Sekai Ninja Sen Jiraiya ("Jiraiya: War of the World Ninjas"), also known as Ninja Olympiad, is the seventh Metal Heroes series.Rather than being a Ridiculously Human Robot or a man in a Power Armor, Jiraiya (real name:Tōha Yamaji) is an elite ninja warrior from the Togakure style of Ninpō. His mentor and foster father Tetsuzan Yamaji, the 34th Grandmaster of the Togakure School, has trained him for the day the ancient Yōma Clan will return. Sure enough, the clan, led by Oninin Dokusai, arise with their army of evildoers in order to seize Pako, a mysterious treasure which came from outer space over 2000 years ago which is said to have power equiparable to the Sun. With the help of his family, and an army of international ninja heroes, Jiraiya must stand tall against the evil ones.
Sekai Ninja Sen Jiraiya features examples of the following tropes:
Cool Car: Jiraiya's main vehicle, the Black Saber, is a black Z31-model Nissan 300ZX
Clothes Make the Superman: Played around in an episode where a rival warrior named Yajiro Iyo (played by Kenji Oba) takes the Jiraiya suit away from Toha after defeating him. Toha is forced to fight Iyo without his suit to get it back.
Deceptive Disciple: Kuroi Ibara in Episode 30 betrayed his master's teaching in order to become a criminal.
Distaff Counterpart: Tōha's foster sister, Kei, has her own heroic alter-ego under the guise of Himenin Emiha, who wears white armor, lets her hair hang loose beneath the helmet, and has her legs showing.
Fake Nationality: The actors playing the World Ninjas. Notice how they're always in costume — and how their costumes cover their entire bodies. However, they did manage to get an American to play Rocket Man in a Vietnam flashback though, while Rainin Wild's suit actor was originally a black man before he was switched with a tanned Japanese stuntman.
Legacy Character: Chan Kung-Fu, Makumba, Gyuma and Gamesh are all replaced by identically-dressed successors. Chan's and Makumba's successors in particular are their son and older brother respectively.
Transformation Sequence: Mostly averted. If Toha has to don the armor during the fight, the scene will do a quick cut between him and Jiraiya (one particularly funny case is in episode 30, when Benikiba is fighting Toha; she first pushes him offscreen, and he comes back onscreen less than a second later in the Jiraiya armor). In cases it is shown, it's only a brief sequence.
What Happened to the Mouse?: Benikiba and Retsukiba drop out fighting after Emiha and Manabu have discovered their trick of hiding, leaving his swords and running.
