This whole time I was trying to figure out why the humans would put themselves in such a position where they can't defend themselves against dangerous humans. Apparently they thought they had all the dangerous humans under control save for the fiends. I guess when you're as evil and cruel as the humans are, the solution they came up with to try and create a utopian society was actually quite good. They still need a way to deal with fiends though.

And I'm with Fauli on this one, evil won. Yakomaru is Spartacus, he's William Wallace. Fucking Kimomaru is a tool and a house slave. I'm so mad right now.
