Jin-Roh The Wolf Brigade

The story is set in alternate-history Japan in the 1950s following the atomic bombing and subsequent occupation (by a victorious German Reich, rather than the Allies) of the country at the end of World War II and the post-war recovery. It focuses on Kazuki Fuse, a member of the elite Kerberos Panzer Cops, a metropolitan counter-terrorism unit. Fuse confronts his own humanity when he fails to shoot a young terrorist that his unit traps in the storm-water tunnels. She detonates a bomb in front of him, but only kills herself. The incident damages the reputation of the unit and Fuse is reprimanded. He visits the ashes of the dead girl and meets Kei Amemiya, who claims to be the elder sister of the terrorist and they develop a friendship. Kei is eventually revealed not to be the suicide bomber's sister, but a former bomb courier coerced into acting on behalf of the Special Unit's rival division Public Security.

A trap is set by the local police forces and the Public Security Division intended to discredit the Special Unit with Kei as bait to catch Fuse, intending to show a terrorist passing a satchel bomb to a member of the Panzers. However, Fuse sneaks in, seizes Kei, neutralizes the Capitol Police agents and they escape. Later, Kei reveals her role in the deception and suggests they leave together, but Fuse decides to stay.

They make their way to the tunnels once more, where they are met by members of the Wolf Brigade, a secret, deep-cover unit in the Kerberos Corps led by Hajime Handa. They provide Fuse with a full set of armor and weaponry, before leaving with Kei in tow. Hachiroh Tohbe explains to Kei that the Wolf Brigade has used the Public Security Division's plan to flush out those who were most active in trying to eliminate the Kerberos Corps, and eliminate them in turn. Public Security agents follow a tracking device in Kei's bag and make their way into the tunnels. They encounter the fully armored Fuse, who slaughters them all.

Later, the Wolf Brigade meet in a junkyard and Fuse is ordered to kill Kei to ensure she is never recaptured by Public Security. Kei embraces Fuse and sadly recites the dialogue of Little Red Riding Hood, describing the grotesque appearance of the wolf disguised as a loved one. Fuse is distraught, but regardless kills Kei. Fuse is horrified at his action, but now having sacrificed his humanity, he has no other choice but to remain part of the pack. The old sergeant solemnly compares Kei's fate to the demise of Red Riding Hood and the triumph of the wolf.
