Mugen is a wild and fierce fighter whose combat technique is influenced by breakdancing. Jin, on the other hand, is a solitary ronin samurai who roams the land by himself. Although they aren’t exactly companions, their journeys frequently intersect. When a scatterbrained waitress named Fuu helps them escape trouble with the local authorities, they decide to accompany her on a quest to find the “samurai who smells of sunflowers.”
