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. Koichi goes to talk to them, but he doesn't remember anything due to Rohan's Heaven's Door ability. Okuyasu, however, 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 transforming Okuyasu's hand into a book. He then says that he knows Josuke is hiding behind the door.
