The government, various corporations, and terrorists are all competing against each other to get their hands on a system that can control the whole world.
In response to the threat of terror and violent crimes all over the globe, the government partnered with global IT firm VOID and launched the Lepton Project to stop criminals.
VOID developed a magnetic field system that corrals criminals into a corner so that law enforcement can apprehend them more easily and thus invented Lepton, a microchip for tracking down criminals.
VX, the secret organization that oversees the global agent market, took the VOID-developed system even further. Partnering with Ray 9 to illicitly modify Lepton technology, they greatly improved it and began distributing it widely within the special agent world.
