The concept is intriguing. Nanno is a very peculiar character, whose nature is a total mystery. I liked the fact that each story was made to convey a moral message to the viewer and I think some of those messages were really important.
Nanno is absolutely unpredictable. Her behaviour is so ambivalent, but at the end of the day the protagonist of each episode is the sole person responsible for their demise.

The show explores the human mind in a very deep, mysterious and horrific way. It shows how people are often manipulated by their impulsive emotions and a little trigger is all they need to become killers, monsters, deceiving liars or criminals.

The most important thing to remember is that each episode is a story in itself. As such some episode might be better than others. I particularly liked the second and eighth episodes. If you decide to watch this, just remember that you may hate some episodes. I think this aspect makes the show strangely polarising, depending on how many episodes you actually liked.

The music was so good and when they played the Danse Macabre in the third episode, I couldn't help it but feeling over the moon. It was a big surprise for me, I love that piece.

I recommend it to everyone who loves some scary mystery.
