The Promised Neverland: Volume 1 (Manga)

Emma, Norman and Ray are the brightest kids at the Grace Field House orphanage.  And under the care of the woman they refer to as "Mom," all the kids have enjoyed a comfortable life.  Good food, clean clothes and the perfect environment to learn - what more could an orphan ask for?  One day, though, Emma and Norman uncover the dark truth of the outside world they are forbidden from seeing.
