After seeing it on every site I've gone too I decided to do some research on it. It's a manga turned anime that is made by Square Enix, after seeing Square Enix my mind was set that I had to go and watch it. And I did, and I have to say that it is absolutely amazing. It's not just 'generic anime crap' the characters are great, and the plot will really suck you in. The best thing is the characters have depth, something that has been lacking in most of the other anime's that I have watched. In short, go and watch it and then thank me later. I promise it'll be good
