Ok, here do we have Zion no Koeda. Sounds fine doesn't it? I thought as well. But I'm afraid I forgot the Japanese excel in using any kind of story/history and mixing it in their own little stories. It can be painful.
Therefore I beg you please: If you have any knowledge of the third empire or west or east Berlin, please do not read this story. It'll be torture.
However, if you weren't the brightest kid in history classes and you haven't the foggiest clue about WW2 or whatever happened there, please do enjoy the yaoi.
Story: 4
The idea of an abduction and yaoi/torture/rape are not exactly original, but can be nice if the mangaka put some effort in it. However, story wise you can't see any effort for historical details.
Art: 5
Nothing new, nothing flashy. Some nice details though.
Character: 3
I cannot possibly imagine a German soldier not getting shot for being gay, let alone a SS'er that doesn't kill Jews. Even in the sweetest fiction. No way.
Enjoyment: 4
It could have been a nice story if I just didn't know. However, I was too pissed off about the little facts that were so incorrect.
Overall: 4
I can imagine someone actually likes this story. So once again: Only read it if you have no history-knowledge whatsoever!
