Shroi kiba (1974)

Yosuke Arimitsu, an elite detective in the Investigation Division of the Metropolitan Police Department, shot dead Muraki, a childhood friend's colleague detective and brother of his lover, Kyoko, and was stigmatized as a vicious detective who has something to do with the underworld. However, this was a trap set up by the mastermind behind the underworld, and it was Muraki who was actually associated with the violent organization, and the shooting was also due to self-defense. However, Arimitsu had no way to prove that fact, and he had no choice but to speak for the honor of his colleagues and for the happiness of his beloved Kyoko. Arimitsu will leave the Metropolitan Police Department, although he was not charged with insufficient evidence. Arimitsu, who became a criminal collapse, decided to live as a "case shop" who undertakes cases that the police can not handle at the request of his former boss, grass cutting. Eventually, Arimitsu discovers the existence of a great evil that has upset the fate of himself and Kyoko.
