Time Out says
A female student at a Tokyo uni falls for a mysterious classmate, a shape-shifter descended from wolves. When she’s left to raise their two kids, however, the fact that brother and sister can turn into wolf-cubs drives the family to a mountain farm – though even here they face a troubledfuture. This anime feature takes an intriguing premise and does little with it. The detailed Ghibli-esque visuals are decent enough, but this is disappointingly bland.
