It was one of the darkest anime I've ever watched. The drawing and animation style is interesting but reactionary. It was a weird anime, I personally didn't care for the story underneath. Still, I enjoyed watching this instead of wasting 10-15 minutes of my time. The narrative techniques of the story are told in harmony with the drawings. Although the dialogues sound strange, it adds to the tension. A short-lived anime at a slow pace. I think the anime's use of music could have been better, but the given world really serves its purpose and manages to tension you. In conclusion, if you're notgoing to watch anything else, I suggest you watch it.
