Daizaburo Edi-Ban, a Japanese-American, joins New York City's toughest precinct, the 34th. On his first day he is partnered up with John Estes, called Sleepy by his friends and Mad Bull by his enemies, a cop who stops crime with his own violent brand of justice. Mad Bull makes no qualms about executing common thieves with shotgun blasts if they even pose a minor threat to him or anyone around them. Mad Bull also often steals from prostitutes and does incredible amounts of property damage while fighting crime. Mad Bull's unpoliceman-like behavior often puts him in hot water with his partner Daizaburo and the 34th precinct. However, despite how reckless or illegal these acts are, a good cause is always revealed (For example, Sleepy uses the money he steals from the prostitutes to fund a venereal disease clinic and a home for battered and raped women). Perrine Valley, a police lieutenant, joins Daizaburo and Sleepy later on to help them tackle more difficult cases involving the mafia and drug-running. Mad Bull 34 is inspired by the high-action buddy cop films of the '70s and '80s. (Source: Thevinnymac)

To the unsuspecting eye Maki, Reimi and Yuka may not look like ace crime fighters, which might explain why they're stuck on traffic patrol instead of more "exciting" police duties. All that changes when Yuka gets herself kidnapped by a white slave organization run by a politically connected businessman who's got the rest of the police cowed. Now it's up to Maki and Reimi to don skin-tight battle armor, liberate a tank, and make sure that a certain slaver learns that when you play with fire, you're going to get your ass burned!
