Wakatono Ha Tsurai Yo [16] (Kosu Mikku Jidai Bunko)

[Machine Translation] Under secret orders from his father-in-law, the 11th Shogun Iesai, Matsudaira Ryunosuke, a master swordsman who risked his life for the peace of Edo, successfully solved the robbery of 30,000 ryo of the shogunate's official money, but his peaceful life did not last. Late at night, he witnessed a man dressed as a peasant wearing an ogre's mask and both of his breasts exposed, slaying a man on the street. He also saved a beautiful samurai girl who was about to commit suicide, and this plunged Ryunosuke into the vortex of political strife. What is the true identity of the devil-masked man dressed as a peasant? What is the "Secret Lip Book"? As he becomes involved with a daughter warrior, a spirited samurai girl, an avenging palace maid, and a female bandit, Ryunosuke, wielding a mighty sword, gets closer to the heart of this bizarre case!
