Summary
Rohan continues to insult Josuke's hair until the time where Josuke approaches Rohan to punch him. As soon as Josuke starts his punch barrage with Crazy Diamond, Rohan shows him a page from his manga, which is simply ignored and Rohan ends up hit by Crazy Diamond's barrage. Koichi then states that even though his eyes are open, Josuke's anger made him unable to see clearly. Rohan says that this was a part about Josuke that wasn't in Koichi's memory and asks him why does Josuke gets so angry about his hair. Koichi then explains that when Josuke was a kid, he got a strong fever. His mom tried to drive him to the hospital but she got stuck on a blizzard. Suddenly, a guy wearing a school uniform helped him and his mom by pushing the car and putting his uniform under the car's wheels so that the guy could pass over the snow. The student then took his uniform jacket and walked away. Josuke took a glance at him and saw only his hair, which was exactly like Josuke's nowadays, as he uses that hair as a homage. Rohan grabs a pen and starts to draw saying that's a wonderful story. Josuke then spots him and continues punching him.
