The Aka Yomihime, or Red Biblioprincess, otherwise known as the custodian of the Bibliotheca Razielis Archangeli. A girl with the appearance of a small child, she has short green hair and golden eyes, although her left eye covered with an eyepatch attached to her keyhole. She has a very strong sense of balance, and tends to leap very slowly and gracefully or twirl atop of furniture without much trouble. She will answer questions with "Yes" or "No" in German rather than Japanese. It seems that she doesn't have any issues with the Professor's intentions, and seems to enjoy watching his plans unfold. She has an uncanny calm persona, and doesn't show much consideration for typical human affairs, such as death, pain, destruction, and so on. She and Dalian appear to share a very vicious and spiteful relationship.

Hugh Anthony Disward inherits an old mansion and a personal library from his grandfather. In the basement of the mansion, he meets a mysterious girl, Dalian. She is a Dantalian and a gateway to "Dantalian's bookshelf", which stores the prohibited books of the demons.<br><br>
"Gensho (Illusory Books)", the prohibited books, endanger the balance of the world, but people are fascinated by the taboo. Hugh and Dalian solve the cases involving Gensho with their ability to access the Dantalian bookshelf.
