Currently, there is a wave of terrorism in Japan and the police have taken drastic measures to combat it, mirroring those of the criminals themselves. Angel is a member of the Special Security Force and a passionate champion of justice, using her skill in combat to relentlessly bring criminals to justice. While investigating a series of gruesome murders where known criminals are being targeted, Angel and her partner Raiden discover that a trio of psychics, known as the Hunters, are to blame. As the police have little interaction with the psychics, two members of the Hunters begin questioning their involvement. Unfortunately, the third member has received cybernetic enhancements from an unknown source and is an irredeemable psychopath who prefers killing over morality. He sets out on a killing spree, with his first target being the Special Security Force. In order to track down the rogue psychic and expose the mastermind behind the Hunters organization, Angel bands together with her fellow psychics, including the newly-cyborged member. Though daunting and dangerous, Angel knows that justice must be served.
