The Promised Neverland Vol. 9 — Manga Raw / Buy Official

The hidden room holds information leading to the human world and a message left behind by Minerva. Minerva turns out to be James Ratri, a human collaborator who could not stop the farm system because of the promise sealed between humans and demons, and who pointed the children toward the outside world and the demons' weaknesses. Emma and the Goldy Pond children resolve on a counterattack to turn the tables and slay the aristocratic demons who come to hunt. New allies like Lucas and Oliver join in, and the reserve of despair transforms into a stage for a full-scale counteroffensive.
