This one doesn't ease you in, it drops you into a city already rotting, where the hero everybody counted on has been missing long enough that nobody expects him back. The hook is the body horror: cybernetics stolen from Professor Tani's lab turning up welded into the flesh of drug-fried street punks, weapons that fire on a thought because the junkie wearing them can't think straight anymore. Hazuma works it like a case, not a crusade, an ex-cop with a two-bit detective agency chasing a missing scientist, and the show trusts you to sit through the legwork before the metal comes out. The animation is genuinely sharp when it counts, clean linework and real weight in the violence, even if the synth score screams 1993 harder than anything on screen. If you want the RoboCop nerve, corporate-grade tech in the wrong hands and a man rebuilt into something he never asked to be, this delivers it in four episodes with no fat. Watch how it treats the cigarette. That detail is the whole character.

Hazuma, a former cop who now runs his own detective agency, is hired to find a missing scientist suspected of taking cybernetic parts from Professor Tani's laboratory. The stolen hardware is turning up as weapons grafted onto violent cyber-junkies spreading chaos across the city, while the original 8 Man, Tani's cyborg hero, has vanished. When Hazuma is murdered during the investigation, Tani uses him as the template for a new 8 Man. He keeps his detective persona as a cover, but he must balance the cynical private eye he was with the unfeeling android hero he has become. Still carrying the memories and grudges of his old life, this 8 Man fights crime far more brutally than his predecessor. His path also crosses that of Sachiko Yokogawa, the original 8 Man's love interest. Across four episodes, the OVA mixes action, drama and science fiction.
