Tatsuo Nishiyama

Detective Seiji Otaki is determined to find the psychopathic killer of a young woman who was ostensibly a student but in reality a high-priced prostitute. Even though he has been taken off the case for beating up a suspect, he refuses to let it go and recruits his mistress to act as a decoy for the killer. Her involvement turns out to be a fatal mistake, and when her husband gets out of prison, Detective Otaki is in worse trouble than ever.

A cowardly samurai is sent as an official executioner targeting the clan's former sword instructor, a man whose sword and spear skills are second to none.

A shikakenin was an under-the-cover trade that undertook killing in Edo. Hanemon of Otowa, an agency that introduced laborers and maids, was also one of these. Katsugoro Iseya was a timber dealer who had come in as a client. His target was the constructions magistrate Hanno, and the Tatsumiya who sipped on the benefits. Hanemon who had a stong code towards killing, where he would only kill those who do no good to be in the world, accepts this request. Baian Fujieda, a needle doctor would carry out the killing. However, the professional killer Baian fails to bring down Tatsumiya. Hanemon then looks to another shikakenin, the ronin Sanai Nishimura for the role. Although Sanai's ability with the sword is good, he lives poorly in a tenement, and accepts this commission on the condition that it is kept a secret from his wife and child. Here, they close in on Hanno and Tatsumiya again...
