Once upon a time, there were five great nations, Shugoddam, N'Kosopa, Ishabana, Gokkan, and Toufu. Each country had its own ruler, who was allowed to fight by arming oneself in the form of a warrior with one's sword. According to tradition, it was said that the Earth Empire Bugnarok, an enemy supposed to have been defeated once 2,000 years ago, would rise again this year, and they were to fight against it. The rulers of the five countries had gathered in Shugoddam, the most powerful country in the world, to form an alliance in preparation for the return of Bugnarok...
The country "Shugoddam" where the guardian deity resides is in a pinch by the "Bugnarak" army revived from the emperor, but it is saved by Gira, who transforms into Kuwagata Ohger. However, he is chased by Shugoddam's soldiers for defying King Rcules. The one who helped Gira was the king of N'Kosopa, Yanma.
With the help of the people of N'Kosopa, Yanma and Gira defeat the enormous Bodarujim. The one who suddenly kidnapped them was Hymeno Ran, the queen of "Ishabana". Hymeno, who has a super selfish personality and wields Gira and Yanma, actually has a secret...?
Gira and Yanma learn of Hymeno's unusual selfishness and hidden considerations for the nation. In front of the three rulers, one of the three major guardian deities "God Kabuto" appears. The one who was riding God Kabuto was the lord of "Toufu", Kaguragi Dybowski. What is the nature of Kaguragi, who is thinking about something bad...?
