Chapter 324

Let's Go Play at the Mangaka's House, Part 7 (漫画家のうちへ遊びに行こう その⑦), originally in the WSJ release, is the fifty-ninth chapter of Diamond is Unbreakable and the three hundred twenty-fourth chapter of the JoJo's Bizarre Adventure manga.

Summary
Rohan continues to insult Josuke's hair twice until Josuke approaches to punch him. As soon as Josuke starts his punch barrage with Crazy Diamond, Rohan shows him a page from his manga, which he saw for a while but ignores, and Rohan ends up getting hit by Crazy Diamond's barrage.

Okuyasu says that even though his eyes are open, Josuke's anger made him unable to see clearly. Rohan says that this was a part about Josuke that wasn't in Koichi's memory and asks him why Josuke gets so angry about his hair. Koichi explains that when Josuke was a child, he got a strong fever. His mother tried to drive him to the hospital but got stuck in a blizzard. Suddenly, a man wearing a school uniform helped them by pushing the car and putting his uniform under the car's wheels so they could pass over the snow. The student then took his uniform jacket and walked away. The only part of him that Josuke saw was his hair, and his current hairstyle is a tribute to the mysterious man.

Rohan grabs a pen and starts to draw, saying that it makes a wonderful story. Josuke then spots him and continues punching him. The ending sidenote says that Rohan's Manga "Pink Dark Boy" will be switched to a monthly schedule, possibly indicating that he is either in the hospital or that he no longer has the inspiration for a weekly manga.
