JoJo's Bizarre Adventure is one of the longest-running manga series. Written by Hirohiko Araki, it began serializing in 1987 in the Weekly Shonen Jump. But, in 2005, it was moved to Ultra Jump. In many ways, the switch allowed Araki to experiment more. Araki added more explicit themes, which helped to draw in a mature audience. It won't be an overstatement to say that it truly took the manga to the next level.
