The little girl SHEETA is the descendant of the royal family of the legendary "Laputa, the city of the sky". It was an aerial civilization that surpassed the earthly civilization for thousands of years. But somehow, SHEETA's ancestors left the "sky". "City of the City", abandoning advanced technology and living a secluded life on the ground. However, one day, several unidentified men appeared at her door.
The story begins when the army flying ship on which Cedar is seated is attacked by pirates in the sky. During the battle, Shida fell from a flying boat at an altitude of 10,000 meters. Another protagonist, PASU, was an apprentice of a miner pilot. At the end of the day, he found that something bright in the sky was slowly falling. He ran over like flying, and found that it was a cute girl who floated down from the sky surrounded by blue light.
The next day, Cedar woke up in Baru’s room and found a picture of Laputa, the city in the sky. This is the real city in the sky that Baru's father took the risk of his life and went through hardships, but no one believes him except Baru. So my father died in depression. Baru swears that he must prove to others that there really is a sky city in the world! The pirate with a keen sense of smell soon came to the door. The next is a dazzling chase and escape scene. The last two fell into the deep mine in full view. The flying stone of Ciddy once again shined, making them fall safely. In the mine, the flying rock resonated with the ore underground. It used to be the place where the raw material of flying rock was mined. However, it is said that only Laputa has mastered the technology of refining flying rock. They were caught by the army as soon as they left the mine. Sida was taken to the fortress, where a person named Musca showed Sida a huge robot, which fell from the Sky City, and the technology at the time could not make it restart. That night, Sida recites the help-seeking spell passed down by his ancestors. The flying stone glows, making the robot come alive again, and the entire fortress becomes a sea of fire. Baru took advantage of the chaos and reached an alliance with the pirates and flew into the fortress to rescue Cedar. In a hurry, Shida lost the flying stone, and Musca got the gem, and ordered the army to fly to the sky city according to the guidance of the holy light on the gem. On the other hand, Dora, the pirate mother, calculated the position of the Sky City from the account of Hida, and took Hida and two on the pirate airship to advance at full speed! When it was about to arrive, a tornado suddenly appeared in front of him, and the ship of Musca met in a narrow way. During the battle, the gliders of Baru and Cedar were caught in the tornado. This is the domain abandoned by God, where the terror of nature and the wrath of the gods gather, flying over the thick darkness, in the howling electric light, passing through the corridor of lightning, breaking the boundary between life and death, the gate of destiny once again Open in front of the boy.
The center of the tornado is the legendary flying island "Laputa"! Here is a quiet paradise, only a city in the sky guarded by robots, homes of plants and ancient creatures. Musca caught the pirates and came to Laputa. He forced Sida to enter the central control room with him, activated the text on the black stone tablet, and was about to begin his ambition to dominate the world. Cedar snatched the flying stone. In order to stop Musca, she and Baru chanted the spell that destroys everything: Barus. When Laputa disintegrated, the evil and the weapon system that helped the abuser turned into an atmospheric fireball fell into the sea, and the huge flying stone crystal that floated Laputa in the air carried Laputa’s tree of life and rose to the end of the sky.
