Chapter 91

Caesar: A Lonely Youth, Part 4 (シーザー孤独の青春 その④), originally The Fight Between Light and Wind!! (光と風の激突!!) in the WSJ and tankobon releases, is the forty-seventh chapter of Battle Tendency and the ninety-first chapter of the JoJo's Bizarre Adventure manga.

Summary
Caesar's Ripple proves to be far stronger than Wamuu had predicted. Wamuu tries to retreat within the mansion, but Caesar cuts his legs with a Bubble Cutter and plans on finishing him with a Ripple Kick. However, Wamuu purposely fell back so that the kick's impact would knock him into the hotel. Caesar enters the hotel too and finds the wounded Wamuu waiting for battle in the main hall.

Outside, Joseph and Lisa Lisa approach the hotel. They look for Caesar and Messina, but all they find is a severed arm.

Back inside, Wamuu prepares his Divine Sandstorm but is stopped at the revelation that Caesar placed hundreds of Bubble Cutters around him. Caesar reveals that his Cutters can act like lenses, refracting the sunlight and magnifying it in Wamuu's position. Wamuu freezes in place when Caesar goes in for the finishing blow, but for a single instant, Wamuu was within Caesar's shadow, allowing him to pull off a devastating Divine Sandstorm.
