Hyōgo Tsukikage, an invincible masterless samurai who continues a carefree solo journey, travels with Hanji. Along the way, they are joined, somewhat unexpectedly, by Oryō, the proprietress of a transport office at the Shinagawa post station. Meanwhile, Kikyo pursues them, determined to bring Hyōgo back to Edo. As they travel the road together, they repeatedly stir-up incidents and just as often find themselves caught in them.
