In the Hokuriku region of Japan, the city of Toyama has been covered in an unbroken snowfall for the past ten years. This strange meteorological event has effectively sealed the town off from the outside world, trapping its residents within a quiet, snow-globe-like existence. Rumors circulate that any attempt to leave carries great risk, making the white horizon not just a physical barrier but a psychological one. For high school students Ako and Tako, this frozen prison is the only world they have ever known.

Ako and Tako share a dream. Tako, who possesses a talent for writing, asks Ako to collaborate on a novel. Their goal is to win a literary award, a victory that would grant them passage to Tokyo and a life beyond the snow. For them, the blank page represents a freedom that their hometown physically denies them. Determined to finish their manuscript, the pair manage to travel to Tokyo, leaving the snow behind to focus on their creative work. However, the mysteries of their hometown follow them. As they work to complete the novel, they begin to learn the unsettling truth about the perpetual winter and the test that the isolated town presents to its inhabitants.

The narrative follows Ako and Tako as they navigate the suffocating yet refreshing reality of their coming-of-age story. The setting is specifically modeled after the author Rie Kanous hometown of Takaoka in Toyama Prefecture, incorporating realistic dialects and local scenery. As the story progresses, strange events begin to occur around the pair, suggesting that the abnormal weather is not merely a natural disaster but a phenomenon tied directly to the towns fate and their own futures. The manga explores the tension between youthful ambition and the strange, supernatural weight of home. The first compiled volume of this dramatic and mysterious tale was released in March 2026.
