Reideen the Brave

After sleeping for twelve thousand years, the Demon Empire rises again to conquer Earth. Reideen, a giant robotic guardian of the lost continent of Mu, senses their malevolent return and awakens inside its golden pyramid. It reveals to Akira Hibiki, a young Japanese boy, that he is the last descendant of the ancient Mu people-and the only one who can help Reideen defend the planet. With the support of his friends-including Mari Sakurano, the daughter of a scientist battling the Demon Empire, and some of his high school soccer teammates-Akira must rise to the challenge.
