Shikaku: Urami Aoi

Doi Toshikatsu, a high-ranking advisor who seeks to consolidate power within the shogunate, dispatches a group of Yagyu swordsmen to various locations, claiming they are there to teach sword techniques. Tokugawa Tadanaga, who was wrongfully accused and forced to commit suicide, had previously ordered his loyal retainer Otaki Hyoma to eliminate the Yagyu group, whom he regarded as corrupt enforcers of the ruling council.
