Chapter 323

Let's Go Play at the Mangaka's House, Part 6 (漫画家のうちへ遊びに行こう その⑥), originally in the WSJ release, is the fifty-eighth chapter of Diamond is Unbreakable and the three hundred twenty-third chapter of the JoJo's Bizarre Adventure manga.

Summary
Rohan asks Koichi why he thinks that Josuke is hiding behind his office's door. Koichi answers that Josuke is trying to avoid looking at Rohan's artwork. Rohan says that he's correct, and since Josuke knows his ability, he is at a disadvantage. Okuyasu says that he is finding a way to defeat Rohan, which is also confirmed by Rohan. The mangaka then says that Josuke is actually debating whether to run away. Koichi and Okuyasu greatly argue against that, but Rohan simply says that every possibility must be taken into consideration. Rohan then uses Heaven's Door to make Okuyasu kill himself if Josuke tries to rescue them.

Josuke enters the room with his eyes closed and tries to attack Rohan. Rohan throws sharp pen tips at his face to make him open his eyes, but when that fails, Rohan insults Josuke's hair, as it was noted in Koichi's memory that Josuke gets very angry at whoever does so.
