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, a strange doll has been found. Here she again meets Miyu, now apparently a student. Miyu has designs on the body, and perhaps the soul, of the school hero, Kei. But so, it seems, does another...

Himiko agrees to help Miyu defeat a ghastly armored monster. In return, Miyu tells the tale of how she met Larva, her silent companion. Later, Himiko learns of the tragic fate of a husband and wife. Meanwhile, a beautiful young man with a ghastly laugh circles and waits. Who is he? What is the secret of the Armor? And what of the Shinma? Can Himiko put the pieces of the puzzle together in time?

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!
