19

Hyakkimaru and Dororo encounter a wild dog which changes into the Thunder-fire Dog and forces Hyakkimaru over a cliff into a river. A villager finds Hyakkimaru and takes to his home, warning him about the demon dog. On the way, they pass a man cruelly beating his dog. Meanwhile the demon dog approaches Dororo and Nota, but it is friendly towards Nota. Hyakkimaru confronts the dog which transforms, but Nota stops Hyakkimaru and the dog departs. To Dororo's surprise, Hyakkimaru says that the dogs share a bond. Later, in the village they see the cruel man is forcing his dog to fight for money, which angers Dororo. That night Dororo puts medicine in the food of the fighting dogs so when the dog-fight starts the next day, the dogs are too sick to fight. The Thunder-fire Dog arrives in town and Hyakkimaru challenges and manages to kill it. However he takes no joy in taking the life of the animal that was possessed by a demon. Dororo finally understands how Nota feels and leaves some flowers on its grave. (Source: Wikipedia)
