A young man named Vito has been raised as an orphan in a bitterly cold frontier village. On the day of his coming-of-age ceremony, during a hunt meant to prove his adulthood, he is attacked by a monstrous beast and triggered into remembering his past life: he is a reincarnated Japanese person who was sent to this world to save it. As his memories fully merge, Vito gains the ability to materialize his modern knowledge into physical objects through the help of a local spirit named Shefi, who controls a mystical workshop. With her power, Vito begins to rapidly improve the daily lives of the villagers, crafting tools and introducing innovations that make survival in the harsh climate easier. He also discovers that entering a sauna not only relaxes him but temporarily boosts his physical abilities, making him a formidable fighter against the magical beasts that threaten the settlement. As his contributions grow, Vito earns the trust and respect of the community, including Arrich, the earnest and responsible young woman who leads their clan. Alongside his close friends Yura and Sarp, Vito hunts for food, fends off dangerous creatures, and steadily develops the village, all while enjoying a slow-paced, pastoral life in the snowy wilderness surrounded by fluffy animals. The story follows his efforts to create a personal paradise in the remote north, blending frontier survival, exploration, and the occasional sauna session with the help of the spirits.
