The story is set in Japan’s Warring States period. It follows Tono, a man who was once a fearful god on the battlefield but has fallen into poverty and is now living in a tenement house, and a dog that he picks up despite his inadequate daily life. Tono is pushed around by the dog, who does not listen to him and spends its time freely and unrestrainedly.
