Pink Dark Boy is a fictitious manga created by Rohan Kishibe (a character from the fourth part of JoJo's Bizarre Adventure, Diamond is Unbreakable).

On April 19, 2016, during the first Ultra Comic Award event, many participants had to create their own version of Pink Dark Boy, based on what they thought it would be like. 36 works were entered in the contest but none won the grand prize. However, there were two winners for the second prize and three honorable mentions.

On December 28, 2020, Masahiko Aoki tweeted out that he was the one who drew the artwork for the Pink Dark Boy manga seen in the TV Drama. He mentioned that Hirohiko Araki had been the one to draw the rough drafts.
