To solve international economic crises, all nations have combined into a single entity, the World Coalition Government. The government is totalitarian, telling the populace that what are actually dangerously toxic regions are wilderness preserves, and uses its police forces, the Technological Crimes Task Force (TCTF), to suppress opposition. The player character, code-named Konoko (voiced by Amanda Winn-Lee), full name later given as Mai Hasegawa, begins the game working for the TCTF.
