Nobunagun

The year is 1580. Using an army of soldiers equipped with sophisticated weaponry, Nobunaga Oda is on the verge of ruling Japan with an iron fist. One of his enforcers is Ginnai Doma - a fallen samurai reborn into an indestructible killing machine. As Ginnai continues his killing spree on ninjas and those who oppose Nobunaga's rule, Shishimaru of the Iga Ninja - going against the Koga Ninja's plans - pursues a one-man vendetta to avenge the deaths of his comrades and kill the immortal warrior.

A meteor strikes the Earth and is found to emanate a powerful new energy called Beamler, which is used to power a battle robot, GoShogun, and a teleporting fortress, Good Thunder. The Docougar Crime Syndicate, lead by crime lord Neo Neros, try to steal the secret of the energy from the inventor of GoShogun, but he kills himself rather than let them acquire it. His son is targeted by Neo Neros next, but he is taken in by the crew aboard Good Thunder, who travel the world fighting NeoNeros's forces with GoShogun.

In the year 1580, a man named Lord Nobunaga Oda sends hoards of unholy armies across Japan, slaying all who stand in their way. A young ninja escapes her villages' destruction with a short sword, one of the three mystical weapons that can end Oda's rule. During her quest, she is joined by two other ninjas who wield the other two weapons of legend, the sacred sword and spear.

The Western Planet and the Eastern Planet. Once upon a time, the two sides were bound by the "Dragon Pulse" spanning the heavens. The civilization that once had prospered has now turned to a tale of dreams, as the inextinguishable flames of war tear the realm asunder. The two planets remain engulfed in endless battles. The return of the super technology known as "sacred treasures" could revolutionize the world order, but no one knows of them but one person — a "heretical girl." A girl from the Western Panet, Jeanne Kaguya d'Arc, saw heavenly visions of the birth of a "Star Messiah" who will save the world. She embarks on a journey to the Eastern Planet with Leonardo da Vinci, "the one who observes the world." They come across the heretic of the Eastern Planet and "the greatest fool of the day," Oda Nobunaga.
