Well, it'd be wrong to say the human side is being driven by logic per se. The king speech made it obvious, he made use of fear as the drive to push the humans to unite for the sake of greed and power, making the witches a common enemy (which is a lie to let the authorities make experiments and studies on the witches bodies and magic to reach the goals I said before).
Not sure how this is going to be, but assuming the above is accurate, there is bound to be a third party pulling strings in the shadows. So Humans vs Witches doesn't feel like the right call there, even if that's how it looks for now.
The art is quite well done, but I'll be disappointed if it really turns into a boring "Irracional Human" Vs "Saintly Witches" brawl.
You say warped logic that's funny this manga so accurately represents us humans because we are always scared of things we dont understand or that are more powerful than us which makes us obsessed with the idea that it must be destroyed which in this case is exactly what it is but it is flipped around the witches were never a threat and the king knows it and he said it himself that God made them so they were supposed to help humans but humans didnt give 2 shits and just said fuck it I wanna be god....it is warped but it is sadly true
They want to be god alright, but it is the guys pulling the string behind scenes who are making use of fear and greed to control the people into a fight against witches. I rather not misunderstand, because it isn't "their nature to do so" but they're being driven to do so by a bunch of plotters that use the authority of the king to make their plans work. Even that king that is suffering a slow death thinking he's done the best for the human's development was played by into their script. Their real objective? it isn't war or erradication of the witches. it is to get to experiment on the witches to find a way to wield their power. They (the bunch of people at the lab) want to become the witches themselves, even if it cost the extermination of a race and the decimation of their own. That's how *warped* they are.
Just... what? Everything happened so fast like whaaaat?? I liked the story regardless but still, it was really disturbing to see how warped the logic of all the humans there. Wow. I was shook.
