I discovered this series by accident, and it appears that the chapters come out rather sporadically (the most recent one being in Jan. 2013, and the one before that was released in 2011)
STORY - 9: The story is totally unique, and I have never seen anything like it. Basically, there is a cursed girl whose ancestor was called the "Hair Queen." Long ago, there was a "game" of sorts to kill her, and those who attempted the killing were "authors" (users) of "killing goods" (weapons and other tools). The protagonist is the ancestor of one of those killers, but as the "game" resurfaces, he instead
vows to protect the new Queen rather than kill her. The concept of a boy using his powers to protect a girl that he has a special bond with is nowhere near new, but the way that this series goes about portraying it has never before been done.
ART - 8: I really like the way that mostly everything is drawn, but some backgrounds seem to have less work put into them than others. I also did not feel that the art provided anything different that set it apart from other manga. Nonetheless, although I am not the biggest fan of this style, I thought it was well done.
CHARACTERS - 7: The designs of the characters are very well done. Each character looks different enough that you can tell who everyone is and what sets them apart from each other. The relationships are evident enough draw you in to see how certain characters will react with each other, but the depth of some characters as individuals was not shown too well. I'm sure that as the story progresses, I might feel differently, but for now, it was nothing special.
ENJOYMENT and OVERALL - 8: I enjoy the series overall. It causes you to want to read more, and the story is interesting. I did not think that such a concept would attract me at first, but I was pleasantly surprised after I began reading. I would definitely recommend this as something to add to your list of series, especially because it only has 16 chapters so far. The only downside is that it seem as though it takes a long time to be updated.
