The series takes place in the far future, set in a world that mixes modern high-tech images with classic Japanese references. It follows the teenage Rabbit Samurai Yuichi, descendent of the great warrior Miyamoto Usagi, on his epic quest to become a true samurai. But he isn't alone. He leads a ragtag team of misfit heroes including a roguish bounty hunter, a cunning ninja, an acrobatic pickpocket and a faithful pet lizard as he battles depth-charging moles, metal-tipped winged bats, and monsters from another dimension, all in the pursuit to become the best samurai Usagi.
