Chapter 323

Let's Go Play at the Mangaka's House (6) is the three-hundred-twenty-third chapter of the JoJo's Bizarre Adventure manga. It is also the fifty-eighth chapter of Part IV: Diamond Is Unbreakable.

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 say that he's correct, and since Josuke knows his ability, he is at a disadvantage, and yet he won't come out. 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 trying to run away from the house to bring help. Rohan then uses Heaven's Door to make Okuyasu kill himself if Josuke tries to run.

Josuke enters the room with his eyes closed and tries to attack Rohan. After attacking him to make him open his eyes, Rohan insults Josuke's hair, as it was noted in Koichi's memory not to do it, making Josuke angry at Rohan.
