The story follows Kasumi as she takes a break from her battles as a Sanada ninja against the Tokugawas. On her way to visit her brother, she meets a young woman named Toyo and stops at Okusawa Village. However, the idyllic setting is a facade; the village is controlled by a corrupt chief, Yosuke, who uses drugs to manipulate the residents.
