Yay I can help!
So yes Chrno Crusade is going to be coming to the US. From what I understand it is actually coming to TV (I have no idea if it's cartoon network or what that is just what I read).
And since I saw up to ... episode 13 I think I'll give everyone a quicko summary of the show (I believe there is 26 or 24 episodes in the series).
This is definately NOT the cleanest show I have ever seen. Demons explode, splatter and do other gross stuff when shot with Rosette's gun. And the resident scientist/inventor of the covent is quite the pervert. He loves to crawl under benches to try to see under the girls dresses (they are all wearing bloomers so it doesn't really matter) and he makes sexual remarks to them from time to time. Suprisingly there isn't a lot of bad language.
Now for the religious side. When it comes to religion this series is a pile of poop. You thought Kaitou Jeanne was bad? That is nothing compared to this! As far as I could tell there was no real "hell" just a place where the demons lived and were ruled by their "queen." And even though the demons stick their noses all over the place God and angels are absent. Instead there are the "apostles" who were given "special talents by God." The only thing is they were given these talents/powers from birth so they can choose to join the side of the demons. The apostles are able to directly access the astral lines which is where they and the demons draw their power from. It's sort of like the Force from Star Wars since the supposedly all life comes from the astral lines and then returns when that life dies.
Most of the episodes I saw were Rosette and her partner(s) going out to fight demons. She shoots them with bullets with holy water in them and apparently that kills/gets rid of the lesser demons. For bigger ones she uses a special bullet that doesn't have holy water in it but I can't remember why it works.
And yes Rosette's partner is a demon. A "good demon" supposedly, although he hasn't exactly repented. He's just helping Rosette out partly for his own revenge against some demons he was allies with before.
So after thinking about it they got two things right religiously:
1.) God's power is absolute
2.) Demons have a class system. (there are lower class demons and higher class demons)
Am I saying don't try to see it? Not at all, it's an entertaining series, and actually my sister totally loves it and wants to buy it as soon as it comes out. However, I wouldn't recommend it for anyone who is at all shaky about their faith since this series definately twists Christianity. They may change that a little for the dub version though.
