The most important character is Hyakkimaru. He is a complex character, being part - human and part - something else due to the deal his father made. His journey of self - discovery and revenge is the main plot of the novel. Dororo, a young and brave character, is also important. He is the one who helps Hyakkimaru in many ways, both in battles and in understanding the world around them. And there are the various demon lords who are the main obstacles in Hyakkimaru's path, making them important in terms of the story's conflict.
