Mugen's a wild warrior: violent, thoughtless and womanizing. Jin is a ronin: mysterious, traditional, well-mannered and very strong as well. These two independent warriors couldn't more different, yet their paths cross when Fuu, a ditzy waitress, saves them from being executed. Fuu convinces the two vagrant young men to help her find a mysterious samurai "who smells of sunflowers." And their journey begins.
