The ``Soshiro Mizuki'' series, highly praised by Fumio Umezawa, has been made into a complete comic book. The eighth shogun, Yoshimune Tokugawa, began to purge Ooku, which had repeatedly indulged in luxury, and selected Soshiro Mizushiro, who had been used as an account examiner, to serve as a servant in the palace. However, a great evil stands in the way of Soshiro, who rushes forward to carry out Yoshimune's secret mission. Can Soshiro's sword cut through the darkness?
