad, and is popularly considered to be a folkloric ninja. Jiraiya has been adapted in various pop-culture forms from the nineteenth century to the present day, including novels, kabuki, film, and video games.
Hiroi Michiaki: This one is called Jiraiya, and he’s a legendary ninja. He’s Jiraiya and a ninja and he rides on top of this toad. He does this and that as a ninja does. Truthfully, smoke comes out from here and he dashes off somewhere, that kind of thing. And if you spin this part, the toad, I think it must spin straight and then spin around and around like this.
Mrs. Hiroi: Yeah, it spins around.
