The Medieval Ages Dark Knights' Murder Training Grounds, originally Chamber of the Two-Headed Dragon in the WSJ release, is the thirty-second chapter of the JoJo's Bizarre Adventure manga. It is also the thirty-second chapter of Phantom Blood.

Summary
While gliding on the giant leaf, Poco asks how Jonathan and Zeppeli created the giant leaf. Speedwagon, however, quickly inquires about Zeppeli's past. Zeppeli obliges him and begins to explain his past with the Ripple.

Two years after Zeppeli's first encounter with the mask, he swore to find it, searching the world for it without a clue as to its whereabouts. Eventually, his search led him to India, where he found a young man who called himself a doctor. The doctor, merely by touching his patient's leg, magically healed it. Zeppeli realized that what the doctor just did was the opposite of the Stone Mask's powers; giving life instead of stealing it. Zeppeli asked how the doctor got his powers, and was told to go up the Nuu River and look for his master Tonpetty. Arriving at Tonpetty's temple, Zeppeli approached Tonpetty to shake his hand. Tonpetty greeted Zeppeli, but he also gave him a warning that if he trained there he would face an evil enemy and die fighting him.

Zeppeli tells Speedwagon and the others all of this, but leaves out Tonpetty's prophecy because he wants to keep it a secret. Unexpectedly, Tarkus jumps after Jonathan and company to grab them. Thinking quickly, Jonathan says that they should all jump to the building and abandon the leaf, which they do, and Tarkus crashes into the side of a tower.

Jonathan believes that Tarkus is dead, but his conceptions are shattered when Tarkus crawls out of the hole he made in the tower. Zeppeli says that they must stop Tarkus from chasing them, so he tells Jonathan to take Poco into the knights training ground. Poco advises against this course of action, saying that the knights' training ground is riddled with traps. Just as he says this, Jonathan opens a door, causing a neck brace on a chain to come down and pull him up to the ceiling.

Tarkus, having sensed Jonathan's location, enters the room. He recognizes it as the “Lair of the Two-Headed Dragon" where he had fought death matches over 300 years ago. The nostalgic Tarkus puts on a neck brace similar to Jonathan's.
