The kunoichi, Shiyohana, succeeded in capturing Gamo, an underling who had kidnapped a village girl. But it turned out that someone behind Gamo's back had instructed him to kidnap her. His name is Echigoya, a corrupt merchant. After infiltrating the mansion, Shiyohana disguises herself as a maid and confines her target. It seemed as if she had trapped Echigoya with her skills using her superb female body... but her opponent was one step ahead of her. The obscene restraints, the aphrodisiacs and the unexpected torture from Echigoya caused Shiyohana to let go of the reins of her rationality. And what was the end of her journey... "What happened to ...... Shiyohana-senpai?" A kunoichi who has fallen into lust writhes mysteriously. The female dog, breathing hot breath, disappear into the whiteness dyed with mother's milk and semen.
