In the year 2035, the world is dominated by advanced science and technology, sophisticated computer systems, and multimedia communication. A unified global government exists, while network wars fought by hackers and the dominance of a single multinational corporation shape everyday life. In this setting, 14‑year‑old Kang Maru, an expert at maneuvering in the RESTOL simulation game, is selected by GEONOID, a company tasked with protecting Earth from natural disasters, to pilot RESTOL 03, one of the five specialized rescue robots. Together with his teammates, Kang confronts a variety of challenges during rescue missions, including a hacker attack that compromises their space‑based rescue station, R‑SAT.
