Summary
Under Heaven's Door's influence, Koichi goes back to Rohan's house, visiting Rohan in his studio. Koichi then sees Rohan finishing drawing a page at astonishing speed, as Rohan was made enthusiastic by reading Koichi's files. Wanting to use every bits of Koichi's memories, the mangaka then rips off yet another page out of Koichi, making him remember than Rohan is a Stand user.

As Rohan plans to keep taking pages from Koichi to inspire his manga, the two hear a doorbell ring. It is Josuke and Okuyasu and Koichi slips away to ask for their help. Unfortunately, the safety lock written inside Koichi makes him unable to warn them and the duo seemingly leaves. However, after Koichi goes back up to Rohan's studio, Okuyasu barges in from a window, as the duo saw that something was wrong after seeing Koichi's untreated cut on his hand. Rohan manages to transform Okuyasu into a book because of his superior speed, then calls out Josuke, aware he is hiding behind the door. The mangaka then converses with the disabled Koichi and Okuyasu about what Josuke could possibly do next, forcing Josuke to act quickly by threatening to make Okuyasu immolate himself. Left with no choice, Josuke goes in the room while closing his eyes. He runs toward Rohan, trying his best to keep his eyes shut, but Rohan uses Koichi's knowledge and taunts Josuke about his hair to make him open his eyes. It backfires as Josuke is literally blinded by rage and doesn't even notice the manuscript as Rohan is violently punched into a bookshelves, releasing Okuyasu and Koichi. Rohan asks why is Josuke so enraged, prompting Koichi to reminisce Josuke's story.

When he was four years old, Josuke fell ill, on their way to the hospital, he and his mother became stuck in the middle of a blizzard, but a mysterious 🇺🇳 helped restart the car, saving Josuke and inspiring him to copy his hairstyle and take offense to anyone who insults it. Rohan, inspired by this story, demonstrates his commitment to his work by attempting to write it down for later use, but Josuke interrupts him and resumes his beating until he retired. Pink Dark Boy is announced to be put on a one month hiatus for "personal reasons".
