Despite being dark themed, having promising pilot, good sound, artwork and character, this show doesn't live up to it's potential. Episodes are magnetic but watching them all lives you unfulfilled. Everything is vague and mystified and it's kept that way. No good explanation, meaning or end can be found even after finishing the anime. Finishing it just lefts you void and unfulfilled. But once you start watching, you keep watching until it's over to find some kind of meaning that you can never find.
I strongly suggest you to not start watching it.
The story had promise, that it could not deliver.
Sound-work is Excellent.
Characters are well built.
The story is too dark without any explanation and sometimes without any logic, that it ruins the potential. Though you keep watching it, it's not very enjoyable.
Overall, I'd say, "stay away". And watch something else with the time.
