Seal of the Holy Vigoor Empire

The Holy Vigoor Empire... a strange dictatorship veiled in secrecy. Its exclusionist foreign policy makes for very few ways to enter the country. One of the only remaining routes is by airship to the capital city of Tairon.
~ Ayane telling Ryu about the Holy Vigoor Empire.

The Vigoor Empire (神聖ヴィゴル帝国 Shinsei Buigoru Teikoku), also known as the Holy Vigoor Empire and the Vigoorian Empire, was the home base of the Greater Fiends Doku and Alma, and the main point of Ryu's quest during the Dark Dragon Blade Incident. The Empire´s capital was the city of Tairon. The Empire, due to its isolationist policies, is only accessible via airship, which service is apparently state-controlled.


An imperialistic nation located in a land-locked area in western Asia. The country remains shrouded in mystery due to its long-standing policy of national seclusion. Vigoor maintains a unique belief system as its state religion. Its leader, the Holy Vigoor Emperor, holds supreme power in both the political and religious worlds; however, details surrounding him are slight. In the Book of The Future on Ninja Gaiden and Ninja Gaiden Sigma, the Empire was established by the Supreme Fiend Gogohn, one of the original Dark Gods.



Gamov is a bespectacled, green hat and coat wearing spy, who constantly shadows Ryu as the latter ventures through the Holy Vigoor Empire. Throughout the game, he sets up Vigoor military forces against Ryu and observes their battles. He claims to know a lot about Rachel and the Dark Dragon Blade. He has a fight with Rachel in Ninja Gaiden Sigma. Though working in cahoots with the Dark Disciple, he is decapitated by the latter with the Dark Dragon Blade at the end.

SAT troops fighting against Ryu

The Vigoor military force comprises MSATs (Mechanized Special Attack Team), MVAPs, the soldiers, and their cybernetic equivalents. The SATs wear the outfits typical of SWAT forces and are the equivalent of rapid deployment forces. They come armed with a variety of knives, pistols, grenade launchers, and rocket launchers. The MSATs deployed on motorbikes or sidecars are called MVAPs. The Vigoor soldiers wear breastplates and helmets with a laser guiding eyepiece. They are equipped with an assault rifle with a bayonet or a rocket launcher.

Military Deployment

The military's elite have undergone cybernetic enhancements.

Vehicle-wise, the military include armored personnel carriers (APCs), main battle tanks and attack helicopters. There are also the FL-2000 series of mini-copters which can independently fly around and attack with lasers, guns, or rockets. Heading these forces are Generals Dynamo and Alternator. The two are large, cybernetically enhanced men wielding plasma guns.


Ninja Gaiden/Sigma[]

Ryu entering Tairon; Capital of the Vigoor Empire.

While training with the Shadow Clan Ninja, Ryu discovers his village under attack by a Samurai army from the Vigoor Empire. Confronting Doku, leader of the forces and Greater Fiend, Ryu is defeated. With his village in ruins, and many of his fellow villagers murdered by the attack, Ryu Hayabusa travels by airship to Tairon per Ayane's suggestion, seeking revenge for his fallen brethren. Upon his arrival he learns many secrets about the Empire, most notably the Fiends; former humans who lose their souls when awakened, the Greater Fiend Doku, who is responsible for the decimation of his clan, and the young and alluring Demon Hunter Rachel. As he fought his way through the capital, Ryu witness many horrors beyond his worse nightmares, and battles all sorts of infernal creatures until going one-on-one with Doku himself. After defeating Doku in an ancient temple area, the MSAT, and the Vigoor Military are transformed into Fiends. At the Labyrinth of Zarkahn, Ryu faces Doku after witnessing Alma's sacrifice for Rachel's life. Although he defeated the demonic samurai, Doku bestowed upon the young Dragon Ninja the Fiend Curse. With the True Dragon Sword slowing the process and preserving Hayabusa's mind, he faces the one who sent Doku to his village, the demonic Vigoor Emperor, who in reality was the reincarnated Vigoor, the ancestor of the Evil Deities himself. After defeating him the curse was removed, freeing him and many others from Vigoor's hold. After destroying the Dark Dragon Blade and his traitorous uncle Murai, Ryu disappears in a swirling wind, as peace was restored to the Empire.
