The movie is beautifully animated and an emotional Rollercoaster ride. Topped only by the excellent Soundtrack by Takagi Masakatsu.

A modern approach to the myth of the wolverine in the wolf extincted Japan.

The animation is really fantastic, specially the background staging.

The story is interesting and is quite touching the struggle of the mother to raise her children but at some point it becomes a bit boring for lack of rythm.
