I trully enjoyed this series, a realy nice story line with some intriguing caracters (except for Raki who is incredibly annoying with all his whining and crying). There's some low to moderate amount of gore present and some lost limbs and stuff like that, but i din't find it exagerated (most of it is purple anyway).
However, the reason for the 3 stars is that this Anime is not complete, although the discs contain all the episodes launched until now, the story is not concluded. I searched for the manga and apparently this Anime only covers 11-12 volumes of the manga books. The manga itself is not concluded yet, and you might have to wait a while until that is finished and you can see an ending to Claire's story. Altough i don't regret buying this I do hate the fact that the story is suspended like this.
In conclusion: if you want a finished storyline you'll have to wait some more as this is only about 2/3 of the story.
