“And Emma… your weakness is being naive.”
The Promised Neverland features an overarching story with a terrible, previously revealed underlying secret. Best to start reading with volume 1.

This volume builds off the revelations of the first as the children start to formulate plans and decide how best to proceed. Themes of appearances vs reality and the ongoing impacts of choices each character needs to make are escalating and nicely interwoven. Krone provides a good third “side” and adds interesting new context and complications to everyone’s maneuvering. To complicate things further, Emma and her compatriots must deal with the possibility of a traitor in their midst in the wake of bringing others into the fold.
One of the things I like most about this manga is how smart everyone is without being infallible. And on the flip side, how they can be wrong or make small missteps without acting foolish. It’s a hard aspect to balance properly, and so far author Shirai is doing an excellent job of it.
Good followup volume overall continues to build a complex web of characters and agendas while keep a real sense of dread and tension pervasive.
