Himiko travels to the ancient capital of Japan to exorcise a slumbering child, amidst rumors of vampiric attacks. Soon she meets the mysterious, childlike Miyu and her silent, enigmatic companion. Is Miyu behind the attacks? Or does she, too, seek the real culprit?

Himiko is hired to investigate several mysterious disappearances at a school. At the site of each vanishing, a strange doll has been briefly glimpsed. Here she again meets Miyu, now apparently a student, and is told in no uncertain terms to mind her own business.

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 the Shinma gathered together.
