Black Jack operates in the space between impossible and necessary, a surgeon who breaks every rule to save lives that the system has already written off. The 1993 OVA doesn't waste time justifying him; it trusts you to see a man whose scars run deeper than his face and whose price isn't always money. Each episode is a small moral wound that refuses to close cleanly, and the animation holds every moment of doubt and defiance like it matters, because in this show it does.

An unlicensed physician works in the shadows of the medical world, saving patients that licensed doctors cannot. Kuroo Hazama, known as Black Jack, charges enormous fees for his services, which leads many to see him as greedy and cold, yet no one can dispute his skill or how far he will go for a patient. Alongside his assistant Pinoko, he takes on some of the strangest illnesses imaginable, risking his own life and breaking the law whenever a case demands it. He lives by his own rules and would defy even the will of God to preserve a life. The OVA is a dark medical drama with elements of mystery, adventure and the supernatural, set in the secretive world of underground medicine.
