So basically, I've started reading this manga around 10 months ago and I believe it's a good read! I was looking for a good manga to read cause I was bored at work and I found this very unique story. It's about a group of women who are called "Claymore" because they carry a large two handed sword and they are half monsters ("Yuma" meaning monsters in Japanese I guess).
They are run by an organization that gets paid to get rid of the Yuma. Each of the women have their own unique abilities and talents. The leading character is Clare, and she is awesome!
The story progresses into an even larger scale, going deep into the story of every great claymore and the great monsters. Anyway, I do recommend the read even though there is already an Animated series made. However, the anime is actually just a gist and there are so many other things that happened that wasn't showed in the series.
Read the Claymore manga at One Manga.
