I just finished watching this show and I really enjoyed this.
Nanno an entity (she's definitely not human nobody knows what she is anyway) disguises herself as an high school girl to test the the depth of evil within everyone she targets ( teachers, students). She brings out the hidden lust, rage, jealousy of the person she targets and basically tests them how far they can go. She just manipulates them to see if they give in to their dark desires or not. She brings out that dark side of a human that they try to hide inside of them. This series is twisted, dark in a good way (IDK if it makes any sense). Anyways I freaking loved it. I hope you too.
Definitely recommend this. ENJOY!
