I like the writing for this chapter way more than the last one.
The writing has been pretty good most of the time - ESPECIALLY how these demons seem different from every other type I've seen before.
But last chapter was just "hiding your power level is
cowardly!" "Yes, it's cowardly and disgraceful." "Who could even think of something as cowardly as hiding your power level?" "Hiding your power level, what's wrong with you?"
This chapter explains the demon's reaction and how they got tricked way better - and retroactively explains the last chapter better too.

kind of explained it this chapter. There's a difference between hiding your status/power for a bit to surprise someone (visiting town incognito, or an ambush) and doing it as a long term thing. Plus, the 3 demons last chapter stopped limiting their mana as soon as they saw they were going to kill mages.
