Story: 8
Extremely slow paced with sharp twists and turns; it's like Mario Kart on 50cc! Its slow pacing allows for slow, thoughtful development of the world the children are moving through, leading to fascinating locations and struggles. Many of the side characters are morally gray, making every encounter tense. Recommended for those who like detailed worlds.

Art: 7
The art, though quite good most of the time, can be smeared or too cluttered in some places, confusing the reader. Art critique is not my strong suit, so all I'm going to say here is that it is a little more than serviceable.

Character: 9
Easily this series' best feature. The aforementioned moral ambiguity of certain side characters leads to long contemplation on their actions, the leading cast is your classic Freudian trio, though it does change later in the story, which is unexpected and welcome (I won't give details to avoid spoilers). The other children who accompany the main cast, I must say, are very poorly developed and progressed. After over a dozen chapter many of them are still just faces you see in the background who chime the occasional quip. Hopefully this changes in the future.

Enjoyment: 9
The story's hyper-dynamism conjoined with classic psychological thriller tropes make this manga immensely fun to read after finishing up other manga from Shounen Jump. Think of it like desert after a large, action-packed Shounen dinner.

Overall: 8
I'm quite optimistic about this manga, I've been proselytizing it like mad for the past several months. It's getting better and better with each new chapter, hopefully it won't trip up.
