Ashimi

Ashimi is a green lichen with a double significance: in the northern forest it is a valuable winter food for pyuika, while its vivid scent becomes part of Van’s bodily experience and, later, its extract offers a promising lead in research on mittsual. The lichen joins everyday animal care to the novel’s larger question of how disease, diet, and the relations between people and their environment are connected.

Appearance and Perception

When Van enters the forest, the scents of mosses and lichens suddenly strike him with extraordinary force. Their separate odors surge together like a thousand tiny bells, and Ashimi is the strongest: a beautiful green growth clinging abundantly to the roots of a great tree, with a complex fragrance that resists description. The scene makes a familiar part of the forest newly perceptible to Van; he had not previously realized that Ashimi possessed a scent at all.

The scent does not simply delight him. As he takes it in, a quiver passes through his body, and the countless tiny creatures within him seem to divide, repel one another, swirl together, and subside. The pack slows, and Yuna slows with it as the beasts shake their heads, apparently perplexed. When Van halts, Ashimi’s scent seeps into him like surf lapping a shore, and the impulses within him gradually quiet. Yet the stillness is not uncomplicated: at the thought that all will soon be quiet, pain shoots between his eyes, and the reins of light pull at him again.

Winter Fodder and Herding

Ashimi also has a concrete place in the work of raising pyuika. During mating season the animals eat large quantities of the lichen, and after giving birth they seem to crave it. In winter it grows fresh in the woods even under frost, so gathering it and feeding it to the animals is an important task. The work is arduous: herders slog through deep snow and dig up the lichen, but they depend on it if they want their does to bear strong calves.

Van’s new ability to find Ashimi by smell makes that labor a little easier. He places a bundle on the snow in front of Tsupi before joining Yoki, tying the remarkable change in his perception to an ordinary act of care. But the same scent also agitates him. Unlike mohoki, Ashimi has a pleasant odor that both attracts and repels him, stirring inner turmoil and bringing back memories of the night the rochai came. The lichen’s usefulness and its emotional charge therefore remain inseparable: it is both fodder sought out for the herd and a sensory trigger bound to danger.

Medical Research and Disease Resistance

Ashimi’s importance extends from herding into the investigation of mittsual. Asked about the anti-mittsual drug, Hohsalle says it has been partially effective; its precise effect is not yet understood, but it appears to have potential. The drug is made from an Ashimi extract, an achievement credited to Milalle, who has studied lichens for many years.

The discovery prompts a broader hypothesis rather than a settled explanation. Tomasolle observes that Ashimi is widespread and that lichens and mosses are symbiotic, with numerous similar species. Ashimi and related lichens appear to share disease-resistant properties. He suggests that people who regularly eat reindeer, or other animals that feed on such lichens, may themselves be resistant to the disease. Hohsalle agrees that Milalle suspects the same connection and reports her proposed way to investigate it: compare foods favored by Aquafaese people with those avoided by Zolians.

Significance

Ashimi links several kinds of knowledge without making them interchangeable. For pyuika herders, its value is practical and seasonal: it can be dug from beneath the frost and fed to animals expected to bear strong calves. For Van, it is a scent newly revealed to the senses, capable of calming an inner disturbance but also of drawing him back toward a traumatic memory. For the researchers, it is the source of an experimental drug and a possible clue to why some populations resist mittsual.

The progression from a lichen on a tree root to an extract under study widens the story’s attention from an individual body to the food chains and habits that may shape collective vulnerability. The proposed connection between lichen-fed animals, human diets, and resistance remains a hypothesis, and the drug’s effect is only partly understood. Ashimi matters precisely at this point of uncertainty: it offers a tangible lead, not a completed cure or a final explanation.
