EDIT: I finally read Berserk. I can see why people made the comparison. For my analysis, check out http://forums.animesuki.com/showpost.php?p=1351679&postcount=17 . I believe that I wrote objectively and in-depth about the similarity between these two manga that has apparently become such a major issue to people who are commenting on these series.
Wow. I love this manga. Normally, fantasy manga just take a few particular cliches aspects of fantasy as a wrapper for a show with characters & plot that are very close to non-fantastic storylines. But all the reviews for this one were so high, I decided I'd check it out.
The art is nice. The characters and objects of the world are drawn uniquely, and the action scenes are drawn in a way which makes me wish I could see them animated. The ecchi is /very/ ecchi, it's almost like smut. (Koinzell is a real player....) And on that note, his character is also very complex. We come to understand his motivations a bit, but still, his behavior is far from 1D--at times he's a bit awkward, at times kind, in battle deadpan and sometimes also frantic. His behavior also kinds of throws you off since... he's so small, like a pre-teen boy really.
The pace is nice, the interactions are (so far) all completely unrepetitive, there have been no random irrelevant hold-ups in the plot--there's zero feeling of "same old, same old" as you read it (it's fantasy/adventure in a hostile world, but it's very different from formulaic plot progression like you see in Immortal Rain, Kurohime, etc.).
5 volumes are out so far, eh... Volume 0's plot developments went by especially quick, but Volume 1 Chapter 1 clearly takes it time more, so I'm not sure how far this series will extend. I hope 30 volumes, over which the plot of the series changes constantly with new relevations like it did at the end of Volume 0, to reveal as many different aspects of the fictional world of Ubel Blatt (what does that mean anyway?) as possible. 😀
It's not very far scanlated yet, but since I can change my vote later I'll put in a 10 for now.
