Story
The story is not bad but is kind of boring and unoriginal. It feels like the story jumps to quick from one point to another. I do like the way it is presented, with little dialogue and exposition.

Characters
I don't have any problem with the characters. There is no background for the characters that is shown to the reader but it doesn't feel like the characters don't have one or they have a bad one.

Art
By far the best thing in Abara. The action scenes are a bit hard to understand sometimes but no other problems. I would recommend you reading this for the art only.

Enjoyment
I have enjoyed this but I think that is mostly because I love Blame!(another manga done by the same author)

Overall
A very fast read(15-20 minutes) so you don't lose much even if you end up not enjoying the story.
