Kiryu Umon is a man disowned by his own father, forced to live as a vagrant, until his supposedly-estranged father suddenly calls him back. Now he finds himself undertaking a mission for the shogun Yoshimune! His job is to help deliver something from Nagasaki to Edo… But as factions collide, this will mark the beginning of a tumultuous journey!
