I read this manga a couple of weeks ago on a friend's suggestion. It got me a few days to finish reading all the chapters 'til the end. It was indeed a quite interesting manga that got me hooked to eagerly finished it.
The general idea was about to protect human being from monsters who ate guts by hiring half human and half monster soldiers which were girls. Along the way it was explained about the monsters' and soldiers' origin too. Long story short, it was all come back again to human nature.
I like the art/illustrations, the imaginative creatures and the storytelling in general although some parts were missing in the middle.
Therefore, I decided to draw the main characters of this manga, Clare as protagonist and Priscilla as the antagonist.
Characters belong to the author.
