Shiga Hime
A manga about an immortal vampire Miwako who forces a young boy to become her familiar. He is now cursed to hunt humans for their fresh hearts and battle against other familiars.
The setup for this manga is pretty standard in terms of the horror genre. What sets this apart is Hirohisa Sato’s amazing art. Sato’s ability to draw gruesome body horror kept me reading more.
