Diamond is Unbreakable - Chapter 59 [324]
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 reveals that Rohan's manga, Pink Dark Boy, will be on hiatus for the next month.
