Hayao Miyazaki’s Castle in the Sky(Studio Ghibli Official) was released on August 2, 1986. It was Studio Ghibli’s first film—or, rather, the studio was founded to make it. It remains a favorite, and I imagine many people would name it as the Ghibli film they love most.
I love it, too. As a child, I went through a period of watching it almost every day. Here, I will recount the story and consider three of its mysteries. But a warning: this synopsis tells the whole story, including spoilers through to the ending. If you want to avoid them, stop partway through and watch the film first.

Pazu’s Quest: One Way to Read the Story
You could describe Castle in the Sky as an adventure to find a legendary island hidden in the clouds. For Pazu, I think it is also a journey toward recovering his father’s good name.
Pazu’s father photographed the floating island, but was treated as a fraud and died in despair. Perhaps Pazu builds his ornithopter amid his exhausting work because he wants to vindicate him.
Yet I suspect that even Pazu must have felt some doubt about Laputa. Seen this way, Sheeta’s descent from the sky must have seemed a miracle to him: a reason to hope that what he wanted to believe might be true.
From this perspective, Pazu’s determination to protect Sheeta can be read as his response to the hope she has brought into his life.
With that possible reading in mind, let’s follow the story in detail.
Detailed Synopsis: A Scene-by-Scene Story Breakdown
Part 1: The Girl Who Fell from the Sky
The story follows Pazu, a boy who works as a laborer in a declining mining town. Even though he is still a child, his days are hard. That evening, he is working late, surrounded by the town’s kindhearted people.

Returning to work with food for the night, Pazu sees a mysterious light drifting slowly down from the sky. Looking closer, he realizes it seems to be a person.
Pazu hurries toward the falling figure. When he reaches her, he finds a girl with braided pigtails, a strange stone glowing at her chest.

The following morning, the girl awakens in Pazu’s humble home. Disoriented, she follows the crisp sound of a trumpet up to the roof, where she finds Pazu greeting the sunrise. They formally introduce themselves: the boy is Pazu, and the girl from the sky is Sheeta.

After they introduce themselves, Pazu asks to borrow the stone hanging from Sheeta’s neck. He thinks it caused the strange sight he witnessed the night before. Putting it around his own neck, he jumps off the roof.
Unfortunately, the stone does not do what Pazu hoped. Luckily, he escapes with only minor bruises.

They recover and decide to eat. While Pazu prepares the meal, Sheeta notices a photograph of a strange castle rising above the clouds. Pazu explains that it is Laputa, an island in the sky, photographed by his father.
He explains the tragic backstory: his father was ridiculed as a charlatan until the day he died. Driven by a fierce determination to prove his father right, Pazu reveals the skeletal frame of an ornithopter he has been building by hand.

An automobile stops outside Pazu’s house. He is excited to see such an unusual vehicle, but Sheeta reacts differently. She says its passengers are pirates who are after her. Pazu acts to protect her.
With help from the townspeople, Pazu and Sheeta shake off the first pursuers. But Dola, the pirates’ leader, keeps after them, and the children are soon in trouble.

The children flee along the railway tracks. Under pressure from Dola’s pursuit, they fall into the depths of the mine. Then another miracle occurs: the stone at Sheeta’s neck glows, and their bodies float in the air.

Drifting slowly into the mine’s caverns, they escape Dola and her crew. In the disused mine, they finally have a chance to eat.

An old man appears. Sheeta is wary, but Pazu knows him: Uncle Pom.
Uncle Pom says the rocks are “stirring,” and that he likes being in the cave when this happens. He breaks open a small stone. Its interior glows blue for a moment, then returns to normal. He puts out the light and looks around.
The rocks in the cave begin to shine like stars. Uncle Pom explains that the area’s rocks contain Levistone, which glows in the dark.
Sheeta notices something strange: the stone around her neck is glowing brightly.

Her stone is crystallized Levistone. Uncle Pom says that only the people of Laputa knew how to crystallize it. He has also heard that the rocks stir because Laputa is passing overhead.
Pazu is delighted. Having sought Laputa alone since his father’s death, he has finally heard someone affirm its existence. And after floating through the air through the stone’s power, Laputa is now real to him.
After Uncle Pom shows them out of the cave, Pazu’s thoughts turn increasingly to Laputa. Sheeta tells him the secret name she inherited: “Lusheeta Toel Ul Laputa.” He is astonished to hear Laputa in her name. But soldiers surround them. The pirates were not the only ones looking for her.

Pazu tries desperately to protect Sheeta, but the soldiers vastly outnumber them. Both children are captured.
Part 2: The Fortress and the Awakened Guardian
Pazu is put in a cell. Sheeta, though confined to a tower, is treated well. A man called Muska takes her deep beneath the military facility, where a strange, broken robot lies motionless.

Muska is directing the military’s search for Laputa, but it was this robot’s fall from the sky that prompted them to take the search seriously.
Muska knows Sheeta’s secret name, too. He presses her to reveal the words that activate the Levistone.
Sheeta says she knows no such words and begs to see Pazu. Muska tells her that if she cooperates, he can set Pazu free. She gives in.
Pazu is unexpectedly released. Sheeta seems like a different person as she tells him to give up on Laputa. Pazu is confused, while Muska practically forces money on him as thanks for “protecting her from the pirates.”
Faced with overwhelming force, Pazu can only yield. Blaming himself for his powerlessness, he quietly heads home. He considers throwing away the money he accepted, but cannot bring himself to do it. Days of hard work in the mine should have been waiting for him…
When he arrives home, however, he finds the pirates who had pursued Sheeta occupying it and eating.

Tied up in his own living room, Pazu is mocked by the pirates when they discover the bag of gold. “Did you sell the little girl out?” they laugh.
“Sheeta told me to!” Pazu protests, but Dola dismisses it. “Don’t you understand the heart of a woman who tried so hard to save you?” Only then does he understand what Sheeta meant.
Just then, the pirates intercept a military transmission and set off again to seize the Levistone.
Pazu begs to go with them. Calculating that Sheeta may be more cooperative with him there, Dola allows him to join.

Unaware of this, Sheeta sits alone in the tower. She remembers her grandmother teaching her a spell to restore her spirits in difficult times. As she quietly says the words, the Levistone at her neck begins to shine brightly.

As if responding to the light, the dormant robot below comes back to life and begins to move, searching for something.

The robot’s tremendous firepower devastates the base where Sheeta is held. Finding her, it continues its destruction as if trying to protect her.
Simultaneously, Pazu and Dola arrive amidst the fiery chaos. Navigating a nimble pirate “flapter” (a small ornithopter) through thick smoke and explosive anti-aircraft fire, Pazu performs a breathtaking mid-air maneuver to pull Sheeta off the burning tower.

In the confusion, Sheeta loses the Levistone, but manages to return to Pazu.
Without the Levistone, the children are no longer being pursued by either the military or the pirates. Still, they ask to accompany the pirates in search of Laputa. Dola is reluctant, but her crew welcomes the prospect of handing over their chores. This apparently good-natured group is known as the Dola Gang, after its leader.
Part 3: Through the Dragon’s Nest to Laputa
The search party led by Muska now has Sheeta’s Levistone and follows the light it projects. The words she remembered have made it point toward Laputa.
Sheeta no longer has the stone, but remembers where its light first pointed. Acting on her account, Dola steers the Tiger Moth toward Laputa. Meanwhile, the children do chores aboard the ship.

As they approach Laputa, they keep watch for the military flagship, the Goliath. Pazu takes his turn on lookout duty. Sheeta joins him; he worries about her and tells her to go back, but they end up keeping watch together. They share a special time there.

The tranquility shatters when Pazu spots the massive silhouette of the Goliath emerging from the clouds directly beneath them. The Tiger Moth takes violent evasive action, deploying the crow’s nest as a tethered reconnaissance kite with Pazu and Sheeta inside.
They spot the Goliath again, and its fierce attack puts the Tiger Moth in danger. Then the group encounters the enormous storm called the Dragon’s Nest. Dola wants to turn away, but Pazu urges her to go in. He remembers his father’s words: he found Laputa within that storm, behind winds blowing the opposite way like a barrier. Dola resolves to enter, but just then the Goliath scores a direct hit on the Tiger Moth.
The attack severs the kite from the Tiger Moth, leaving Pazu and Sheeta to be swallowed by the Dragon’s Nest alone. Amid the wind and lightning, Pazu feels as though he has seen his father…
When they finally regain consciousness, the deafening roar of the storm is gone, replaced by the tranquil sound of chirping birds. They step out of the wrecked kite and find themselves standing on soft grass, surrounded by ancient, overgrown architecture. They have finally reached Laputa.

Unfortunately, they are not the only ones to reach Laputa. The soldiers from the Goliath are there, plundering it. One consolation is that Dola’s crew, though captured, is still alive.
Pazu decides to rescue the Dola Gang, who have helped him.
The children get close to the captive Dola, but Muska catches Sheeta again. Using the Levistone, he disappears with her beyond Laputa’s walls. Pazu has little choice but to rescue Dola first.
Using the chaos of the greedy, looting soldiers as cover, Pazu manages to liberate the pirate crew. As a parting gift, Dola tosses Pazu a massive hand cannon, urging him to save the girl.
With the Levistone’s power, Muska reaches Laputa’s central core. There he reveals that he, too, has a secret name bearing Laputa’s name: Romuska Palo Ul Laputa. Both he and Sheeta descend from its royal family. While her family placed its future in life on the ground, his never lost its longing for Laputa.

With the Levistone in hand, Muska overrides the city’s systems, declaring himself the absolute King of Laputa.
The soldiers who accompanied Muska are bewildered by his claim, and their existing hostility toward him comes into the open. But with Laputa under his control, Muska attacks them. Robots of the same type as the one that fell to earth come to life at his command. The soldiers can only flee, and the robots continue to pursue them.
Amid the confusion, Pazu approaches the core where Muska and Sheeta are. Sheeta takes her chance to escape from Muska and searches for Pazu.
Muska finds Sheeta first, but Pazu reaches her soon afterward. Once again, he confronts Muska.

Muska remains confident in his shooting even with Pazu’s cannon aimed at him. He gives the children a little time together. Pazu suggests using the words Sheeta mentioned on the Tiger Moth—the words that will end everything. This is his final decision.
As Muska raises his gun to execute them, Pazu and Sheeta hold the Levistone together and scream the Spell of Destruction: “Balse!”

At that instant, Laputa, which had barely held together, begins to collapse.
The Dola Gang tries to escape in its Flaptters, waiting for Pazu and Sheeta until the last possible moment. But the children, knocked unconscious by the spell’s impact, do not return. With no choice but to leave, the pirates fear they have died.
Miraculously, the tree’s branches have caught the unconscious children and saved them from the collapse. Narrowly surviving, they leave Laputa in the kite that brought them there.

The children locate their intact glider, take flight, and joyously reunite with the surviving pirates in the sky above. After a tearful, heartwarming farewell, Pazu and Sheeta fly off into the horizon.
Pazu’s adventure, which began with a single photograph left by his father, is over. At last, his life can begin. What sort of life will he lead with Sheeta?
That is the story of Castle in the Sky. Trying to summarize it made me realize how tightly the screenplay is put together: there was almost nothing I could leave out. Perhaps that precision is what gives it such a lively pace. Some sequences are also captivating on screen but extremely hard to put into words. I think a visual work is best enjoyed as a visual work.
Now, let’s peel back the layers and dive into the deeper analytical mysteries hidden within the film.

Castle in the Sky (1986): Analysis and Unanswered Questions
The film’s adventure leaves questions about its characters, machinery, and floating island. The discussions below consider how those details shape the story.
The Enigma of the Fallen Robot Soldier
Muska is a striking presence in the film, but the basic reason he can mobilize the military to search for Laputa is the robot’s crash.
The event fits so naturally into the story that we readily accept it. But why did that robot fall from Laputa?
The linked article sets out my own somewhat far-fetched explanation, and also considers what the robot’s fall means in the story. If you have time, please take a look.

Before meeting Sheeta, Pazu works hard on his ornithopter. His aim, of course, is to reach Laputa.
But why does he feel he must reach it? Surely he wants to vindicate his father, who died being treated as a fraud. Yet I think his feelings cannot be explained quite so simply.
Why does he work so hard on the ornithopter night after night? The linked article follows that question in more detail, through his words about the wind.

Uncle Pom makes a lasting impression despite his brief appearance. His role is to help Pazu believe in Laputa. With Sheeta’s arrival and Uncle Pom’s testimony, Pazu can finally believe it is real.
He seems to leave an impression beyond what that role alone would explain. Thinking about why leads me to another possibility, which I explore in the appendix to the linked article.
That appendix also discusses Uncle Pom as a descendant of Laputa’s working class, drawing on Hirokatsu Kihara’s production memoir, Another “Balse.”
Read the full analysis: The Missing Character and Uncle Pom’s Secret RoleAppendix: How Did Pazu Carry Sheeta Home?
Perhaps the film’s greatest mystery is how Pazu carried the unconscious Sheeta all the way to his house. I have not reached a conclusion.
At first, Sheeta is laid beside a huge gear. Pazu has to get her down from there before he can take her home. It would be difficult even for a strong grown man.
Yet Pazu does get her down and carry her home. I still have no answer. You could say, “They probably didn’t think that far ahead,” but I believe Miyazaki would have. At the very least, I cannot imagine producer Isao Takahata overlooking it.
How did Pazu carry Sheeta? What do you think?
