In the early 2050s, unknown life forms called “Oracle Cells” began their uncontrolled consumption of all life on Earth. Their ravenous appetite and remarkable adaptability earned them first dread, then awe, and finally the name Aragami, the "Mad Gods." In the face of an enemy completely immune to conventional weapons, urban civilization collapsed, and each day humanity was driven further and further toward extinction.
The year is now 2071... the domain of the mad gods lies here in the Far East.
One single ray of hope remains for humanity. Following the development of "God Arcs" -- living weapons which incorporate Oracle Cells -- their wielders are organized into an elite force.
