In 2035, advanced science and technology, sophisticated computer systems, audio/video multimedia converstions, worldwide government unification, network wars by hackers, and a future world dominated by a single massive multinational corporation define the era.

Together with his teammates, he faces numerous challenges in their duty, including a hacking attack on their space-based rescue station, R-SAT.
