Chapter 73

Ripple Teacher Lisa Lisa (3), originally Concentrated Ripple Power in the WSJ release, is the seventy-third chapter of the JoJo's Bizarre Adventure manga. It is also the twenty-ninth chapter of Battle Tendency.

Summary
The climb up the pillar is difficult because of the oil flowing from the top. Caesar has already made his way a few meters up, but Joseph is having difficulty using the Ripple to cling to the surface. He decides to climb up using an alternate method involving his rolled up shirt as a pole strap. This proves futile, as Lisa Lisa notices he is trying to cheat and cuts the strap with a throwing knife, causing Joseph plummet to the oily depths below, promising to exact revenge on her.

28 hours later, Joseph discovers Caesar's technique of applying his Ripple to his fingers rather than the palm. Joseph successfully grabs onto the surface of the tower and he and Caesar make their way up. 3 hours later, Joseph reaches a stationary Caesar and realizes the pillar has a protruding shape, making it more difficult to climb higher up. Joseph discovers a crack in the surface, and decides to grab onto it to rest. Unfortunately, the crack contains a switch that causes an high-pressure eruption of oil to blast out of the pillar above them.
