Summary
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.
