Story: Honestly this one is a mess as it goes all over the place. If it wanted to be monster of a week, fine by me. Instead there were some stuff shoehorned last minute in the last few episodes and some confusing motivations. Not only that, there were way too many cop outs and cheap endings from an anime that should of have some action which makes the experience not that exciting at times. Though it is a meh, don't watch this anime for the story and only the concept.
Art: Again meh. When I first saw the concept art, I thought it was okay until I saw the actually anime which is less appealing in my taste. I thought that it would look cutesy and all but instead it is way too detailed and not that moe. The animation is a big meh with some exceptions as the budget seemed to have gone to some other aspects. When it does get good, it's good but it barely happens. I have heard that it went over budget so that might be the case.
Sound: Meh. I did like some of the songs, mostly the cute ones. The voice acting however is really good at least. Just want to point out that the English dub acting is funnier as some of the actresses really put some personality either it be better than the sub or something new.
Character: I'll start with the good. When they act like demons, it's very sexual but it is what I expect. One of the few things I want to see in this series is to see demons getting all hell fire up on yo ass. This series did have some of those moments. Each demon character represent their own sins pretty well in addition of having an interesting interpretation of them.
The biggest flaws is that they did not take advantage of this. There is the fact that they are one dimensional, the fan service gets in the way, and they are suppose to be the good guys. See, I'm okay with demons or bad people being heroes, but it does not work here for many reasons. Their motivations made no sense at times so what is the point, they are way too evil for that, and also they are freaking demons! It's their job to torture people in hell, but nope. The only real demon is into torture while the others are not into it. Ladies, it's your job.
Then you have the main human character, Maria, who is for the most part is bland but her character development is Stockholm syndrome. Also the worse character in my opinion is that demon with blue armor that barely covers her. I just find her annoying, bratty, and not that appealing.
Enjoyment: When it delivers, it delivers. When it doesn't, it doesn't.
Overall: It just gives us what we ask for. That is it. It doesn't do more and sadly less. Do I recommend it, you may need to have some tolerance and not take the series seriously. I ended up comparing this series to Spongebob. Kind of personally enjoy this series despite some of the issues and I don't really care for the fanservice unless I joke around.
