If you liked the Claymore manga, the Anime-Planet community thinks you'd like:
Long ago the world was split in two: the realm of darkness inhabited by demons, and a land of light where humans dwell. When the king of the dark world decided to unite the two lands, a war broke out that was ended by a dark knight named Sparda. Now the legend of Sparda is nothing but a fairytale, and while most have forgotten it, the bloodline still lives on. Dante is Sparda’s half-human son who, using his twin guns Ebony and Ivory, works as a demon-slayer for hire. One day, his friend Enzo tells him of a new job and with a hefty reward on the line, Dante accepts. In order to claim his reward, Dante must locate a missing girl named Alice, but when his search leads him to a nightmarish wonderland, he must confront his past as he becomes involved in a plan to break the seal to the demonic realm and engulf the world in darkness once more...
There is no denying that Claymore and Devil May Cry are similar. The main characters (Claire and Dante) are so much alike in their cool self-demeanor and personalities in dealing with the people around them. Not to mention that they both conveniently happen to be half-demon/half-human. They also have a very pronounced soft side that comes through when they are interacting with the children they seem to pick up along the way.
Claymore and Fight Stay Night both involve a great deal of action and magnificent fighting scenes. The female characters, Saber in Fate Stay Night and Claire in Claymore have similar personalities in their actions towards fighting. They also express the same thoughts concerning their male companions.
Claymore and Freezing are about chicks who in order to fight monsters, become half-monster themselves. While Freezing starts of bad, after a few chapters it becomes evident how similar it is to Claymore. Those ladies in Claymore spend more time fighting the monsters than themselves, on the other hand chicks in Freezing are more pron to beat the s*** out of each other than fighting monsters. Also Claymore is stronger on gore, while Freezing has some annoying ecchi (at times). If you found the fighting series style appealing in one of those two manga, than you might want to check the other one too,
P.S. Freezing isn't that great story wise, but it does improve slightly after the first 10 or so chapters.

Together they keep England safe from blood-drinking monsters, until a new breed of pseudo-vampire, the Freak, begins attacking people for fun and not to feed. Where are these Freaks coming from and what will Hellsing sacrifice to stop them?
