Matagi (traditional winter hunters of the Touhoku region of northern Japan) hunted animals deep in the Ou Mountains. They used ancestral methods to hunt down bears. One of the Matagi men is Sanshiro.

The Touhoku region, where the strong will of human beings and the harshness of nature compete. Gunshots now endlessly echo in the mountains of Ou. They are a group of hunters called "Matagi" who use guns and kill their prey with deep knowledge and skill. Nature is an enemy and a unique friend to these people who live with the depressing seasons. The stories told through their eyes are full of the abundant scent of Yamano. There is a lineup of all kinds of characters, such as the young Matagi man Sanshiro, who is known as "Wild Strawberry Drop", and Sarumaru, a master of rapid fire with contraindications.
