However, Josuke and Okuyasu deduce what is happening from a wound on Koichi's hand and head inside Rohan's house. Rohan uses his manuscript to put Okuyasu under Heaven's Door's power, writing an instruction that will cause him to commit suicide if Josuke tries to help him. Josuke attacks Rohan directly, closing his eyes to prevent himself from viewing his manuscript. Rohan insults Josuke's hairstyle to provoke him into opening his eyes, but this backfires as Josuke loses sight of everything in his rage. As Josuke beats Rohan to a pulp, Koichi explains that when Josuke was four years old, around the same time Jotaro and Joseph fought DIO, he came down with a deadly fever. When Josuke and Tomoko got stuck in a blizzard on their way to the hospital, a student with a regent hairstyle helped them get moving, inspiring Josuke to copy his hairstyle and take offense to anyone who insults it. Josuke, still in a rage, further beats up a surrendering Rohan and wrecks his manga studio.
