I know, I've only seen 9 episodes, but what can i say? This anime has seriously captured my heart and soul and whatever is left.
The story, from what i can tell so far, really does deserve 10/10. It is unexpected, especially the latest episode, you can find out yourself but watching it.
The art, is amazing, the detail of the death of people, usually i hate stuff like this but i genuinely love it.
The sound, well i suppose it's average like any other anime, i don't really know how to put an opinion on sound since sound isn't really emphasised as something important, but i think it suits the anime and it give it that little boost that increases the tension in your body >.
