This is... Bad. Very bad. Poor story, execution and art and one of the worst manga I have read in a while. Oh did I mention explicit fan service of children.
Story - 1
The basic concept might have had weight if written by... Anyone else. An us vs them and child soldiers OK. But it's dished out by exposition, explaining things in very silly manners. It's just set dressing to get literal children naked.
Art - 1
Boring, flat, poor direction. This combined with it's amateur quality gives it it's low score. I thought about giving it a 2 for it's robots, which have at least some design
qualities. But it doesn't deserve it.
Characters - 1
I can't really explain how much everybody's character JUST exists for exposition and getting naked.
Enjoyment - 1
I... was cringing and rushing through just to get this finished. Seriously why Is this rated better than Smash Bomber, at least that manga has some cool art!
It's not worth reading. Unless you like children's boobs. Then maybe it'll scratch your itch.
