What if Black Mirror and Tomie from Junji Ito had a child. This would be it. Just like black Mirror every episode is stand alone exposing some of the dark side of the character. Though we still don't know much about Nanno. Her origin remains unknown and by the end all her deeds seems more of a dream an illusion. I feel like she is the interpretation of karmic retribution
Sometime some of the elements may feel over the top. Overall a good watch
