The third episode of Dororo is titled "The Story of Jukai" ¹. Here is a brief summary of the episode ¹:
- The story of Jukai-sensei, a doctor who healed the sick and made prostheses for those who had lost limbs, is told.
- He once worked for Lord Shiba, but after his loved one was killed by Shiba's soldiers, he left and was rescued by foreigners who taught him how to make prostheses.
- One day, he found Lord Kagemitsu Daigo's abandoned and deformed infant on a riverbank and took the child home.
- He made special prostheses for the child, whom he named Hyakkimaru, and taught him how to move about and appear normal.
- After Hyakkimaru killed a lizard demon, Jukai realized that Hyakkimaru's body parts had probably been stolen by demons.
- Jukai inserted swords into Hyakkimaru's prosthetic arms before the young man left to travel the land alone.
- In the present, Hyakkimaru awakens from his sleep and tests his newly acquired ability to feel pain from killing the demon Bandai.
