First off, let me just say, MAN was this manga a FIND. The first time I read the summary saying there were "assassins" and and a pretty girl, I thought to myself, must be a lame weak MC. I have never been more wrong in my life before.
Story: So, like I stated above, the story is about a boy meeting a pretty girl, assassins come to the family, end up recruiting the guy. What I didn't expect was for this manga to be so gruesome and bloody. I'm telling you, the mangaka gives many surprises and...let me just say, ANYBODY can die in here.
