Using the Fuzion system, this book brings the world of Usagi Yojimbo to roleplaying. Usagi is a long-running, award-winning high-quality comic book series by Stan Sakai, who provided the illustrations.
The book is written for both comic fans (who may not know RPGs) and RPG fans (who may not know Usagi Yojimbo), and is very thorough. It contains rules, setting, game mastering advice, and over twenty adventures. There is a brief appendix on how to run the game using the Fudge rules, and an episode of the comic entitled "Hebi", which was previously only published in an anthology, not in a regular Usagi comic.
