Claymore is an amazing anime about these half-human, half-yoma(demon) women who were created by an organization to destroy these demons called "yoma".
It follows the story of one Claymore warrior in particular, named Clare. I thought the series was amazing. I started and finished watching it in December right around New Years. It was suggested to me at a time when I really needed some new anime, something new and fresh besides what I'd already seen and it didn't disappoint! I was so addicted that I got mad when it ended!
If you've seen it, feel free to add your thoughts. If you have not been so lucky as to see it then visit the Claymore thread on my site. I have all the episodes linked on there!
