Chapter 164

The Smiling Devil (笑顔の悪魔) is the one-hundred-sixty-fourth chapter of The Promised Neverland manga.

Synopsis
While Mujika and Sonju are arrested by the high-ranking demons for treason, demon civilians and soldiers are unsure if they really are traitors as everyone claims. Meanwhile, Peter threatens the captive children in order to receive information about Emma, Ray and Norman's whereabouts, their plans for the future, and the "Promise".

Plot
The high-ranking demons arrest Mujika and Sonju for treason. However, demon civilians and soldiers are unsure if they are traitors, as everyone claims. The so-called traitor's blood had prevented the demons from degenerating.

They soon conclude that the high-ranking demons hunt down those with the special blood because the latter will get in the way of the farm's desire to rule over the demons. In other words, if demons did not have to eat humans to prevent degeneration, the farms would not have so much power. They conclude that the Queen and the aristocrats used the farms to control the demon population as they saw fit.

The demon children, Awla and Mawla, beg the demon soldiers to help their parents from the unjust imprisonment. But they cannot do anything about liberating their parents. The best they can do is help the demon children.

Meanwhile, Mujika begs the high-ranking demons to spare the citizens she has cured with her blood.

Three days later, November 13, 2047, at the Grace Field House, Peter Ratri receives news that those who received the evil blood have been disposed of. Just like Peter ordered and Mujika and Sonju will be executed the same day. Now that he has gotten rid of those who will threaten the farm system, he only needs to eliminate the escapees.

Peter bends down to a tied up Nat and teases him about Emma, Ray, and Norman, pointing that he knows that Nat lied about them being dead. Not only that, but Peter is also a bit deranged and snaps Nat's fingers and starts beating him for lying.

The escaped children are afraid for Nat's wellbeing. The young man tries to put their minds at ease by putting on a brave face. However, the torture continues as Peter no longer cares if the cattle are well treated. He will do anything, even killing the children, to determine if the children have made a new "Promise".
