During the reign of the eighth shogun of the Tokugawa shogunate, the Yunagaya Domain in the Tohoku region is a small han. But at the han, there is a gold mine. Suddenly, Masaatsu Naito of Yunagaya Domain receives an order to perform Sankin-kotai within 5 days. Sankin-kotai is a custom that requires the daimyo to visit the shogun in Edo. Unfortunately, the time needed to visit the shogun in Edo for Masaatsu Naito is 8 days. Masaatsu Naito also learns he received the order because a high ranking government official wants the gold mine. Also, the expense for Sankin-kotai is high and the Yunagaya Domain is such a small han that it seems impossible to complete. Nevertheless, Masaatsu Naito begins an unexpected operation to complete Sankin-kotai in 5 days.

Only Gohime and Denzo survive. Denzo aims to protect Gohime from the monster, but they also develop feelings for each other.

In 1701, an insult led to a sword slash between the heads of the Ako clan and the Kira clan in Shogun's court. The head of the Ako clan was ordered to commit seppuku, and his loyal retainers plotted revenge against the Kira clan. This led to the legendary events known as the "47 ronin incident". However, unknown to most, the head of the Kira clan, Kozukenosuke Kira, is already dead from his wounds. Impersonating him is his slacker monk brother Takaaki, who has to prevent his brother's death being found out to protect his clan – and accidentally befriends Ooishi, the leader of the Ako men who wouldn't really want to go through with the revenge. Will Takaaki survive with his head?
