Chapter 656: Adventure in the Burning Island, had some interesting parallels with one of Oda’s earlier works, Monsters. If you haven’t already, you should read it here at mangafox. A lot of people consider it part of the One Piece canon,
although I’m not exactly sure if Oda himself ever confirms this. and it is! Oda confirms this in SBS Volume 47!
For the newcomers, I added a permanent box below detailing the most current pages on the site! In addition, I recommend starting out with Punk Hazard (current) page, which I will update with my impressions from Monsters this weekend, and how I see it (or don’t see it) relating to One Piece today.
Have a great weekend everyone!
