Matchless Raijin-Oh

Continues the story of the TV series.

After a slumber of 12 millennia, the Demon Empire returns to seize control of the Earth. Reideen, the giant robot-like protector of the lost continent of Mu, senses the evil presence and awakens within its golden pyramid, revealing to young Japanese boy Akira Hibiki that he is the one descendant of the ancient Mu people who must help Reideen save Earth. He was assisted by his friends, token girl Mari Sakurano (daughter of a scientist fighting the Demon Empire) and several members of his high school soccer team.

In the year 2050 A.D, approximately 1/10th of Japan is now under water due to the global warming effect. The city of Tokyo was no exception. The economy of Japan is crippled from this disaster and the government is willing for anything to help revive the country. As a result, the Japanese government forms "JESAS", a military foundation that has evil intentions of controlling Japan's future. JESAS handles the dumping of nuclear wastes into outer space. To insure their protection from other countries, JESAS has developed "R.B." Robotic Weaponry, which is controlled by pilots with "A.I. (Accurate Intuition)". On the opposite side of the law is the "Green Frontier", a united protection agency that was formed by countries sharing the same beliefs, to save the Earth. Featuring JESAS pilots Kanna and Kazuto and Green Frontier's Doota Kang and Mira Yu, these four youngsters will decide the fate of the Earth through love, friendship and the passion for their duty.

The story is set in “Earthtear,” a mythical world filled with legends and mysteries where monsters, fairies, giants and magicians live. Adeu goes on a journey of training with a robot, Ryu, that has a will and mind to become a real knight. But their enemies have stolen up behind them with the aim of controlling “Earthtear.”
