Strike Force Zero

Strike Force Zero is an elite, top-secret demon hunting agency of the Japanese government. Unlike the Shih, Strike Force Zero does not believe that shen have any place in the natural order: they are a threat and must be destroyed before they have a chance to destroy humanity.

Overview
Strike Force Zero was founded by Geichin Okamoto, a scion of one of Japan's few remaining ninja families. Encounters with a flock of Tengu and a hsien assassin persuaded Okamoto that the shen posed an existential threat to humankind, and he turned the entire resources of his family into funding Strike Force Zero and a shell company, Dynamic Technology International, to fund it. SF0 operates in several Asian countries, nominally pursuing international criminal activity such as terrorism, drug trafficking, the sex trade, and serial killers. But their real targets are the shen who frequently hide behind these criminal activities.

Membership
The original SF0 agents were recruited from the police and the military, usually those with violent, anti-social tendencies. However, these individuals proved to be poor at coping with the realities of the shen. Later recruit classes drew more heavily on social awkward nerds, people already prone to flights of fantasy, as they had the mental resilience to cope with demons in their midst. They also recruit occasionally from the Yakuza and from professional occultists.

All members of SF0 are declared legally dead and given a new identity. The organization goes so far as to stage an elaborate funeral, and agents undergo radical cosmetic surgery to ensure the truth cannot be uncovered. They also frequently receive cutting-edge medical implants from DTI, such as prosthetic limbs or artificial eyes, to correct physical disabilities that might prevent them from doing field work.
