There's a new movie coming out this summer about an insanely-popular (in Japan) comic involving the plot of the last remaining vampire hunter, of which she labors in order to survive by drinking the slain's blood, who is struggling with her ordinance and desire to be accepted. (I am mostly speculating on the plotline; sorry).
If the above piqued your interest, then the jump will provide more relevant information than I could provide on something I have not yet consumed.
Blood: The Last Vampire - Wikipedia, the free encyclopedia
I don't think it should be too hard to find a worthy translated graphic novel; I believe Viz Media (based in Canada) might have produced this series already.
