Feast Ninja Gyuma

Feast Ninja Gyuma (祭忍 ギュウマ): A ninja from Cambodia who seeks to defeat Jiraiya in order to become the world's best ninja and obtain the Pako board. He can shoot an electric shock from his horns, and can create underlings from his own cloth. The original Gyuma is defeated by Jiraiya in Episode 13, but his identity is later assumed by a successor. In Episode 42, Gyuma's successor sends a female ninja named Akiko Masumoto (松本 秋子), a dead-ringer for Tetsuzan's late wife, to spy on the Yamaji family. However, Akiko betrays the second Gyuma after befriending the Yamaji family, particularly Manabu.
