Well, it sure starts off very dark. It begins with a rape scene before we even learn the characters' names. I was expecting this one to be heavy. I was actually fairly wrong. While it has at least one really dark sequence per episode, overall, this is like any number of visual novels floating around out there. A demon tries to use a young man as the host for the devil while three goddesses try to prevent it by having sex with him (Well, two goddesses do. The third doesn't really since she doesn't actually like him that much). That's the story. It's fairly simple, but the characters' motivations and personalities largely make sense.
The real drawback is the art. The backgrounds look to be stock re-used ones from any number of anime or hentai I've seen. The characters are also seemingly re-used stock models that show up all the time. At least things aren't too terrible, but sometimes characters move (or in one case don't move) in a natural way.
Overall, I'd say I enjoyed it. It told its simple story and didn't attempt to stretch it out longer than three episodes. I'd give this one a 6. It's fair for hentai.
