By the year 2050 AD, roughly one-tenth of Japan has become submerged as a consequence of global warming, and Tokyo is no exception. This catastrophe has severely damaged Japan's economy, leaving the government desperate to revitalize the nation. To that end, the Japanese government establishes "JESAS," a military organization with sinister ambitions to seize control of Japan's future. Among its activities, JESAS oversees the disposal of nuclear waste into outer space. For its own security against foreign threats, JESAS creates "R.B." Robotic Weaponry, piloted by operators who possess "A.I. (Accurate Intuition)." Standing in opposition is the "Green Frontier," a unified protective coalition formed by like-minded nations dedicated to preserving the Earth. The story centers on JESAS pilots Kanna and Kazuto, alongside Green Frontier's Doota Kang and Mira Yu, as these four young individuals determine Earth's destiny through love, friendship, and unwavering commitment to their roles.
