15

Black Jack returns to aid his comatose father and be a part of the family, but it is a ploy by his stepmother Renka's father, Zen Mantoku, to obtain his mother's pendant containing the microfiche. Jack refuses, but the organization's henchmen kidnap Pinoko and lure Black Jack in to a trap. Suddenly, Benitokage appears and saves Pinoko and Jack, but another henchman knocks them both out and takes Jack to meet Zen Mantoku, head of the organization and also Renka's father. Mantoku asks Jack to join his organization, revealing that he planted the bomb years ago which injured Jack and killed his mother, and forced Kagemitsu to work for him. Jack refuses the offer, declaring that he has released the secret about the Noir Project to the world. He also reveals the identity of Benitokage who is the first daughter of Kagemitsu and Renka. Benitokage helps Jack escape but he is shot in the leg. He operates on himself, using parts from his father's body with the help of Dr. Kuwata. Later, when Jack and Pinoko are set to return to Japan at the Airport, he is targeted by a sniper, but Benitokage saves his life by sacrificing her own. (Source: Wikipedia)
