Nobody talks about this one. A dog becomes a wolf in the Yukon, and the show treats that transformation like a real loss instead of an adventure upgrade. You watch a creature choose wildness over domesticity, and it breaks something in you because the show never pretends that freedom doesn't cost everything. The animation is stiff in places, but that rawness fits a story about a life that refuses to stay civilized. This hits hardest if you've ever felt the pull between the life you're supposed to want and the one your nature is screaming for.
Anime Yasei no Sakebi is a 1982 TV action adventure. AniList describes it as a loose adaptation of Jack London's novel Call of the Wild, while MyAnimeList and AniDB credit it as based on a novel by Hatojuu Muku. The broadcast ran from May to September 1982, and four further episodes followed two years later.
