A family has two children—a daughter and a son. Despite appearing human the daughter is actually a female demon, who lives by killing and eating the livestock of her family. The brother finds out and tells his parents, but the parents do not listen to him. Helplessly, the brother escapes to a remote place, where he saves a tiger and a leopard. One day, he comes back home to find that his demon sister had killed their parents and that she was going to kill him next. Just as he is about to be eaten, however, he lets go of the tiger and leopard that he had saved, and they go after his demon sister. The female demon is killed by the tiger and leopard, and the son takes over his home with the leopard and tiger and lives a happy life.
