Highway Star, Part 6 (ハイウェイ・スター その⑥ Haiwei Sutā Sono 6), originally No Problems! (何も問題はない！ Nani mo Mondai wa Nai!) in the WSJ release, is the three hundred eighty-ninth chapter of the JoJo's Bizarre Adventure manga. It is also the one hundred twenty-fourth chapter of Diamond is Unbreakable.
Having reached the end of the alley on the dock whilst trying to outrun Highway Star, Josuke stops and hides behind a container. They get distracted by a swirling pattern in the water, which Highway Star uses as an opportunity to sneak up on them; but when they attack, they swipe empty air. Highway Star searches for Josuke and finds them speeding away on Rohan's motorcycle in a drainage pipe right below the docks, the source of the swirling water Josuke noticed moments earlier.
Josuke manages to escape the drainage pipe and into drain bank in Morioh Town, but runs out of petrol in the bike. Thinking quick, they jump off the bike and use Crazy Diamond to climb into a parked car not far away and tricks Highway Star by falling out and locking it inside the vehicle. They then rush to "fix" the motorcycle, aware that Highway Star could and may well warp out of the car at any moment.
