An anime, amnga and novel series, loosely based on the Mazinger Z concept. Actually not a mecha but a stone giant. The series is considered as part of the Mazinger saga, if not only for the name of the title and that of his creator.
A Japanese teen named Yamato Hino, a young sports enthusiast, during a quiet and ordinary day begins to feel strange calls from an indefinite dimension. Frightened and confused, the boy thinks that he had hallucinations but during a thunderstorm, lightning drags him into a parallel world: the ancient kingdom of Mu, ruled by King Muraji. King Muraji needs someone to defend the capital of his kingdom, attacked by monsters commanded by the evil Dorado of the Empire of Dinosaurs.
In the kingdom of Mu, a legend tells of a titanic being that stands ready to defend the population from any threat. The King wants to awaken the giant statue of the God Mazinger; to do this he needs a brave boy whose name is Yamato, the only one capable of awakening the mighty giant. The devout prayers of the king and the princess are heard: the boy arrives to the dimension of Mu and the statue suddenly becomes alive. A luminous beam covers the boy and he is absorbed into the body of the statue, which begins to move. When the monsters of Dorado broke through the defenses of the kingdom, God Mazinger defeats the dinosaurs and makes the enemy army flee. And thus the legend becomes a reality.
Yamato joins the court of King Muraji, becoming the champion of the Kingdom of Mu, always ready to repel the attacks of the evil Dorado and his fearsome dinosaurs.
