One thing I have learned after finishing this series, that the world and its society is a one cruel place full with violence, madness, and betrayal, or in the other hand, overpowered by those with the authority.
The Anime itself is divided into 6 different famous Japanese literatures made by famous authors from the past and all of the arcs has no connection with the others, but don't let this make you down because those 6 literatures sure were masterpieces indeed. You may prefer some arcs over the others, but overall it was a roller coaster full of emotions. One has to think deeper to get the full and real meaning of each arc, or as an english teacher would say, you need to think outside the box. You wouldn't really expect what to happen next since it's like a train of irony. You will be left with awe once you finish a certain arc. You will most likely doubt your own instincts since at first you'll be like "ah he's a bad guy", but then later on you'll be like, "wtf I was wrong."
If I can give a number higher than 10, then I would gladly choose that number as Aoi Bungaku's art was a hell of a masterpiece. The art was one of the parts why this show was awesome. The art gave the Anime a mysterious atmosphere and in some part, creepy. Heck, I would be glad if all Anime were drawn like this.
You get different sounds in each arc. The background music that they play when a certain creepy event is happening was so good that it'll make either your eyes closed or wide open, if you're a masochist. Also, when emotional parts strike, the background music really helped to make a viewer sad or cry.
6 different arcs, which mean a lot of new characters. In each arc, you get awesome characters, and by awesome I mean characters surrounded with mystery and such. You wouldn't expect that character would do that to other character such. Also, 2 of the mains in 2 arcs looked like Light from Death Note. :D Plus, you get a 3d guy in every beginning of an episode. Where can you see an Anime with 3d people on!?
Pretty much enjoyed the entire series. There are 6 arcs so normally, one would prefer one over the other. Overall, it was really good. Superb, I must say.
I would frankly say that this is the first Anime I've seen with a different type of storytelling so I'm going to give this a 10. It was very unique. You can't help it but fall in love with the arcs although in some cases, you will most likely hate some of the arcs before you prefer the previous one and wanted that arc to be longer.
