Aum Shinrikyo, or the Aum Supreme Truth Cult, was a doomsday cult that released sarin nerve gas bombs into the Tokyo subway system some years before Head Shot. The leader of the cult was Shoko Asahara, who was responsible for the attack, by making a deal with Kumicho. Kumicho built the laboratory Satian Six at the base of Mount Fuji, where Hideo Murai (the cult's scientist) produced the gas. From the lab the cult also disposed of their enemies' bodies in industrial sized microwave ovens and dispatched terrorists to murder a lawyer and his family. (Head Shot, Operation Hell Gate)
