As the children reach the conclusion of the first season of The Promised Neverland anime, there are still plenty of unanswered questions. If you don’t want to wait until 2020 to find out what’s next for Emma, Ray, and the rest of the kids, your best bet is to pick up the manga. There are a total of 13 volumes and counting (only nine of those are officially translated) of the manga, but we have two suggestions as to where you should start.
The Promised Neverland anime ends with Chapter 37 of the manga, so you’ll want to read Chapter 38 in volume 5 to see what happens next. Though that’s a place where you can start, I highly recommend going back and reading from Chapter 1. The Promised Neverland anime’s production team took some liberties with their adaptation to make it a more exciting (and tense) viewing experience. The manga features quite a few monologues and other great moments that were ultimately cut or trimmed for the anime. The tone of the manga can be different at times too. I guarantee you’ll have a better sense of the world of The Promised Neverland if you start with the beginning.
