Let's Go Play at the Mangaka's House (3) is the three-hundred-twentieth chapter of the JoJo's Bizarre Adventure manga. It is also the fifty-fifth chapter of Part IV: Diamond is Unbreakable.

Summary
After reading all of Koichi 's memory and his adventures with the stands, Rohan says that he will take off his memories and that they will serve as inspiration for his work. Koichi then uses Echoes Act 2's power to attack Rohan, but all of his attacks miss due to the fact that Rohan used his Heaven's Door ability to write in Koichi's memory "You cannot attack the mangaka Kishibe Rohan". Rohan reads Toshikazu's memories as well, but discovers that he is a terrible person and none of his readers would like a character like that. Koichi then questions why Rohan would do this, saying that he is already famous and rich even without reading his memories. Rohan replies saying that he doesn't write manga to be famous and rich, but to be read. Rohan then rips off part of Koichi's memory. Remembering nothing that happened there, Koichi and Hazamada leave Rohan's mansion satisfied with the visit. Koichi then discovers that he lost 20 pounds on that day.
