That basically sums up the story here. Smaller story lines tend to form while watching, but end very quickly, often in the same episode. If you enjoy subtle horror, and action as the hero tries to save the day, then you have a good anime here.
But wait! What is this? The last four episodes involve crude humor that is not pleasing in any way... some could call it... freakishly startling? It does have a point in the story line, these weird images they show before and after breaks in the last four episodes, but the story that they are part of is a thought, merely a cell of importance, it would seem that the guy who wrote it thought it would add to the romance which was... there... at parts. It seemed that all it did was turn you away from the show and ruin any good feelings you had for the series.
I would also like to add, due to my love of voicing opinion, that this series is in no way scary seeing as every monster you come across doesn't look scary, and they tend to act stupid and run around in animal suits. It might symbolize something... it might not... but I must say, most of what happened, especially towards the end, made no sense.
With all that said, if you read it all, I STILL favorited the show. I Loved the story. I'm sorry, I know it was somewhat perplexing and had to value, but it was worth watching, it even made me sad when it ended! I was hoping for... a better ending (Like I said, the last four stunk.... bad) but it was poetic and entertaining. I recommend it fully.
