I'll start by letting you know this over the top fanservice will most likely either drive you away in disgust or keep you glued to the screen while shedding tears of joy. I'm sure some people will just laugh it off or ignore it as well, but it can be pretty polarizing.
Story: 7:/10. The story doesn't really stray from typical shounen plot, but does make use of a few really interesting concepts. For one, it's characters all have powers born of an element from the periodic table (Hydrogen, Mercury, Iron, etc.) and not the usual elements used for this sort of thing (fire, water, earth, etc.) This makes for some rather creative and enjoyable fights throughout the series. Another is it's use of the Christianity in the plot, like a painting of the virgin Mary breastfeeding Jesus containing the power of God. There have certainly been series to do a better job incorporating religion (See: Chrono Crusade), but I'll admit that I surprisingly happy with it considering it was an ero anime.
Art: 8/10. The art for this series is pretty well done, although much of the work clearly goes into breast animation (again, something you either be really happy or really sad about), ass shots. The fighting was rather well done, another surprise for a show of this premise. Overall, I was pleased with the quality.
Sound: 6/10. The "bad shit is happening" track sounded well placed, but everything else was pretty forgettable. This includes both opening and ending themes.
Character: 6/10. Alexander was honestly the only interesting character in the series. With the exception of him, everyone else conformed to some archetype or another almost perfectly. The idea of a of a really short badass who looks like an emo goth sounds ridiculous, but it's honestly the best way to describe him and it worked out rather well. He also has a pretty unique scar carved into the side of his face.
Enjoyment: 8/10. The enjoyment you get from this series all hinges upon how you deal with the fanservice. If you really don't like looking at naked cartoon characters, then this isn't the series for you. If that's your thing, prepare for a full course meal of it.
