Himiko travels to the ancient capital of Japan to exorcise a slumbering child, only to be confronted with a wave of vampire attacks. Here she meets the mysterious, childlike Miyu and her silent, enigmatic companion. Is Miyu behind the attacks? Or does she, too, seek the real culprit? And if so, why?

Himiko is hired to investigate several mysterious disappearances at a school. At the site of each vanishing, a strange doll has been briefly glimpsed.

Himiko agrees to help Miyu defeat a ghastly armored monster. In return, Miyu tells the tale of how she met Larva, her silent companion.

Himiko travels to Kamakura, a childhood home. There, she dreams of herself as a child, running in terror from a mysterious mansion. Now the mansion has a new tenant: Miyu. Miyu at last tells all - of her discovery of her true nature after her first meeting with Larva, of the secret concealed by Miyu's parents, and of the night that Darkness and Shinma gathered together. And, finally, Himiko realizes what it is that has bound her destiny together with Miyu's... forever!
