Shikaku: Urami Aoi

Toshikatsu Doi, a high-ranking advisor aiming to consolidate power within the shogunate, sends a group of Yagyu swordsmen to different locations, claiming they are there to teach sword techniques. Tokugawa Tadanaga, who was falsely accused and forced to take his own life, had previously instructed his loyal attendant Hyoma Otaki to eliminate the Yagyu group, whom he viewed as corrupt enforcers of the ruling council.
