Kuma to Karasu

Somewhere deep in the Japan forest, there is a Moon Bear. In his childhood, he was separated from his family and has never met another Bear. The bear is alone, until he meets the city-raised Crow... The two decide to go on a search for the bear's companion that he's never met before. Passing through the mountains and the forest, the grasslands, volcanos, and lakes, meeting deer and owls, heron, and boars, can the two find their "irreplaceable companion"? What about the existence of "Yatagarasu," the God who "grants only one wish"?
