Let's Go Play at the Mangaka's House, Part 5 (漫画家のうちへ遊びに行こう その⑤ Mangaka no Uchi e Asobi ni Ikou Sono 5), originally The Terrifying Movement of 'The Hand'! (恐るべき「手」の動き！ Osorubeki 'Te' no Ugoki!) in the WSJ release, is the fifty-seventh chapter of Diamond is Unbreakable and the three hundred twenty-second chapter of the JoJo's Bizarre Adventure manga.
While Rohan is reading Koichi's memories, Okuyasu and Josuke approach his mansion and ring the doorbell. Koichi runs from Rohan and gets to the front door, but as soon as he opens it, he doesn't remember anything due to Rohan's Heaven's Door ability. This happens multiple times until Josuke and Okuyasu begin to get suspicious. Koichi, who is back in the house with Rohan, now begins to feel hopeless. Just then, Okuyasu enters through Rohan's window since he saw Koichi's hand injury. As he is about to punch Rohan with The Hand, Rohan shows him a page from his manga, activating Heaven's Door's power and Okuyasu's hand then body unravels into a book. He then says that he knows Josuke is hiding behind the door.
