Ultimate Warriors from Ancient Times, Part 4 (Chapter)

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, the latter easily dodging 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 site of such an unorthodox weapon, presuming that human race may have evolved backwards. Joseph flings the clackers behind his back, making them appear to have vanished. Wamuu is surprised by this trick; giving Joseph the opportunity to launch himself at Wamuu, along with the clackers that were hidden behind his back. Wamuu simply dodges the attack using his supernatural shapeshifting ability, causing the clackers to lodge themselves into a pillar behind him.

Entertained by his opponents 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 and leaving large indent in his skull.
