Claymore is an excellent Japanese animation, with great re-playability.

Period.
There isnt any bad points to this animation.
Period.

Heres the summary to the animation, courtesy of crunchyroll.com

Of course, you can view the animation there too!

The summary does not obviously do justice to Claymore, because its really more about fighting yomas.
Theres also revenge, internal conflicts within the organisation, not to mention the action scenes..
ohhh. if only all animation would be like that.

watch it.
otherwise dont call yourself an anime supporter.

Description:
Alternative title:
クレイモア (Japanese)

In this world, from ancient times, people were eaten by beings called "youma". For a long time, people lived without any means to counter them. However, a half-human, half-youma female warrior was born.... Female soldiers known as "Claymore" who, with silver eyes that can see through to the true form of "youma", and carry a large sword as a weapon, continue to battle those which people have named "youma".
