With Earth now left in ruins following the "Nano Hazard," most of humanity has abandoned the planet they once called home along with their physical bodies and rebuilt their digitalized minds into a society within the cyber universe of "DEVA."
A.D. 2400, DEVA's central council detects an incident of unauthorized access into their mainframe. Someone on Earth was trying to hack into the system. The only information DEVA was able to retrieve was that the hacker referred to himself as "Frontier Setter."
To investigate the mysterious hacker's motives, the high officials of DEVA dispatch System Security Third Officer Angela Balzak to the Earth's surface. Equipped with a prosthetic "material body," Angela attempts to make contact with a local agent Dingo, but what awaited her instead was a swarm of Sandworms now infesting the Earth's surface. Angela intercepts the gruesome pests with her exoskeletal powered suit Arhan.
Will Angela and Dingo be able to find Frontier Setter on this devastated planet? Their journey to explore the secrets of the world begins now...!
