In the medical profession, there is a name spoken in hushed tones, of an unlicensed genius physician who can save lives—for a price. His name is Black Jack, and he is a dashing, moody figure, caped in black, a Harlock of medicine, a man who lives by no rules other than his own—and the Hippocratic Oath. A man who would defy the will of God himself in the name of preserving life. (Source: AnimeNfo)
