"D — Twin-Shadowed Knight 1" begins with D slaying a vampire, who leaves the triumphant Hunter with the cryptic words, "Find Muma." Not sure exactly if "Muma" is a person, place, or thing, D travels to the village of Sedoc, where a huge misty crater is attracting the dead for hundreds of miles around. In the village he meets Mia, the lovely young daughter of a fortune-teller, who promptly retains his services. It seems that her mother has foreseen something terrible happening there, and being on her own deathbed, sent her daughter in her stead to try and prevent that catastrophe. But when they go to the newly formed crater to see what could prompt thousands of corpses to rise from their graves and throw themselves into that hole, things get really weird. The D that emerges from the mist brutally dispatches a vigilante group formed by the young men of the village, and begins to act quite unlike himself.
