Stan Sakai is an amazing cartoonist. He brings amazingly historically accurate detail to his comics without departing from his highly stylized cartoon style. The series is set in Japan during the Shogun period and features samurai, ronin, ninjas, and all the scheming and politics of the times. It is what comics aficionados refer to as a "funny animals" book because they characters are animal headed humans, including lions, pandas, rats, rhinoceros,and even bats. The main character is a wandering masterless samurai who just happens to be a rabbit. Don't make the mistake of assuming this just for kids because of the animal heads, there is nothing inappropriate for kids but it is for all ages.
