Highway Star, Part 8 (ハイウェイ・スター その⑧ Haiwei Sutā Sono 8), originally I'm the One Who'll Get Mad!! (怒っているのは俺だ!! Okotte Iru no wa Ore Da!!) in the WSJ release, is the one hundred twenty-sixth chapter of Diamond is Unbreakable and the three hundred ninety-first chapter of the JoJo's Bizarre Adventure manga.
Josuke defiantly crawls toward Yuya until he can't move anymore. Yuya, satisfied, resumes his conversation with the three girls in his room. He gloats, being healed from his injuries and now possessing a keen sense of smell. He then smells a great deal of anger and asks who among his three companions is pissed off. This person is Josuke, who proceeds to rise from the ground.
Confused, Yuya sees that Josuke drunk his IV, which is full of vitamins and glucose, empowering Josuke. He tries to make Highway Star attack Josuke, but at close range, Crazy Diamond is the fastest and breaks Yuya's leg. Cornered, Yuya tries to remind Josuke of Rohan, which doesn't faze him, and switches to tell him that it would be underhanded to hit an injured man. However, Josuke reveals that he already fixed him.
Yuya is then overjoyed, but his happiness is cut short when Josuke reminds him that this is now a fair fight. Crazy Diamond repeatedly pummels Yuya and sends him through the window in the hospital's fountain, which satisfies Josuke deeply. The aftermath of the fight is presented: Yuya is still hospitalized and is forbidden from using Highway Star. Rohan is recovered but his feud with Josuke continues. Koichi goes to walk his dog as he originally intended earlier.
