Usually in stories for this type of out-of-jail situation, the author set it up by having a similar situation that can make the readers infere on a particular Character's capabilities.
For example during the ball of "13th of betrayal" (
chapter 301) we could have had the panic, with some characters assessing the situation, but Henry giving the ultimate order of what to do. Informing that as a 13th crown and head of police his word have weight, even over some other 13th crown for specific situations.
Here it's a bit out of the blue and, to me, hurt the story.
Now we're guessing Henry's power in the society : can he do that all the time ? If it's only sometimes, why for this case ? Etc.
I will admit that for the whole Scala Arc I've been waiting for something to severly impede Iruma, because he's been able - as Narnia says - to accumulate a lot of power fast. And with Kirio out of the picture, Baal being still too much of a challenge ; the story need to present Iruma with opposition, so that he can grow for the next challenge.
Fang Patrol cracking down was perfect for a setback, with the addition of providing a rival, more world building showing that it's a DEMON society and not a human society.
The story hit some of it, but miss the bullseye.
