Steel Ball Run - Chapter 91
High Voltage, Part 2 (ハイ・ヴォルテージ その② Hai Vorutēji Sono 2), originally The New World, Part 2 (新たな世界② Arata Na Sekai 2) in the UJ release, is the ninety-first chapter of Steel Ball Run and the eight hundred forty-third chapter of the JoJo's Bizarre Adventure manga.
Within stopped time, the alternate Diego casually deviates Johnny's nail bullet and reminisces how Valentine came to his world to convince him to follow him and take the Corpse for himself, as Valentine respected Diego's ambition and didn't wish for Johnny to keep it for himself. Diego accepted and went underground, exploiting a momentary distraction from Johnny's part to steal the corpse. Time resumes and the knives hit Johnny who is unhorsed. Diego departs but Johnny shoots several nail bullets toward Diego who has to stop time to avoid the holes Tusk ACT3 creates. Diego grasps the dangerousness of Johnny's Stand and devises a plan to kill him as Johnny deduces the timestopping ability of THE WORLD.
Johnny then finishes the 8th stage at the 5th place and immediately goes to one of the boats transporting the horseracers toward Coney Island. Meanwhile the speaker reveals that the results of the Steel Ball Run race are still unclear, as Johnny, Diego, Norisuke and Pocoloco can seize the first place.
In the boat Johnny thinks up how he can overcome Diego's power within the last 15 km of the race. When Johnny disembarks, he sees his father, George, waving at him and showing him Nicholas's boots as a silent reconciliation. Johnny is moved and continues the race as George publicly apologizes for mistreating his son. Following Diego into the alleys of New York, Johnny figures that he must outwit Diego and only barely get in range. Suddenly Diego disappears again, and has hung wires to trap Johnny. Johnny collides with them.
