It's manga like this that make me despise humanity at times but I can't stop reading it. With the way it started I almost dropped it but it's been getting very interesting. The gore in this is off-putting and the fact they are using children is seriously problematic. They aren't even giving any reasoning. Mabey its orphans? I'm not really sure where they came from but they take a bunch of children mutilate them while they're conscious and turn them into robotic monsters and make them fight monsters. Obviously they have mental problems after that. But anyway all thats left is to see where this goes.
