The Promised Neverland

In Grace Field House, life couldn't be better for the orphans. Together with the other children and a kind "Mama" who looks after them, they form a big, happy family. No child is ever overlooked, especially since they are all adopted at the age of 12. Their daily lives involve rigorous tests, but afterward they are allowed to play outside. There is only one rule they must obey: never leave the orphanage. But one day, two top-scoring orphans, Emma and Norman, venture past the gate and discover the horrifying truth behind their entire existence: they are all livestock, and their orphanage is a farm raising food for a mysterious race of demons. With little time to carry out an escape plan, the children must somehow change their fate.
