The Fandom Post is reporting that Discotek Media’s license for the Mad Bull 34 anime has expired. The anime was originally released on VHS by Manga Entertainment back in 1996. Discotek Media picked up the license in 2012, and released it on DVD in 2013.
The anime is based on the manga of the same name by Kazuo Koike that ran from 1986 to 1990 and achieved 27 volumes. It also got an update with Mad Bull 2000 released in 1999 with seven volumes released. Satoshi Dezaki directed the four OVA episodes for studio Magic Bus.
The story of Mad Bull 34 is described as:
Daizaburo “Eddie” Ban, a Japanese-American, joins the New York City’s toughest precinct, the thirty-fourth. On his first day he is partnered up with John Estes, nicknamed “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, even if they pose a minor threat. He 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.
