In "D — Twin-Shadowed Knight 2", the trio hits the road in search of "Muma," running across two technicians who had assisted the vampires' "Sacred Ancestor" in his experiments, and had their lives strangely prolonged in the process. The first is a man named Gii, who has created a ghastly Lovecraftian creature that he worships as a god. His sister Shusha is a ghost now, killed as a witch by villagers she wanted to help and unable to move on due to the artificial heart the Sacred Ancestor gave her. Still able to feel pain, she is tortured by a twisted monk who sends a band of mounted skeletons after D.
