Jiraiya Goketsu Monogatari

Jiraiya (自来也 or 児雷也^?, literally "Young Thunder"), originally known as Ogata Shuma Hiroyuki, is the toad riding character of the Japanese folklore Jiraiya Gōketsu Monogatari (児雷也豪傑物語^?, "The Tale of the Gallant Jiraiya"). The tale was adapted into a 19th-century serial novel, a kabuki drama, several films, video games and a manga, and has also served as a source of influence for various other works.

In the legend, Jiraiya is a ninja who uses shapeshifting magic to morph into a gigantic toad. As the heir of a powerful clan in Kyūshū of the same name, Jiraiya fell in love with Tsunade (綱手), a beautiful young maiden who has mastered slug magic. His arch-enemy was his one-time follower Yashagorō (夜叉五郎), later known as Orochimaru (大蛇丸), a master of serpent magic (the kanji 大蛇 literally means "giant snake" or "serpent"). It was first recorded in 1806.
