By 2050, global warming has left roughly a tenth of Japan underwater, Tokyo included, and the crippled government will try anything to revive the nation. It forms JESAS, a military foundation with sinister designs on Japan's future that also sends nuclear waste into space. To guard itself against other nations, JESAS builds R.B. robotic weapons flown by pilots gifted with Accurate Intuition. Opposing it is the Green Frontier, a protection agency formed by like-minded countries to save the planet. Four young people hold the fate of Earth through love, friendship and devotion to duty: Kanna and Kazuto, pilots for JESAS, and Doota Kang and Mira Yu of the Green Frontier. The result is a mecha science fiction action series.
