It's just a short horror anthology of stories about a moment in time. We don't get much about the past of anything, this is a series that focuses on the now. It can be simple, effective horror sometimes, and others just funny. It's got a Junji Ito energy to it, you won't get an explanation on anything. You just get glimpses into how these ghosts work, about how they can possess, replace, inhabit, or infiltrate a house and implicate death without us ever seeing one.
4/10, I don't like it that much, only one gave me a little chill. The art is decent, but effective horror isn't here at all.
