Chapter 74

Ripple Teacher Lisa Lisa, Part 4 (波紋教師 リサリサ その④), originally in the WSJ release, is the seventy-fourth chapter of the JoJo's Bizarre Adventure manga. It is also the thirtieth chapter of Battle Tendency.

Summary
Caesar pulls out a pen and slowly inserts it into the oil barrier. The pen is cut clean in half, proving the high pressure of the oil flowing out of the pillar. 52 hours have passed and Caesar is forced to try and pierce through head first into the jet. Caesar is able to apply an attaching Ripple to keep his feet on the surface, but at the same time a repelling Ripple on the body parts touching the pressurized oil. By controlling these two opposite Ripples, he is able to slide through the jet and onto the other side with just some loss of breath.

9 hours later, Caesar reaches the top of the pillar, while Joseph is 20 meters below, still stuck at the oil jets. Caesar asks Lisa Lisa to stop the oil, realizing that with Joseph's personality and lack of training, he is likely to jump the barrier and get himself cut in half. Joseph decides to take the leap, but instead of going through the oil barrier, he uses it as a slide, and glides across the surface using the Ripple. Ten seconds later, Joseph is clinging to the outer wall with one hand. Lisa Lisa appears and explains that by sliding on the oil to the other edge, he was able to jump above it where the pressure was least powerful.

Joseph, still clinging to the outer wall, begins to lose his breath since he is not accustomed to his breathing mask yet. His Ripple disrupts, causing him to fall, but Caesar grabs him in the nick of time. After 61 hours and 9 minutes, Joseph and Caesar both reach the top of the pillar and finish the first part of their training. 26 days remain until the Wedding Ring of Death melts.
