This yojimbo, as you might have guessed by the name of the book, is a robot. He wanders the land, taking on other robot warriors and trying to act within the rules for the betterment of mankind. And then things get turned upside down. Writer/Artist Sylvain Repos is purposefully vague about the details, but the general outline is that robots have their own set of rules that they need to live by, though they’re not quite the same as Isaac Asimov’s most famous ones.
