Bureau of Espionage

During the Edo Period(1603-1867) the eighth shogun, Tokugawa Yoshimune, established the Oniwabanshu - a group of government-employed undercover ninja agents: onmitsu.

Though it's not public knowledge, they're an official organization that still exists today as the Bureau of Espionage. Their main job is intelligence gathering and manipulation, both domestically and internationally, as well as the surveillance and elimination of Mononoke.

Since the Edo Period, Mononoke have seldom caused disturbances, and in modern times the Onmitsu's missions have been predominantly human related. They serve as bodyguards for VIPs, investigate dangerous organizations, etc. Due to this the number of their agents who can deal with Mononoke related threats is at a critical low.

The Onmitsu has several covert bases disguised as ordinary office buildings, warehouses, and apartments, and runs several shrines across Japan with secret Onmitsu facilities. One such shrine secretly contained the n/a (killing stone) Rago was sealed inside of.

Tokimasa Azuma described being an Onmitsu as living in a "shadowy world... where the light of the sun doesn't reach...". Both he and Ichika Kishimojin's parents wanted to spare their children from becoming Onmitsu but were unable to do so.

According to Shiba, the Oniwabanshu were the ones who brought about the switch from the Shogunate to the new government during the Meiji Restoration.

According to Amagi the Onmitsu were created specifically for the purpose of eliminating Mononoke.
