I really loved this comic. The plot was great, the characters and relationships compelling and the worldbuilding intriguing (if underdeveloped). It's also beautifully illustrated and brilliantly coloured. 

The one issue I had - which is common with comics and manga - was an occasional brief story that didn't really relate to the overall plotline and as a consequence felt out of place. I imagine that's not really a problem if you're reading a single issue at a time, but as a full book it's a little aggravating. 

Overall though I loved this, definitely among the best comics or graphic novels I've read so far this year.
