Personally I feel like this manga has done a good job with portraying the Adventurer's Guild as brutal and ruthless with the succubi, and here the succubi as brutal and ruthless with everyone else. If Amor(a) hadn't been abused, the guards who found her would have killed her like all the others. You can see, on page 18, the corpse of a succubus also dressed in rags and looking the same size as her, and so probably a child. But they killed all of them except Amor, and would have killed her if she hadn't ran away successfully.
I think withholding the extent of the succubi's crimes until now was also a good decision; before we had only really seen their persecution justified in terms of the possible damage they could do, if they enchanted people to murder each other. (There was also mention of leaving people drained and one guy in a coma, but that wasn't the way it was framed by Espada.) Here we see a very damning picture of them, but if you read between the lines, it's clear why they're like this. That's not an excuse, but it's no wonder that succubi society would be so focused on strength and shunning the weak, and ruthlessly using others.
And when succubi commit mass kidnapping and enslaving people to use until they die, with nothing but violent predation on others, it's clear why those others will ruthlessly kill them even to the children. But that's not an excuse, either; as we saw it the first time, it was a brutal slaughter of a whole group of people.
It's not revolutionary or anything but I think this was a very good portrayal of how these sorts of cycles of violence and oppression can exist and be an awful, self-perpetuating tragedy. Without making that the focus or explicitly pointing it out, just having it there and plain.
And the main heart of this update was beautiful, even with Halo relying on the text of a children's story and still thinking of Amor as a kid even knowing she's an adult, because she is a fucking idiot. But this did have her open up somewhat about herself to Amor, instead of just fully quoting the book... It also explains to me why Amor acts so childish, despite her age; because she was fucking abused, raised in an emotionally stunted culture, and that on top of having to hide in the ruins all the time.
Why the fuck is this manga so good?
