The best part of this anime is the premise. It is original, interesting and had me hooked. I especially like the blend of romance and psychological horror. It gives the show a very tense feeling that makes the romance lively.
So why doesn’t it get a ten? The pacing is too slow. While the premise takes a while to set up, the plot grinds to a halt very quickly. This pace does somewhat add to romance/horror aspects of the story by adding atmosphere, but it doesn’t stop some parts from being dull. Each episode feels like one episode stretched into 2. Many of the themes and characters flaws end up getting over-repeated just to fill space. There is also some filler, which is unnecessary for a 12-episode anime.
Even so, I enjoyed it a lot and the other aspects are good enough to make the pacing forgivable. I would recommend it. Some good advice, if you find the ending slightly unsatisfying then I highly recommend the last OVA. It gives the horror aspect a little boost and is a great setup for the second season.
