Yeah, especially in the anime they just watch it like it's theater. I came here to check if the manga does the same and sure the villains take their sweet time to yap. The abilities have these convenient loop holes too. I love the style so I wondered if these mistakes continues in the chapter 150s too...

i think it's because it's not necessarily their job? they are cleaners that take care of trash beasts first and foremost. they don't seem to arrest people, they don't kill them, and they don't give them to other people to arrest either. humans are another organization's jurisdiction, so they probably leave it up to them, especially because the cleaners do not work with this other organization. zanka himself says at one point that he's surprised the raiders/vandals are still walking around in spite of the existence of this organization. it can still be annoying, but i believe there is a general reason for it
Idk why on chapter 21, Enjin's group just chose to let the enemy run away. Why just stand there while they are slowly fading away??? It seems like an overlooked common sense issue and it tickles my nerves.
