Masashi Kishimoto
The manga earned a Guinness World Record on December 12, 2012 for Manga written by the most people. The record was due to its "Social Kingdom" campaign in which fans and other artists were given the task of redrawing the entire 26th volume. Participants included manga creators Eiichiro Oda ("One Piece"), Masashi Kishimoto ("Naruto"), Hirohiko Araki ("JoJo's Bizarre Adventure"), as well as voice actors and fans.
