Kaina of the Great Snow Sea (Ōyukiumi no Kaina) is a breathtaking winter anime that brings a unique blend of fantasy, mystery, and subtle world-building.

This project also marks the 40th anniversary of Polygon Pictures, the studio behind both the Knights of Sidonia anime and this new series. A manga adaptation is also underway—so if you enjoy the anime, you can always baca manga to explore even more of the story.
Setting: A Fragile World Suspended Above a Frozen Sea
In this world, an endless sea of snow covers the planet’s surface, and humanity barely survives atop vast canopies formed by colossal “orbital trees.” On these fragile membranes known as the “Tenmaku,” a single surviving settlement clings to life.
- The protagonist, Kaina, is the only young person left in his elderly community.
- Water is scarce, the giant trees are dying, and holes are opening in the membranes.
- Kaina spends his time learning to read forgotten signs from an elder called “Signboard Ji,” who teaches him that preserving written language has value, even if its meaning is lost.
While the elders believe there’s nothing beyond the Tenmaku, Kaina suspects otherwise—especially after spotting movement through the holes beneath them.
Life Beneath the Membrane: Conflict and Survival
Far below in the snow sea, people still live—but their world is plagued by conflict over water. One such person is Liliha, princess of the small kingdom Atland, who is being chased by enemy soldiers from the military nation Valghia.
Seeking refuge and hoping to find the legendary “sages” who dwell above, Liliha attempts to ascend the orbital tree using a floating insect-like device. As her guards fall in battle, she’s sent alone in a basket to the Tenmaku—her last hope.
The Moment of Encounter: Kaina Meets Liliha
While hunting for food in the form of sky-dwelling insects called “tobikera,” Kaina notices a massive floating creature rise from the hole in the membrane—attached to it is a basket. Inside lies an unconscious girl.
Acting quickly, Kaina cuts the basket free and rescues her, astonished to find a living human—something previously thought impossible beneath the Tenmaku. This quiet yet profound encounter sets the stage for a tale of discovery, connection, and change.
A Stunning Visual Experience
What stands out most in Kaina of the Great Snow Sea is its visual artistry. The translucent canopy, the towering branches, and the endless snowy landscape create a unique and ethereal world. Tsutomu Nihei’s distinct aesthetic from Sidonia carries through here—melancholic yet majestic.
The Tenmaku settlement feels like a forgotten, fading village—haunted by time and age. But there’s also warmth, especially in how the elderly care for Kaina. In contrast, the snow sea below is harsh and war-torn, driven by survival and human conflict.
This clear duality sets up a classic “boy meets girl” structure between two vastly different worlds—an encounter that may redefine both.
