Chapter 68

The "Blood Clock" Battle is the sixty-eighth chapter of the JoJo's Bizarre Adventure manga. It is also the twenty-fourth chapter of Part II: Battle Tendency.

Summary
Joseph launches one of his Ripple clackers at Wamuu, who easily dodges them with a slight tilt of his head. Joseph explains that his Ripple is still fairly weak, but by charging the clacker with it, he is able to tear through through the pillar men's skin. The pillar men seem fairly amused at the sight of such an unorthodox weapon, presuming that human race may have evolved backwards. Joseph flings the clackers behind his back, making them appear to vanish. Wamuu is surprised by this trick, giving Joseph the opportunity to launch himself at him, along with the clackers that were hidden behind his back. Wamuu dodges the attack using his shapeshifting ability, leaving the clackers lodged in a pillar behind him.

Entertained by his opponent's tenacity, Wamuu slits Joseph's wrist and gives him one minute to defeat him. He commands Joseph to pick up his weapons, but is unaware of  the first clacker which had punctured into the column behind him. The second clacker is flung back towards Wamuu and bashes him directly on the crown, leaving a large indent in his skull.
