"Black Jack" follows Dr. Kuroo Hazama, a brilliant but unlicensed surgeon known only as Black Jack. Marked by a disfigured face and a cloak of mystery, he operates in the shadows of the medical world, saving lives that official medicine has abandoned. Though he demands outrageous fees, his true motivations remain enigmatic—sometimes mercy, sometimes revenge against a system that failed him. Haunted by a childhood tragedy that claimed his mother, Black Jack navigates ethical dilemmas, corrupt institutions, and his own scarred past. Each patient teaches him something about humanity, even as he remains an outsider—a healer without a license, a legend without a name.
