Ae-oyna-kamuy is taught by Kamuy-huci, the hearth deity, and descends from the heavens to impart his knowledge to humanity. He is responsible for teaching weaving to the Ainu women and carving to the men. He is credited with teaching techniques of fishing, hunting, gathering, architecture, medicine, and religious ritual, and is associated with law and singing.[22] He also fights several battles on behalf of humanity; in one instance, he destroys a personification of famine with his spear of mugwort,[22] then creates herds of deer and schools of fish from the snow on his snowshoes.[22]
