Slow to begin with, and the conclusion will divide readers (I wasn't satisfied.)

The characters are varied in design but in terms of personalty aren't that great, with them either being bland or too "edgy" to really hit home.

Also, some actions and motives from the characters are either stupid/don't make sense or are easily forgiven.

But it does hit its groove and peak in the middle and the story an interesting premise with a lot of potential that doesn't quite get realised.

Overall, this isn't an impressive manga but it's not a complete waste of time. So it's at least worth checking out and seeing if it grabs you.
