Overall, I thought it was a great anime, I especially liked the main premise of the show, with the tattoos and special abilities. What I didn't like was the ending, which I'm not gonna spoil here, but I think they should have done it differently. What I mean by this is especially the final fight. You'll get what I mean when you watch it... I would have given an 8 or even a 9 if they would have changed the ending, but ending the show like this, doesn't feel very satisfying and now I wish for a different ending! But to end on a few good notes, I'dsay that the visuals were very pleasing (except for the last episode) and that I never had the problem that I didn't want to continue watching the show, so I have to say that I enjoyed it.
