The first two episodes are pretty good and quite intense. It was the kind of thing I would expect to scar people for a long time, if it happened to them. However the main character, Rin, doesn't seem to phased by it and neither should you, because it doesn't remain that intense. Allot of the time it is quite light hearted and hugs solve allot of problems.
Generally the series is very short and as such all of the character's emotional turmoil is dealt with pretty quickly. In fact the main characters main emotions are righteous anger and puppy mode, which you might not realize you will love but you probably will. This doesn't mean there aren't any emotions, just don't expect characters to be discussing their feelings that much. The main struggles characters face are to do with friendship, how they deal with their past and finally understanding others. A good portion of the show is like a high school drama, all about making friends, passing tests and keeping secrets.
The end of the show really speeds up, this is because the anime overtook the manga and rushed to the end. It is not as bad as other endings that are like that but there are some things that are skipped and don't seem to the same.For example I feel weird saying Satan is not such a bad guy.
The demons are appropriately horrifying, excluding ones you are supposed to like. They look like they are part monkey and wag their tales like puppies. If you are watching subtitles hope they aren't in yellow like mine were because allot of the floors are yellowy. The English dub is fine except for the first two episodes where the voice acting is just less intense than what's going on.
In summary I liked it, I liked the characters, they were all pretty bad arse but still lovable. The premise and events were interesting and I thought about them a bit, but I was left thinking some things should have been explored more. Some things were a little freaky but there was plenty of cuteness too.
