Sometime in the future, terrorism in Japan has become commonplace, and the police have become almost as brutal as criminals. A member of the Special Security Force known as Angel, is the best of the best, stopping at nothing in her fight for justice.

Things get interesting for Angel and her partner, Raiden, when they begin investigating a series of murders in which the victims were known criminals, killed in very unpleasant ways. This trio of killers known as Hunters, is a group of psychics that have banded together to hunt down the lowest scum in the city and bring them to justice.
