The Tale of Zatoichi Noir

The Edo era, on the eve of the Bakumatsu, under the Tenpō era name. Inflation, rice shortages, political corruption, epidemics... In a world where common people suffer, a swordsman who has lost his sight and an Akita dog journey together in pursuit of "justice" and "strength." Where did they come from, and where are they heading? At the end of their path, will they find light—or darkness?
