Black Jack

After seeing him at Kreutzer's hospital, Black Jack goes after Dr. Stein, a major leading expert on prosthetic limbs and organ transplants. Black Jack also encounters a woman whom he was familiar with. He discovers that Stein was about to perform an operation that would attach an experimental robotic arm to an aspiring pianist. Black Jack fails to get any answers from Dr. Stein, but does talk to the boy who was about to receive the robotic arm. Black Jack talks to the boy that was about to receive the new arm. The boy admits that he didn't want the robotic arm which would enable him to play the piano with simple thought but would rather keep his human arm and learn to play the hard way. Black Jack saves the boys arm, and then attempts to follow Dr. Stein to England.

Black Jack finally arrives in England to hear of a man who's been in a coma, unaged, for 65 years. Dr. Stein wants to analyse him to find out why he hasn't aged, thinking it will give them information about eternal youth; but the patient's niece has hired Kiriko to put an end to it. Black Jack operates, but afterwards the patient ages and dies upon finding out that his family had died.

Black Jack is alive because his mother, Mio's pendant stopped the bullet from hitting him. He operates on the doctor's mother and discovers a Type Hydra artificial heart. It is a heart that keeps on pumping even when it is extracted from the host. They replaced the Type Hydra with another artificial heart that Black Jack requested and saved her life. They discover that the Type Hydra was designed by Hazama Kagemitsu, Black Jack's father through a microfiche that was inside Mio's pendant. The doctor's mother tells Black Jack how his parents met and how she got the artificial heart.

Black Jack is called by Renka, he thinks that about his father but she says she want him to stay and be a family, but Renka's daughter thinks Black Jack is after his father's fortune. When about operating on his father, the organization henchmen kidnap Pinoko and lure him in a trap, in which he gives up the pendant. Benitokage appears and saves the day, apparently because one of the Organization knocks Black Jack and then he awakes to meet Zen Mantoku the former leader. He tells that the reason of his father to leave Black Jack and his mother was to protect them from the Organization (meaning the bomb that near killed Black Jack was a plot of the organization) it is revealed who Benitokage is, and then both of them work together to escape. At the end Black Jack is aimed with a Sniper Rifle in which Benitokage saves his life using her.
