Sugimoto visits an Ainu village where he learns about their ways and culture. The next day he leaves in secret, where he is captured by the 7th and tortured.

Two hunters are after Retar, the last of the Ezo wolves, and the last living wolf in Japan. Both of these hunters have tattoos, and Sugimoto wants them for himself. It's a battle between hunters and prey in the snowy mountains of Hokkaido.
