Bujin Gaim's Army is an army of monsters led by Kamen Rider Bujin Gaim and major antagonists in Kamen Rider x Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle.
The army appeared one day alongside Kamen Rider Bujin Gaim in the World of the Sengoku Period and were used by him to wage war against the other Bujin and warlords. With his army of monsters, Bujin Gaim defeated most of the other Bujin Riders and had them absorbed by the Pitcher Plant Monster.
With the powers of the other Bujin Riders, Bujin Gaim sought to take control of the sacred tree and dominate the entire land under him. However, his army was opposed by Kamen Riders Gaim and Wizard and their allies. Eventually, Bujin Gaim's army was destroyed after the Pitcher Plant Monster was defeated by Kamen Riders Gaim, Wizard, Zangetsu and Beast, and Bujin Gaim was destroyed by Gaim and Wizard, allowing the Riders and their friends to finally return home.
