Summaryish:
Recommended. Not an easy read but a light-hearted deeper sci-fi that doesn't let you down with characters or artwork. A little episodic at times.

Well first off lets start with general feel and feelings about it. I really like the feel of the manga as a whole however in the start I almost quit since the dystopia of apathy just felt off and mismatching with the general feel of the story, however you get used to it and just accept the general apathy and resignment, and later on you'll accept it as a part of the world.
Well due to this the general feel isn't as easy to read and always connect with in my opinion but all the much better since its something that (atleast for me) isn't the general thing off it.

Story:
So the world isn't all that fleshed out as it could be but this isn't really a bad thing since its more off a character based story. And it leaves alot to your own imagination or just thinking what it could mean. That means you'll probably be quite disappointed if you can't accept a world that's not all cut and fed to you in bite sized chunks.
The flow of the story is fairly nice(just a few times I felt lost and wondered what happened) and doesn't just stay in the status-quo but moves forward.

Art:
Well what can I say? Crisp nice and no faults and keeps a good level throughout, other then that its all my personal preferences.

Characters:
This is the strongest part of this manga, even though as I said they are apathetic and rarely improve the situations but they are still characters that you can relate to and understand. And its for me hard to dislike the main character not any of the major side characters.

Overall:
Overall I really liked it, but it had a few flaws none of which you can't live with (or love if you're not me). And this really was just the kind of story I was looking for right now so.
Well that's it!
